Say a thousand words as long as the calorie intake is greater than the calorie consumption body will naturally get fat. An obese patient said: their family of three traveled to Shandong, because there are children they ordered 2 dishes and 1 soup, look at the neighboring table about 8-year-old child ordered their own 1 catty dumplings, they also added a copy of the same. When the dumplings were served, they realized that the amount was too large and hurriedly returned the one dish and one soup that were not served. As the family struggled to fix that portion of dumplings, the kids at the neighboring table had already finished eating and settled the bill. When I say that some fat people eat a lot, they will feel quite wrong because they obviously do not eat more than some thin people, but their weight is much higher than them. These fat friends absorption capacity is naturally better than normal people, if the normal people with the standard of diet eating, it may cause caloric surplus. Now we are talking more about the principle of one more bite, one more bite at each meal, and slowly getting fatter over time. Talking to many weight loss patients, I found that they may not usually have such an amazing amount of food, but they often crave it, and even have sweaty palms, panic attacks, and short tempers. It is hard to put down the chopsticks when eating their favorite food. When full they realize they have eaten a few more bites. Their fat accumulates in dribs and drabs like this. When communicating with the patients, it was also found that most of the weight loss patients had a phase of rapid weight gain. (e.g., after having a baby, metabolic levels dropping, athletes retiring, broken bones and injuries, etc…) During these phases calorie consumption is significantly reduced, while the diet is not controlled in time, resulting in a sudden weight gain “fat out of the new height”. When they realize that they need to lose weight, they find that obesity has become a burden to them, and that increasing the amount of exercise can be particularly tiring and weighing the joints can be overwhelming. And years of eating habits can not be changed. Such a vicious cycle can only watch the weight gradually increase. When the weight gain is found, if you change your eating style or lifestyle habits in time. Maybe the future will not be plagued by obesity. Weight loss surgery is also the most helpless choice, although the surgery can control solid calorie intake, while improving hormone regulation, greatly reducing the secretion of hunger hormone. Also just to give the patient thin down the state, if of the trust in the surgery, and rest assured that eating and drinking, the weight will certainly one day will rebound. Only healthy eating habits, green lifestyle is away from obesity lifelong protection.
