Understanding Metabolism

Metabolism is the sum of all chemical reactions that happen in your body to keep you alive. It’s how you turn food into energy, repair cells, regulate temperature and even think. Some of these processes run in the background—breathing, digesting, pumping blood—while others kick in when you move or exercise. And yes, everyone’s metabolism runs at a slightly different pace. In my opinion, that pace can make a big difference in how you feel day to day.

Signs of a Low Metabolism

Ever feel like your body is stuck in molasses? There are a few tell-tale signs: • You gain weight easily, even when you haven’t changed what you eat.
• You feel tired or sluggish most of the time.
• You’re always cold, especially in your hands and feet.
• Your skin is dry, hair is brittle or you notice hair thinning.
• You struggle with constipation or slower digestion.
• Brain fog sets in—you can’t concentrate, ideas just won’t come.
• Your mood dips, maybe you feel a bit blue more often.

These symptoms don’t guarantee a slow metabolism, but they’re red flags worth paying attention to.

Why Metabolism Slows Down

A few things can drag your metabolic rate down. First, age—metabolism naturally slows as you get older. Muscle mass drops off, and muscle burns more calories at rest than fat does. That means if you lose muscle, you burn fewer calories without lifting a finger.
Hormones also play a big role. Underactive thyroid (hypothyroidism) is infamous for slowing everything down. Sex hormones like estrogen and testosterone can affect how you store fat and build muscle. Chronic stress pumps out cortisol, which can interfere with metabolism over time. And then there’s genetics—some people are simply wired to have a slower engine.
Crash diets and severe calorie restriction might sound effective, but they can backfire. Starve your body long enough and it shifts into conservation mode, slowing your metabolism to hang onto every crumb. It’s frustrating because you might feel like you’re doing everything right, but your body thinks you’re starving.

Health Consequences of Low Metabolism

When your metabolism is sluggish, it’s not just about the number on the scale creeping up. A slow metabolism can lead to insulin resistance, increasing your risk of type 2 diabetes. Blood lipid levels may worsen, putting you at higher risk for heart disease. Energy levels stay low, which can turn physical activity into a chore and create a vicious cycle—less movement means fewer calories burned, which means more weight gain, which further slows metabolism.
Mentally, you might notice mood swings or low motivation. And the fatigue isn’t just tiredness; it can feel bone-deep, the kind that doesn’t lift after a good night’s sleep. Over months or years, poor energy balance can contribute to muscle loss, weaker bones and even hormonal imbalances that affect reproductive health.

Everyday Impact on Your Life

Picture this: you wake up late because your body didn’t get the memo to kick into high gear. You skip breakfast since you’re rushing. By midday you’re craving carbs to jolt yourself awake, and by evening you’re worn out. Sound familiar? Low metabolism can turn simple routines into uphill battles.
Social plans? You might bail on a hike because you’re too tired. Work—or study—suffers when brain fog sets in. Relationships can fray if a lack of energy makes you irritable. And food becomes a constant source of guilt instead of enjoyment. It’s hard not to feel frustrated when your own body seems to be working against you.

Simple Steps to Give Your Metabolism a Nudge

You don’t need fancy supplements or extreme regimes. Try these practical tweaks: • Build muscle. Strength training two or three times a week helps increase resting metabolic rate. More muscle means you burn slightly more calories even when you’re on the couch.
• Eat enough. Undereating can backfire. Aim for balanced meals with protein, healthy fats and fiber-rich carbs. Protein requires more energy to digest, giving your metabolism a little boost after you eat.
• Stay active. Small bursts of movement—taking the stairs, a quick walk—add up. It doesn’t have to be a marathon session.
• Sleep well. Poor sleep disrupts hormones that regulate appetite and metabolism. Shoot for seven to nine hours.
• Manage stress. Try deep breathing or short breaks. When cortisol stays high, your body clings to fat and slows energy use.

And here’s a rhetorical question: would you rather tweak a few habits now, or struggle with low energy and weight gain later? I think the answer is clear.

When to Seek Professional Help

If you’ve made lifestyle changes and still feel like you’re trudging through life, talk to a doctor. Blood tests can check thyroid function, vitamin levels and other markers. A registered dietitian or endocrinologist can help diagnose conditions like hypothyroidism or hormonal imbalances. Sometimes medication is needed to get your metabolism back on track. Don’t shrug off persistent fatigue or unexplained weight gain—you deserve answers.

Putting It All Together

Low metabolism can feel like an invisible wall that turns every task into a challenge. But it isn’t a life sentence. With a few tweaks—lifting weights, eating enough, moving more, managing stress—you can give your metabolism the support it needs. And if you’re still spinning your wheels, professional guidance can shed light on hidden issues.
I believe most people have more influence over their metabolic rate than they realize. It’s not about a quick fix or magic pill. It’s about steady, consistent steps that add up over time. So start small, pay attention to how your body responds, and be patient. Change doesn’t happen overnight, but with persistence, you can get your engine running more smoothly—and feel better in the process.

What is Metabolism?

Metabolism refers to the biochemical processes that occur within every living organism – including humans – to maintain life. These processes allow us to grow, reproduce, repair damage, and respond to our environments.

Defining Metabolic Rate

The metabolic rate is a measure of how fast your body burns calories, which are units of energy consumed through food. A higher metabolic rate means more calories burned and, generally, a greater ease in maintaining or losing weight.

Components of Metabolism: Basal and Active

Basal metabolic rate (BMR) refers to the amount of energy expended while at rest in a neutrally temperate environment, in the post-absorptive state. This means that the digestive system is inactive, which requires about 12 hours of fasting in humans. Active metabolism, on the other hand, includes calories burned during physical activity. What else.

Factors Influencing Metabolic Rate

Genetic Determinants of Metabolism

Genetics play a crucial role in determining metabolic rates. Some people inherit a speedy metabolism, which means their bodies are more efficient at processing nutrients and calories.

The Role of Hormones in Metabolic Regulation

Hormones such as thyroid hormones and insulin directly influence metabolic rate. For instance, an underactive thyroid (hypothyroidism) can decrease metabolism, leading to weight gain, while an overactive thyroid (hyperthyroidism) can raise metabolism.

Impact of Age and Sex on Metabolism

As we age, our metabolic rate generally slows down, a phenomenon linked to loss of muscle mass and hormonal changes. Additionally, men typically have a higher metabolic rate than women, partly because they have more muscle mass, which burns more calories at rest.

The Science of Metabolism and Weight Loss

How Metabolism Regulates Body Weight

Caloric Intake vs. Metabolic Burn: Balancing the Scale

To lose weight, you need to burn more calories than you consume, which can be achieved by either reducing your caloric intake or increasing your physical activity to boost your metabolic rate.

Adaptive Thermogenesis and Weight Loss

Adaptive thermogenesis refers to the body’s process of producing heat in response to environmental changes and dietary intake. During weight loss, the body’s metabolism can adapt by becoming more efficient, burning fewer calories—a factor that can lead to weight loss plateaus.

Metabolic Adaptations to Weight Changes

Effects of Long-term Dieting on Metabolic Rate

Prolonged dieting can lead to a decrease in metabolic rate as the body strives to conserve energy in response to reduced calorie intake. This can make further weight loss more challenging.

Metabolic Plateaus: Understanding the Stagnation

A metabolic plateau occurs when your body adapts to weight loss and burns fewer calories. At this point, many people see their weight loss stall despite continuing with their diet and exercise regimen.

Metabolism encompasses the intricate web of chemical reactions that occur within living organisms to sustain life. These reactions are essential for converting food into energy, building and repairing tissues, and eliminating waste products. Understanding metabolism is crucial for grasping how our bodies function and maintain homeostasis.

What is Metabolism?

Metabolism is broadly divided into two categories: catabolism and anabolism. Catabolism involves the breakdown of complex molecules into simpler ones, releasing energy that the body can use. Conversely, anabolism is the process of building complex molecules from simpler ones, which requires an input of energy. Together, these processes ensure that cells have the energy and materials they need to grow, reproduce, and repair damage​ (Encyclopedia Britannica)​​ (Nature)​.

The Role of Enzymes

Enzymes play a pivotal role in metabolism. These protein molecules act as catalysts, speeding up chemical reactions without being consumed in the process. Each metabolic pathway is governed by specific enzymes that facilitate the conversion of substrates into products. For instance, the enzyme pyruvate dehydrogenase converts pyruvate, the end product of glycolysis, into acetyl CoA, a key molecule in the citric acid cycle​ (Nature)​. Click for more.

Metabolic Pathways

Metabolic pathways are series of chemical reactions occurring within a cell. Two primary pathways are glycolysis and the citric acid cycle:

1. Glycolysis: This pathway occurs in the cytoplasm and breaks down glucose into pyruvate, yielding a small amount of ATP (energy) and NADH (an electron carrier). It does not require oxygen, making it an anaerobic process.
2. Citric Acid Cycle (Krebs Cycle): Taking place in the mitochondria, this cycle processes acetyl CoA to produce ATP, NADH, and FADH2 (another electron carrier). This pathway is aerobic, requiring oxygen​ (Encyclopedia Britannica)​.

Balancing Anabolism and Catabolism

Cells must maintain a balance between anabolism and catabolism to ensure metabolic homeostasis. When energy or nutrient supplies are low, catabolic pathways are activated to release stored energy. Conversely, when energy is abundant, anabolic pathways store energy by synthesizing molecules like glycogen and fat​ (Nature)​​ (BioOnline)​.

Factors Affecting Metabolism

Several factors influence an individual’s metabolic rate, including age, sex, body composition, and activity level:

• Age: Metabolic rate generally slows down with age due to the loss of muscle mass and hormonal changes.
• Sex: Men typically have a higher basal metabolic rate than women, primarily due to greater muscle mass.
• Body Composition: Muscle tissue burns more calories than fat tissue, even at rest. Therefore, individuals with more muscle mass have a higher metabolic rate.
• Physical Activity: Exercise increases metabolic rate by building muscle and increasing the amount of energy the body uses during and after activity​ (Rush Health)​.

Hormonal Regulation

Hormones like insulin, glucagon, and thyroid hormones play significant roles in regulating metabolism. Insulin, for example, promotes the uptake of glucose by cells and stimulates anabolic processes like glycogenesis (the formation of glycogen from glucose). Glucagon, on the other hand, triggers the breakdown of glycogen to release glucose when blood sugar levels are low​ (BioOnline)​.

Metabolic Disorders

Disruptions in normal metabolic processes can lead to various metabolic disorders. For example, diabetes mellitus is characterized by impaired insulin function, leading to elevated blood glucose levels. Hypothyroidism, where the thyroid gland produces insufficient hormones, results in a slowed metabolic rate, weight gain, and fatigue. Conversely, hyperthyroidism accelerates metabolism, causing weight loss and increased energy consumption​ (Encyclopedia Britannica)​​ (MIT Department of Biology)​.

Current Research and Applications

Research in metabolism extends beyond understanding basic biological processes. Scientists are exploring how metabolic pathways are altered in diseases like cancer, where cells exhibit abnormal metabolic behavior to support rapid growth and division. Understanding these alterations can lead to the development of targeted therapies that disrupt the metabolic processes of cancer cells without affecting normal cells​ (MIT Department of Biology)​.

Moreover, studying metabolism in different states, such as hibernation or fasting, can reveal insights into how organisms adapt to extreme conditions, potentially leading to novel medical treatments and strategies for preserving human health during space travel or severe medical conditions​ (MIT Department of Biology)​.

Practical Implications

For individuals looking to manage their weight or improve their health, understanding metabolism is key. While basal metabolic rate is largely determined by genetics and physiological factors, lifestyle choices such as diet and exercise play crucial roles in modulating overall metabolic health. Eating a balanced diet rich in whole foods and engaging in regular physical activity can optimize metabolic function and support long-term health​ (Rush Health)​.

In conclusion, metabolism is a complex but fascinating field that underscores the dynamic and adaptable nature of biological systems. Ongoing research continues to unravel its mysteries, offering promising avenues for medical advancements and a deeper understanding of life itself.

Introduction

In today’s modern society, weight gain has become a prevalent issue, particularly in the United States.

Unhealthy Diet

Another prominent factor contributing to weight gain is an unhealthy diet. The availability and consumption of processed foods, high in refined sugars, unhealthy fats, and empty calories, have increased dramatically. Fast food and sugary snacks have become convenient choices for many individuals, leading to excessive calorie intake and weight gain. Sugar free treats and snacks can help.

High-Calorie Beverages

In addition to unhealthy food choices, the consumption of high-calorie beverages is a significant contributor to weight gain. Sugary sodas, energy drinks, and sweetened beverages have become staples in the American diet. These drinks not only contribute to excessive calorie intake but also lack nutritional value, promoting weight gain and compromising overall health.

Emotional Eating

Emotional eating is another factor that influences weight gain in the United States. Many individuals turn to food as a coping mechanism to deal with stress, anxiety, or other emotional triggers. This unhealthy relationship with food often leads to overeating and the consumption of calorie-dense foods, resulting in weight gain over time.

Lack of Sleep

Sleep deprivation has been linked to weight gain and obesity. In today’s fast-paced society, many individuals prioritize work, social activities, and screen time over a good night’s sleep. Lack of sleep affects hormone regulation, leading to increased hunger and cravings, as well as a decrease in metabolic rate. These factors contribute to weight gain and hinder weight loss efforts.

Medications

Certain medications prescribed for various health conditions can also contribute to weight gain. Some medications, such as antidepressants, antipsychotics, and corticosteroids, may alter metabolism, increase appetite, or cause fluid retention. It is essential for individuals to discuss potential side effects with their healthcare providers and explore alternative options if weight gain becomes a concern.

Medical Conditions

Certain medical conditions can contribute to weight gain or make weight management more challenging. Conditions such as hypothyroidism, polycystic ovary syndrome (PCOS), and insulin resistance can affect metabolism, hormone levels, and energy balance, leading to weight gain. It is crucial for individuals with these conditions to work closely with healthcare professionals to manage their weight effectively.

Age

Age is another factor that plays a role in weight gain. As individuals get older, their metabolism naturally slows down, leading to a decrease in calorie expenditure.

Discover the benefits and risks of legal steroids in enhancing metabolism. Our comprehensive guide provides a detailed overview of what legal steroids are, how they work, and the science behind their impact on metabolism. Explore how legal steroids can help improve your physique, boost your performance, and take your fitness journey to the next level.

Many individuals turn to anabolic steroids when building muscle, burning fat, and enhancing athletic performance. However, these performance-enhancing drugs are illegal and have many dangerous side effects. Legal steroids have emerged as a safer and more effective alternative to anabolic steroids in recent years. But what exactly are legal steroids, and how do they affect metabolism?

Legal steroids are natural supplements that mimic the effects of anabolic steroids. They are formulated with high-quality, natural ingredients scientifically proven to enhance muscle growth, increase strength, and improve athletic performance. Unlike anabolic steroids, legal steroids are free from harmful side effects and are legal to use.

One of the primary ways legal steroids affect metabolism is by increasing protein synthesis. Protein synthesis is the process by which the body converts protein into muscle tissue. Legal steroids help promote muscle growth and repair by increasing protein synthesis. This, in turn, helps to boost metabolism, as muscle tissue burns more calories at rest than fat tissue.

Legal steroids also help increase energy levels and endurance, improving your overall athletic performance. They do this by increasing the production of red blood cells, which carry oxygen to the muscles. This allows you to work out for longer periods without getting tired, ultimately helping to burn more calories and boost metabolism.

Another way in which legal steroids affect metabolism is by reducing cortisol levels. Cortisol is a hormone that is released in response to stress. High cortisol levels can lead to increased fat storage and a slower metabolism. Legal steroids help to reduce cortisol levels, which can help to promote fat loss and boost metabolism.

So, how do legal steroids compare to anabolic steroids? While anabolic steroids are known to produce rapid muscle growth and strength gains, they come with a host of dangerous side effects, including liver damage, infertility, and even death. Legal steroids, however, are free from harmful side effects and are legal to use.

In conclusion, legal steroids are a safe and effective alternative to anabolic steroids that can help to enhance metabolism, promote muscle growth, and improve athletic performance. They increase protein synthesis, boost energy levels and endurance, and reduce cortisol levels. Legal steroids may be worth considering if you’re looking to take your fitness journey to the next level. As with any supplement, it’s important to consult with a healthcare professional before use to ensure safety and efficacy.

As we age, our bodies undergo several changes that affect our metabolism. Metabolism is the process by which our bodies convert food into energy. It’s a complex process that involves several organs and hormones working together. When our metabolism slows down, we burn fewer calories, which can lead to weight gain and other health problems.

The Causes of Slowed Metabolism

One of the main causes of slowed metabolism is a decrease in muscle mass. As we age, we lose muscle mass, which reduces the number of calories we burn at rest. This can lead to weight gain and a slower metabolism. Additionally, hormonal changes can also play a role in slowed metabolism. For example, menopause can cause a decrease in estrogen levels, which can lead to weight gain and a slower metabolism.

The Effects of Slowed Metabolism

A slowed metabolism can have several negative effects on the body, including weight gain, decreased energy levels, and a higher risk of chronic diseases such as diabetes and heart disease. Additionally, a slower metabolism can lead to a decrease in muscle mass and bone density, which can increase the risk of falls and fractures.

Ways to Boost Metabolism as We Age

Fortunately, there are several ways to boost metabolism as we age. One of the most effective ways is to engage in regular physical activity. Exercise can help increase muscle mass and improve hormonal balance, leading to a faster metabolism. Additionally, eating a healthy diet that is high in protein and fiber can also help boost metabolism. Foods such as lean meats, fish, nuts, and whole grains are all excellent choices for boosting metabolism.

Another way to boost metabolism is to get enough sleep. Lack of sleep can lead to hormonal imbalances and a slower metabolism, so it’s important to get at least seven to eight hours of sleep per night. Additionally, drinking plenty of water can also help boost metabolism by keeping the body hydrated and allowing for optimal metabolic function.

The Role of Genetics in Metabolism and Age

While lifestyle factors such as diet and exercise play a significant role in metabolism and aging, genetics also play a role. Some people are born with a faster metabolism than others, and this can be influenced by genetics. However, it’s important to note that even if you have a slower metabolism due to genetics, lifestyle factors such as diet and exercise can still help boost metabolism and improve overall health.

Conclusion

In conclusion, metabolism and age are closely linked, and a slower metabolism can lead to several negative health effects. However, by engaging in regular physical activity, eating a healthy diet, getting enough sleep, and staying hydrated, it’s possible to boost metabolism and improve overall health as we age. While genetics play a role in metabolism and aging, lifestyle factors still play a significant role in overall health and wellbeing. By making healthy choices and taking care of our bodies, we can age gracefully and enjoy optimal health and wellness.

Are you aware of the adverse effects of sugary drinks on your health? Learn about the negative impact of consuming sugary beverages and the potential health risks associated with it. Discover the science behind the correlation between sugary drinks and health and make informed choices to protect your well-being.

Consuming sugary drinks, such as soda, energy drinks, and fruit juices, has become a common practice worldwide. However, the excessive intake of these beverages can lead to several health issues. In this article, we will explore the adverse effects of sugary drinks on health and the science behind this correlation.

Understanding Sugary Drinks

Sugary drinks are beverages that contain added sugars, such as sucrose or high-fructose corn syrup. These beverages are often high in calories and can cause a sudden increase in blood sugar levels. The most common sugary drinks include soda, energy drinks, sports drinks, sweetened tea, fruit juices, and some coffee drinks.

The Negative Effects of Sugary Drinks on Health

The overconsumption of sugary drinks has been linked to several health problems, including obesity, type 2 diabetes, cardiovascular diseases, and dental decay. Here are some of the adverse effects of sugary drinks on health:

Obesity

Sugary drinks are high in calories and low in nutrients, making them a significant contributor to obesity. Research has shown that people who consume sugary drinks regularly are more likely to be overweight or obese. A study conducted on children and adolescents found that those who consumed sugary drinks regularly had a higher risk of developing obesity.

Type 2 Diabetes

The consumption of sugary drinks can lead to insulin resistance, a condition where the body becomes less sensitive to insulin, leading to high blood sugar levels. This can eventually lead to type 2 diabetes. A meta-analysis of studies found that people who consume sugary drinks regularly have a higher risk of developing type 2 diabetes.

Cardiovascular Diseases

Sugary drinks can also increase the risk of cardiovascular diseases, such as heart attack and stroke. A study found that consuming sugary drinks regularly can increase the levels of triglycerides, a type of fat in the blood, which is a risk factor for cardiovascular diseases.

Dental Decay

Sugary drinks can be harmful to teeth and cause dental decay. The sugars in these drinks combine with bacteria in the mouth, leading to the production of acid, which can erode tooth enamel. A study found that children who consume sugary drinks regularly are more likely to have cavities than those who don’t.

How Sugary Drinks Affect the Body

Sugary drinks can have several negative effects on the body, including:

• Increase in Blood Sugar Levels: The high amount of added sugars in these drinks can cause a sudden spike in blood sugar levels, leading to insulin resistance and eventually type 2 diabetes.
• Dehydration: Sugary drinks can lead to dehydration as they do not contain enough water to compensate for the diuretic effect of caffeine and sugar.
• Decreased Brain Function: Studies have shown that consuming sugary drinks regularly can lead to decreased brain function, including memory and learning.
• Increased Inflammation: The high sugar content in these drinks can lead to inflammation, which can contribute to the development of chronic diseases.

Conclusion

The overconsumption of sugary drinks can have detrimental effects on our health. These drinks are high in calories, low in nutrients, and can lead to various health problems such as obesity, type 2 diabetes, cardiovascular diseases, and dental decay. It is important to note that even drinks marketed as “healthy” or “natural” can contain added sugars that are harmful to our health.

Reducing or eliminating sugary drinks from our diet can have a significant impact on our overall health and well-being. Drinking water, unsweetened tea, or coffee, and natural fruit juices in moderation can be a healthier alternative to sugary drinks.

By understanding the science behind the correlation between sugary drinks and health, we can make informed choices to protect our well-being. It is crucial to pay attention to the nutritional value of the beverages we consume to maintain a healthy lifestyle.

Sometimes picture is better than a thousand words. What if we just look at the US statistical maps for obesity and heart disease and see how they relate to lifestyle and nutrition?

The full maps are shown at the bottom of the page, and if you examine them, you will see that:

• heart disease rate and obesity are almost perfect overlap;
• obesity, heart disease and percentage of inactive adults are in very good correlation;
• obesity, heart disease and soft drink consumption are very good correlation;
• higher fruit and vegetable consumption in most cases correspond to lower rate of obesity and heart disease;
• higher meat and poultry consumption usually, but not always correspond to lower rate of obesity and heart disease;
• solid (saturated) fat consumption does not correlate with obesity and heart disease

Most of these results reflect what we already know: sugar-rich foods are the worst for health.

A noticeable good effect of meat and poultry consumption is in line with research that shows that protein rich diet is best for weight loss and exercise.

It is also interesting, that we cannot see no bad effect of higher saturated fat consumption.

Lets focus on the southeast region. I highlighted and numbered four areas for more careful analysis: San Antonio / Austin Texas (area 1), Mississippi (area 2), Northern Georgia (area 3), and Southern Florida (area 4)

Area	Obesity	Heart Disease	% Inactive	Soft drinks	Fruits and vegetables	Meat and poultry
1	Low/Med	Low	Low/Medium	Medium	High	High
2	High	High	High	High	Low	Low
3	Low	Low	Low	Low	High	High
4	Low	Low	Low	Low	Medium	Low

Region 4 is an exception for meat and poultry consumption, with low meat/ poultry and low obesity. Because this is South Florida, I suspect that people there substitute various fish and seafood for meat. But based on the other three regions, we can see that high meat and poultry consumption is certainly compatible with good health.

I did not use saturated fat for this sub-analysis, because the way it is concentrated on the map (the bottom one) probably reflects higher cheese and milk consumption in North Central states. It doues not show clear correspondence to any other map.

Below are full versions of these maps (taken from www.cdc.gov and http://maps.ers.usda.gov/FoodAtlas/).

To understand the claim in the title of this article, we need to start with the basics. All nutrients you get with food can be divided in two categories: essential and non-essential.

Essential means “indispensable” – they are the ones that your body does NOT make on its own.

Non-essential nutrients are the ones that your body does make on its own. You body’s ability to go from one nutrient to another is as follows:

• All carbohydrates (sugars) can be made from proteins and fats. They are non-essential nutrients.
• Fats can be made of any other nutrient, with an exception of essential fatty acids (EFAs: omega-3 and omega-6) that must be obtained with food in small amounts.
• Protein is an essential nutrient. Protein cannot be made completely from scratch, because 9 out of 20 protein building blocks, called amino acids are not made in our body and therefore must be obtained with food. They are essential. This means that we must eat protein to build our own.
• Carbohydrate, fat and protein can all be used to produce energy. The default energy source is carbohydrate (glucose); if glucose is not available then your body will readily burn fat and then protein. Carbohydrate, fat, and protein together are called macronutrients (“macro” means “big”), to stress the fact that we get most calories in food from them three.
• Water, vitamins and minerals are all essential: they are not produced in our body and must be obtained with food. (To be precise, some water is produced in your body, but that amount is not nearly sufficient to keep you alive).

The following diagram represents these rules:

Since I majored in biochemistry this simple concept about nutrition is as obvious to me as multiplication table, yet I find that so many people are unfamiliar with it.

So if you are trying to build a low-calorie diet that is balanced and contains all essential nutrients, does it mean that you have to get obsessed with looking at those nutritional facts and count all those calories and grams of fat and protein? Well, the answer is both yes and no. You need to understand basic facts about foods once, and after that you will not have to worry too much about how those numbers add up.

Below are three simple rules you can use to build a well balanced diet:

1. Carbohydrate rich foods that contain no or little essential nutrients can be safely reduced to a minimum. That is the easiest way to keep your calories low. I call it a carbohydrate avoidance strategy. If protein content is below 5 grams per serving – reduce this food or exclude it from your diet. This way you will stay low on calories automatically, without having to count them.
2. Build your diet around animal protein-rich foods. The best ones are those that have calorie to protein ratio anywhere between 5 to 10 (using kilocalories and grams for protein). Examples are meat (with fat trimmed off), milk, poultry, eggs, fish and “light” cheese. In these foods, most calories will come from fat, which it fine. Regular cheese and sausages are bad examples, because in those foods, calorie to protein ratio is about 20. That is way too many calories per gram of protein. You can still include these, but limit serving sizes.
3. Include a variety of plant products – oils, vegetables and fruits to supply essential fatty acids and vitamins. Use a normal portion size for oil, about half ounce (15 ml). Green veggies, salads and fruits are unlimited, because they are very low in calories.

When on a fitness program, best results are achieved by cutting carbohydrate to a minimum while increasing protein intake. Here is an example of how reducing carbohydrate while keeping the total energy intake the same results in improvements in weight loss (this particular experiment was in obese women; all diets were reduced in calories, from Meckling, 2007):

Carbohydrate to protein ratio (in calories)	Exercise included?	Weight Loss (kg) over 12 weeks
3 to 1	No	2.1kg
1.5 to 1	No	4.6 kg
2.7 to 1	Yes	4 kg
1 to 1	Yes	7 kg

We can see that reducing carbohydrate relative to protein while keeping the total calorie intake constant results in a better weight loss. The best combination for weight loss in this experiment was 1 to 1 carbohydrate to protein diet in combination with exercise.

To make certain important chemicals in our body, called leukotriens and prostaglandins, we need two kinds of essential fatty acids: omega-3 and omega-6. (Omega-9 fatty acids advertised on some supplements are not essential.) There are several different subgroups in each class, but we will just refer to omega-3 and omega-6 to keep it simple.

Despite the presence of many products on the market advertized as “omega-3 supplements” the truth is that you can easily meet your daily need for both omega-3 and omega-6 essential fatty acids with 2 servings (1oz, 30 mL) of canola or vegetable cooking oil, or blended oils that include eigher one of these two. The trick is that these two common oils are very high in omega-3, and most other oils are high in omega-6. So you could use either pure canola and vegetable or blended oil like canola/corn or canola/vegetable. Important: olive oil is a poor source of essential fatty acids, despite being more expensive. Here is my full article about this. Including 1 to 2 servings of plant oil is also good for another reason: polyunsaturated fat in your diet may reduce risk of cardiovascular disease, although some scientists argue that evidence is not strong enough to claim this.

Your customized diet

You are ready to build your own diet customized to your needs. One common mistake is attempting to write a weight loss diet from scratch, and abandon most foods you love to eat. It is a very bad idea. Your feeding habits took years to form, and you will feel very unhappy without foods you love. Your chances of sticking to such a diet in a long term are fairly low.

Much better idea is to analyze your current diet and make adjustments to it based on your goal. I call this method do-it-once calorie adjustment. Here is my detailed article about it.

The idea is that when you are starting you diet and fitness regime, do a summary of foods you eat, including protein content and calorie content. You really do not need to include fat and carbohydrate here, since you know that they can be converted one into another. In protein-rich animal foods, most energy comes from fat; in plant foods it is both fat and carbohydrate, but all you care about istotal calories. Most certainly, your breakdown of foods will fit on one page. Example:

Food serving	Calories	Protein	Calorie to Protein ratio	Notes
1 egg	70	6	11	OK
120g (4oz) sardines in tomato juice	156	24	6.5	OK
120g (4oz) tuna in water	133	28	4.7	OK
1 cup (240 mil, 8oz) 2% reduced fat milk	130	8	16	limit
1 cup whole milk	173	11	16	limit
120g (4oz) chicken breast	220	32	7	OK
0.5 oz (15mL) plant oil	120	0	—	Must have 2 servings
Potato, large	250	7	36	Limit
360 ml (12oz) beer, regular	140	0	—	Exclude
360 ml (12oz) beer, light	100	0	—	Limit
120g (4oz) pork	280	28	10	OK
113 g (4oz) muffin	300	6	50	Exclude

The food nutrition facts are eigher on the packaging or you can do a quick search on a website like this one: http://www.fatsecret.com/calories-nutrition/ .

When you do your diet analysis you will be able to evaluate your foods, see how much total calories you are consuming and most importantly, how and where to cut down on your calories. Identify poor food sources, and put a note. That means that you will either have to abandon them or limit serving sizes.

You will have to do this table only for foods rich in calories, which includes all animal products, all flour and starch rich products, including grains, and all fat rich products. Green vegetables, salads and fruits are very poor in calories, so you do not have to include them in your analysis. Consume them in unlimited amounts in any combination.

When you have your custom food summary, follow these steps:

1. Determine you current calorie intake.Simply write out foods you have consumed yesterday and add up calories.
2. Adjust it according to your goal: weight loss, muscle gain or both. You will need to go down on calories a little bit in order to push your metabolism out of its stable weight zone into a weight loss zone. Use theses guideline for calorie adjustment:

• For most effective weight loss, reduce total calories to about 70% of your starting point.
• For most effective muscle gain, do not limit calories, stay at normal energy consumption.Substitute carbohydrate and fat with protein calories whenever possible.
• For a combination of fat loss and muscle gain go anywhere between 75 and 95 % of you starting point. The exact point will depend on many factors: your will power, eating habits, social habits, etc. To preserve or gain muscle, you absolutely have toexercise. If you do not exercise, you will lose both fat and muscle.

Example:

Meal	Calories	Protein
1 Potato, 4 oz pork, 15ml oil/salad	250+280+120=650	7+28+8=43
1 Potato, 2 eggs, 15ml oil/salad	250+70*2+120=510	7+12=19
120 g (4oz)Tuna in water	133	28
One 24oz can of light beer	200	—
2 cups (500mL) reduced fat milk	130*2=260	8*2=16
Total	1750	106

This 1750 calories, 106g protein diet would be a good weight loss starting point for many. As you can see, it is easy to design your customized diet which will also supply necessary amount of essential nutrients. No additional supplements were needed.Below are few more suggestions on healthy nutrition:

• Rely on what your body signals about its energy needs. Always be a little “hungry”. Do not indulge on food. Limit portion sizes and split food consumption evenly throughout day for best appetite control. When you exercise more the first thing that happens is that your appetite will increase. Watch your calories and do not indulge! Here is my article about managing your appetite.
• Do not attempt to starve and lose weight very fast. I do not recommend attempting to lose more than 2-3 kg (6 pounds) per week.
• Drink plenty of water. A lot of times you feel like you are hungry, but you are in fact thirsty. Drinking plenty of water fills up your stomach and helps reduce food cravings.
• Use two rules of legendary Mr. Jack Lalanne: “if man made it, don’t eat it”, and “if it tastes good, spit it out.”

In conclusion, I would like to mention that in a whole picture of health and fitness, your diet only comes second to physical activity and exercise. The importance of diet is overstressed, while physical activity and sleep regime in underestimated. The reason for this is simple – foods are easy to advertise and sell and require no effort on your side. And most people want something with no effort. That is why the market is flooded with all kind of nutrition and food supplement products that claim to “burn fat” with no effort required.

Some of these products are certainly good, but take any claims with healthy skepticism. Free-ranging eggs and vegetables from Whole Food stores are definitely better choices than regular products from cheap Mexican stores. But they will not do magic. You can lose weight with just diet, but you will lose both fat and muscle. And losing muscle means decrease in your body’s ability to burn food into energy. There will be very little or no gain to your overall health with just diet and no exercise.
