Some people have a big appetite, but their bodies are still symmetrical and slim; And some people eat very little, but they still need to pay great attention to avoid horizontal development again. Has the gap between chubby fat people and slim thin people really widened in diet and exercise? Slimming has become an obsession of women all over the world, and the pursuit of thinness has surpassed the normal health scale. Of course, many people all over the world are suffering from obesity. They exercise hard and control their diet. The medical community has been committed to the research and treatment of obesity, but the effect is very small.

Scientists have recently discovered that an unhealthy diet does not necessarily lead to obesity, and genes play a greater role in health problems. The BBC once made a science and education film (why thin people are not fat). Gather together 10 thin people who claim that they are not fat, and order them to eat 5000 calories a day for four weeks and not exercise to see what will happen to their bodies. The experiment ended in four weeks. Experimental results: After four weeks of pure high-calorie gluttony experiment, thin people gained 8% weight, but the fat content changed little, almost all of them gained muscle, and the basal metabolic rate increased by 30%! . Experts who do experiments believe that this situation can only be explained by heredity and genes. The conclusion of the BBC experiment is that without human intervention (no conscious weight gain or weight loss), everyone's body will set an ideal value for their weight.

The order of influence on weight gain is gene > diet > exercise.

Genetic effects:

So far, genetic scientists have discovered at least 52 genes that may affect human weight. These genes can not only control eating, but also control the speed of metabolism. Genes not only determine whether you get fat easily, but also determine whether you prefer high-calorie foods. Scientists have discovered a gene called FTO. Adults with this gene are much heavier than others on average. The reason is that FTO patients eat more easily than others when they are not hungry. Thin people usually stop eating when they are full, and fat people continue to eat when they are full. The number of fat cells will increase sharply in adolescence, and no matter how you lose weight when you grow up, you can't reduce the number of cells. Therefore, if teenagers are fat, they will be fat all their lives.

So, how should we lose weight? In fact, everyone's body has a memory, and it will remember everything about you, including your eating habits, body shape, weight and so on. At the initial stage when you start trying to change, this kind of memory will help you restore your previous state.

Some people who don't eat fat may also have obesity genes, but they haven't met the right time yet. Similarly, some people who had the potential to stay in shape have become fat because of their acquired living habits.

Dietary attention: eat eight points full, less oil and salt, balanced and diverse.

Attention to exercise: Do aerobic exercise at least four times a week for one hour each time.

After all, a reasonable diet+persistent exercise is a lifetime thing!
