How Not to Diet

The book "How Not to Diet" by Dr. Michael Greger offers a new perspective on the issue of weight loss and healthy living. Instead of drastic diets and short-term solutions, he focuses on long-term strategies that are scientifically sound and sustainable. Known for his emphasis on evidence-based nutrition, Dr. Greger leads readers down a path of small but effective changes that produce real results. The book isn't just about weight loss; it's a comprehensive guide to health that touches on all aspects of our lives-from eating habits and physical activity to sleep and mental well-being. Through 21 tips, the author offers a realistic and practical approach to achieving and maintaining a healthy weight without extreme restriction or calorie counting. Readers will learn how to easily and gradually implement this advice into their daily lives.

This approach is backed by numerous scientific studies that suggest that plant-based meals not only provide plenty of nutrients, but also promote satiety and reduce overall calorie intake. In practice, this means that foods like beans, vegetables, fruits and whole grains fill us up without unnecessarily burdening the body with excessive fat and empty calories. In addition, a plant-based diet has a very positive effect on heart health, digestion and blood pressure. One example we can cite is the historical case of the so-called 'Blue Zones' - areas where people are living to a significantly older age thanks to traditional diets. One of these areas is the island of Okinawa in Japan, where locals mainly consume vegetables, seaweed and soy products. Okinawans are known for their low incidence of heart disease and cancer, and their diet is a prime example of how a plant-based diet can help us not only in length but also in quality of life. Another aspect that needs to be highlighted is that plant foods are high in fibre. Fibre has the ability to slow down digestion, which helps keep blood sugar levels stable while prolonging satiety. This can be especially helpful for people who are struggling to manage cravings and overeating. Since fiber is only found in plant foods, switching to a diet rich in these sources is the key to losing weight without experiencing constant hunger. However, switching to a plant-based diet does not mean that we have to completely eliminate all animal products. Rather, it is about changing the ratio of foods on the plate. When more vegetables, legumes and whole grains are on our plate, our bodies naturally begin to adapt to healthier options that fill them up with fewer calories. Today, a growing number of people are turning to this form of eating not only for their own health, but also for the sake of ecology and sustainability. Many studies show that plant-based food production has a significantly lower environmental impact than animal production. In terms of both personal health and societal benefits, a plant-based diet therefore appears to be a pathway to sustainable health and a better future. So if you are looking for an effective way to achieve and maintain an optimal weight, a plant-based diet may be a solution that will surprise you with its positive effects not only on weight but also on overall health.

This idea means that we prefer foods that contain fewer calories per gram, allowing us to indulge in larger portions without increasing our calorie intake. For people who are trying to shed excess pounds, this is a very effective way to feel full and satisfied while gradually reducing their weight. Imagine, for example, a classic fast food meal such as a burger and fries. While these foods are tasty, they are also very calorie dense. Just a few bites can contain hundreds of calories that the body can't burn quickly, leading to weight gain. Conversely, a serving of salad with colorful vegetables and low-calorie dressing is low in calorie density and can be larger, so it makes us feel full, but without the risk of increased energy intake. It is also important to know that foods with a lower calorie density are often high in water and fiber. For example, watermelon, cucumber or broccoli are great examples of high water content foods. This makes them filling because they add volume to the stomach, but with only a minimal amount of calories. This allows us to eat large enough portions to feel satisfied without worrying about weight gain. Researchers have found that people tend to consume about the same amount of food each day based on volume, not calories. This means that if we choose foods with a lower calorie density, we will automatically reduce our daily calorie intake, which will help us reach our weight goals without constantly restricting ourselves. Various studies suggest that a low-calorie density diet may also have positive effects on long-term health, including a reduced risk of chronic diseases such as diabetes and heart disease. Moreover, this eating philosophy is not about giving up food, but about making more thoughtful choices that benefit our bodies and minds. For those trying to change their eating habits, this approach can be refreshing and less stressful than traditional diet plans, which often require strict calorie counting and portion restriction. A diet based on low calorie density offers a great way to achieve and maintain a healthy weight while enjoying generous portions of varied and delicious foods.

It is these ingredients, often hidden in processed foods, that are the main source of 'empty calories', which provide us with few nutrients but lots of energy. To achieve and maintain a healthy weight, it is therefore helpful to limit these 'extra' ingredients. Many people may not even realise how much added sugars and fats they consume on a daily basis. For example, beverages such as sodas and flavored coffees contain large amounts of sugar that immediately enter the bloodstream, causing a spike in sugar levels and a subsequent drop that triggers feelings of fatigue and additional cravings for sweets. This cycle not only leads to excess weight, but can also contribute to insulin resistance or diabetes over time. Another example is fast food and industrially processed snacks, which are often saturated with added fats, especially saturated and trans fats. These fats not only increase caloric intake, but also have a negative impact on heart and vascular health by contributing to higher levels of bad cholesterol. By avoiding such foods, we can reduce our risk of cardiovascular disease while keeping our weight under control. Limiting added fats and sugars doesn't mean we have to cut all fats and sweets out of our diet. Instead, it's about prioritising healthier alternatives such as the healthy fats found in nuts, avocados and olive oil, and naturally sweet foods such as fruit. In this way, we get the nutrients we need into our bodies while limiting empty calories, which, although they may fill us up for a short period of time, do not give us any long-term sense of satisfaction. Studies show that limiting added fats and sugars can be an effective way to reduce caloric intake without feeling hungry. Instead of sugar in coffee, we can try cinnamon, which has a natural sweet taste, or replace ice cream with frozen fruit to refresh and satiate us. Even small steps, such as choosing foods with less added fats and sugars, can have a big impact on our health and weight. This approach encourages us to be mindful of food composition and make conscious choices that will benefit our long-term health.

The gut microbiome is like a small ecosystem community that houses trillions of bacteria and other microorganisms that play a vital role in digestion, immunity, and even weight management. The gut microbiome influences not only how efficiently our body processes food, but also how it can utilize nutrients. Research suggests that people with a more diverse microbiome, those who have a greater number of different types of bacteria in their gut, have a better ability to metabolize fats and maintain a stable weight. Conversely, low microbiome diversity is associated with risk of obesity and other metabolic diseases. One way to support a healthy microbiome is to consume prebiotics and probiotics. Prebiotics, such as fiber from whole grains, bananas, and garlic, provide nutrients for beneficial bacteria in the gut. Probiotics, found in yoghurt, kefir and fermented foods such as sauerkraut and kimchi, in turn contain live cultures that can enrich the gut flora with beneficial bacteria. Some experts even suggest that our mood and feelings of hunger may also be influenced by chemical signals sent by bacteria in the gut. For example, bacteria that thrive on eating sugary foods can signal the body to crave sugar, thus promoting addictive cravings. However, a healthy microbiome can regulate these signals, which can help in managing cravings for unhealthy foods. Prolonged consumption of processed foods and unhealthy fats can upset the balance of the microbiome and encourage the growth of harmful bacteria. Therefore, if we want to optimise gut health, we should choose a varied and balanced diet rich in natural and minimally processed foods. A healthy gut microbiome will not only help with digestion and weight management, but will also improve our immune system and overall well-being. Thus, this microbiome care is not just a fashion trend, but an important step towards overall health and successful weight management.

This idea focuses on the use of chronobiology in eating, that is, adapting foods to our body's biological rhythms. This approach is based on research showing that our bodies process calories and nutrients more efficiently at certain times of the day, which means that the timing of meals can have an impact on how we feel and how we manage our weight. A simple example is the well-known concept of "breakfast king and evening leanness," which recommends a richer breakfast and a lighter dinner. Studies show that meals eaten in the morning and mid-morning are more efficiently processed for energy, while evening calories are more likely to be stored as fat. For those trying to lose weight, it is therefore advisable to eat main meals earlier in the day and keep dinner lighter. Morning meals are also important because they help to stabilise blood sugar levels, which will give us energy for the day and also reduce the risk of sudden cravings for sweets or overeating later in the day. People who eat breakfast regularly often have a lower total daily calorie intake because their bodies manage hunger and satiety more effectively. However, meal timing doesn't just apply to breakfast and dinner. There is also research on the so-called 'eating window', where it is recommended to limit eating to a certain number of hours during the day - for example, between eight in the morning and six in the evening. This approach, known as time-restricted eating, is a form of intermittent fasting that has a positive effect on metabolism because it allows the body a longer period of rest from digestion. Chronobiology also applies to sleep, which has a direct impact on our eating habits. Lack of sleep can disrupt hunger-regulating hormones such as leptin and ghrelin, leading to increased feelings of hunger and cravings for calorie-dense foods. So, if we want to take advantage of our body's rhythms, it's important not only to time meals properly, but also to ensure we get enough quality sleep. This approach not only helps with weight loss, but also promotes overall health as it focuses on the body's natural biological rhythms. Chronobiology is therefore not only an interesting scientific concept, but also an effective tool for those looking for long-term and sustainable ways to improve their health and keep their weight under control.

In fact, movement not only burns calories, but also stimulates metabolism, promotes muscle maintenance and has many other health benefits that motivate us to stay active. One of the main benefits of exercise is an increase in basal metabolic output - that is, the amount of calories the body burns at rest. Muscle mass actually requires more energy to maintain than fat tissue, so the more muscle we have, the more calories we burn at rest. For those who are trying to lose weight, it is therefore ideal to include strength training in your exercise plan, whether in the form of weight training or exercises with your own weight. Aerobic activity, such as running, cycling or swimming, is equally important as it effectively burns calories and promotes heart health. These activities increase lung capacity, improve blood circulation and help the body use oxygen more efficiently, which has a positive effect on overall health and stamina. For example, studies show that regular running can reduce the risk of heart disease and improve mood, which is a benefit for those facing the stress associated with lifestyle change. For many people, exercise is also a way to cope with emotional overeating. Physical activity stimulates the production of endorphins, known as "happiness hormones," which improve mood and help manage stress. Regular exercise can therefore serve as a healthy substitute for unhealthy food habits that bring us only temporary pleasure. The benefits of exercise for sleep quality should not be forgotten either. Exercise during the day promotes deep sleep, which is important for the body's recovery and for hormonal balance. Quality sleep also affects the levels of hormones that regulate hunger and appetite, which means that a well-rested body is better equipped to handle the urge to overeat. Although physical activity is an important part of a healthy lifestyle, there's no need to set unrealistic goals right away. If a person is not used to exercising regularly, just start with short walks or lighter exercise that gradually increases stamina and strength. The important thing is to maintain regularity, as this is what helps to create a long-term habit and maintain the results. Ultimately, regular exercise becomes a key pillar not only for weight loss, but also for maintaining a healthy weight and physical and mental health in the long term.

Hydration is a cornerstone not only for proper metabolic functioning, but also for hunger control and weight management. Insufficient water intake can lead to confusion in the body's signals when hunger is mistaken for thirst, often leading to overeating and unplanned snacking. Water has many functions that support health and weight loss. For example, it aids in digestion by facilitating the movement of food through the digestive tract and ensuring better absorption of nutrients. When we drink enough, our bodies are able to process food more quickly, which means burning calories can be more efficient. Studies also suggest that drinking a glass of water before a meal can help reduce hunger and overall food intake during a meal. Another benefit of adequate hydration is improved energy levels and concentration. Even mild dehydration can affect our cognitive abilities and cause fatigue, which can lead to us reaching for calorie-dense snacks as a quick source of energy. When properly hydrated, we feel more alert, which can help manage the urge for junk food. Some experts also recommend including unsweetened teas or lemon water in your daily drinking regime, which provide the body with antioxidants and are low in calories. Such drinks can be a tasty and healthy alternative to sweetened beverages that contribute to weight gain. For example, green tea is known for its thermogenic effects that stimulate fat burning and boost metabolism. On the other hand, drinking sugary drinks such as sodas or flavored juices can have the opposite effect. These beverages contain large amounts of hidden sugar and calories that are quickly absorbed into the bloodstream, increase insulin levels, and can promote fat storage. People who have trouble keeping track of their water intake can use simple tricks such as apps to track their drinking or carrying a water bottle with them at all times. Research shows that drinking water regularly can help with weight management and promote overall health, as hydration improves skin quality, supports kidney function and contributes to feelings of vitality. Adequate water intake is a simple yet effective way to help the body function optimally, feel better and manage weight control effectively.

Sleep is an often underestimated factor that directly affects the levels of hormones that control hunger and satiety, as well as the body's overall metabolic activity. Lack of sleep can result in hormonal imbalances, which can lead to overeating and weight gain. One of the key hormones affected by sleep deprivation is ghrelin, which stimulates the feeling of hunger. When we are sleep deprived, its levels rise, causing us to feel hungrier during the day and tend to reach for foods high in sugars and fats. On the other hand, leptin - the hormone that signals satiety - is lower when we're sleep-deprived, meaning we don't feel as full as we should after eating. In addition to hormonal regulation, sleep deprivation can also affect our ability to make healthy choices. When we're tired, we have less control over impulsive behavior and are more likely to reach for unhealthy foods as a quick source of energy. This effect often occurs especially in the evening when we are more tired and crave calorie-dense foods. Sleep also affects metabolism, specifically the body's ability to process glucose efficiently. Research suggests that sleep deprivation can reduce insulin sensitivity, leading to higher blood sugar levels and an increased risk of metabolic diseases such as diabetes. Adequate sleep is therefore crucial not only for maintaining a healthy weight, but also for preventing chronic disease. A healthy sleep schedule also involves regularity - ideally, going to bed and getting up at the same time every day helps the body adjust its biological rhythms. These rhythms affect not only the quality of sleep, but also the body's ability to function efficiently during the day. Many experts also recommend creating an "evening routine" to help us prepare for quality sleep. Avoiding electronic devices such as phones and computers for at least an hour before bedtime, and engaging in calming activities such as reading or meditation, can contribute significantly to deep and restorative sleep. Getting enough quality sleep is thus not just about rest, but has a direct impact on the body's ability to maintain a healthy weight, control cravings and manage stress. Sleep is therefore an important tool in the journey towards a healthier body and mind.
