Why dieting and exercise do not lead to weight loss success

  Obesity has become a serious health problem, currently there are an estimated total of 671 million obese people worldwide, more than half live in the United States, China, India, Russia, Brazil, Mexico, Egypt, Germany, Pakistan, etc. It is expected that by 2035, the global diabetes population of 205 million, for the heavily obese friends almost all experienced the nightmare of dieting and exercise to lose weight, almost all Almost all internal medicine doctors will tell their obese patients to control their mouths and spread their legs. Almost all people think that weight gain is due to the fact that the calories consumed are greater than those consumed, and that to lose weight we must eat less and exercise more.  For obese people, diet and exercise will almost always reduce weight, but almost always will invariably rebound, so why diet and exercise can not lose weight successfully?  Dr. POKIN of the United States and other studies found that from 1977 to 2006, the average daily calorie intake per person increased by 570 calories, if calculated according to 1 pound of fat contains 3500 calories, if each person consumes 570 calories per day, the average person should gain 476 pounds. Of course our bodies do not, so are these increased calories due to our increased exercise resulting in increased consumption? Of course the truth is that from 1997 to 2006, people exercised less, so if you are following how many calories you consume and then how much exercise you do to burn the so-called calories, then 95.4% is a failure.  When your body needs calories but can’t get them after you work out, etc., it will choose to slow down its metabolism in order to consume less energy instead of converting fat in the body into energy through complex biochemical reactions. So eating less will only be our body to reduce consumption, not to help us reduce fat. At the same time, dieting for a long time, the body thinks that the famine is coming, will find ways to accumulate fat, muscle loss, the basal metabolic rate will slow down, so once the diet can not be maintained, even if it is just eating the same food as before, the body will think it is eating too much, the extra calories will be converted into fat storage, the result is that you are fatter than before. After a person has recovered from a famine, his body will find ways to store more fat in case of the next famine. The energy expended by exercise is often offset by the consequent increase in calorie intake, and each person’s metabolism has a tuning point, which is lower for those with a fast metabolism than for those with a slow heart sink metabolism. This point does not depend on the amount of calories consumed or consumed. Weight gain is the point at which the adjustment point rises, when the hormones of our metabolism change and the adjustment point of our weight rises.  Therefore, the lack of success in weight loss is not only due to the lack of human willpower, he has physiological reasons, so to lower the adjustment point and lose weight, it is important to eat the right food and choose the right exercise method. For obese patients, almost all have insulin resistance, that is, hyperinsulinemia, insulin is produced by the pancreas, which determines whether the body stores fat or burns fat, and glucose in the blood When glucose in the blood rises, the secretion of insulin increases and is used to absorb glucose. Too much glucose in the cells is converted into fat, and for obese patients, who eat too much, glucose in the blood rises quickly and the pancreas releases large amounts of insulin, leading to hyperinsulinemia. With too much insulin, the cells do not burn fat. With high insulin and more blood sugar, the effect of leptin is also affected, even though there is already a lot of fat, the person’s appetite is not affected and there is no desire to exercise, so the adjustment point of weight is raised.  The Chinese diet is also dominated by rice, noodles, steamed buns, etc. These foods are converted into calories very efficiently and will quickly increase the glucose content of the blood. Of course the emptying of these foods is also very fast, the feeling of fullness lasts for a short time, hunger will come quickly, and look for food to eat.  Some so-called weight loss tips say: sleep will also burn calories for weight loss purposes. Of course in our body has a basal metabolic rate, even lying still will have more than 1000 calories consumption, exercise, especially treadmill running exercise muscle group is very little, most of the muscles are treated as tired, so in running, the body will adapt to the loss of other muscles, so in many people running to adhere to a period of time later will find their other muscle wasting, body fat analysis found that the muscle content The body fat analysis shows that the muscle content has decreased and the fat content has increased. The loss of muscle instead represents a decrease in calorie consumption, because of the consumption of muscle. As we age, the body’s muscles gradually atrophy, and the reduction in activity accelerates the loss of muscle, so people after the age of 30 to 40 will find that their abdominal muscles are gradually disappearing, while the fat layer is thickening.  Chinese people have experienced thousands of years of hunger, so there is a “hunger gene” in the Chinese population, it is always monitoring your body’s caloric balance, once the wind blowing, will increase the absorption of calories and reserves, so in the Western research found that among the foreign population living in the United States, African-Americans and Chinese are more likely to obesity, which is related to The memory of hunger can be passed on to future generations through genes. The hunger gene is not only expressed in the absorption of calories, but also in the rapid reduction of energy expenditure when caloric intake is insufficient, i.e., a reduction in basal metabolic rate. Therefore, for Chinese people, eating less sometimes leads to faster obesity and more difficult diet control.  A large number of follow-up studies have shown that for patients with severe obesity either low-calorie diet or diet control plus exercise will reduce weight, but after 5 years, they will almost always regain weight, and as long as they lose weight once, rebound will occur, resulting in more and more weight loss.  Diet and exercise are ineffective for weight loss in patients with severe obesity and have been published by the American Dietetic Association. For patients with severe obesity, weight loss after surgery will reduce the patient’s caloric adjustment point, making the diet control easier and the hyperinsulinemia relieved. This leads to a long-term effect on weight control.
