Did you use a diet but despite an initial success, after it is finished, the weight returns to the starting point? It is frustrating but often it is not your fault that the diet does not work.
How much you weigh strongly depends on how much you eat and how much energy you burn. When we use the diet we put the brain into hunger mode. The hypothalamus is part of the brain that regulates body mass. The system works like a thermostat, responding to body signals and adjusting hunger, activity and metabolism to keep your weight stable with changing conditions. The brain responds to weight loss and tries to bring our body back to what it considers normal. Stress hormones act on fat cells. Slimming often causes later overeating and weight gain. In other words, the diet may be exactly opposite to what it should do. Almost all diets are “yo-yo” ones: you lose weight and you will always come back to the initial one. Of course, if you drastically lower your calorie intake in a short time, you will lose weight. However, this is not permanent and often results in increased weight. If you lose a lot of weight, your brain will react as if you were starving. It makes sense from an evolutionary perspective. When food was rare, our ancestors had to save energy to survive. Our bodies are simply not designed to lose weight, but keep them to survive.
Eat carefully. Then you learn to recognize the signals of your body, so that you eat when you are hungry and stop eating when you are full. People who focus on their hunger have a lower chance of being overweight and spend less time thinking about food. Those who try to use their will power are more susceptible to overeating.
