The first thing I want to answer you is that always thinking about eating is a neurological hobby, which is mainly controlled by hormones in the body. At the same time, genetically it is the expression of a certain gene, but it can be controlled the day after tomorrow. You need to find something. For other things you are interested in, if you exercise restraint, you can improve within a week. (As a reminder, eat snacks in moderation. Religion says that desire should be the result of long-term stimulation, which is a bit like a biological conditioned reflex. You eat snacks many times. Delicious snacks will continue to stimulate your nerves and produce desire, so it will become more and more uncontrollable. If the purpose of eating is to fill your stomach, there will be a change in your mind. Give it a try)

P. Two questions: You are wrong when you say you can't digest it. If you can't digest it, your stomach will remind you, such as bloating and discomfort, acid reflux and other physiological reactions. If you still feel refreshed after eating those things, and after a while If you are still hungry, it proves that you have excessive secretion of growth hormone, insulin and other hormones. You can go to the hospital for a check-up. The food you eat will decompose and synthesize necessary amino acids and then protein. People need a lot of protein every day, and these The process requires energy. People who eat normally and exercise moderately every day will have very little fat storage. If they eat too much and lack exercise, the amount of fat stored will increase exponentially.

The third question: Diarrhea is caused by illness, intestinal infection or food poisoning. During excretion, some calories and intestinal juice will be taken away, but the consumption of fat is the substance and substance needed for subsequent intestinal repair. Energy is like building a house. If the house breaks down, use the nearest materials to repair it. Fat is the nearest material. However, I personally do not recommend using this method to lose fat.

This is of course not a professional answer, please forgive me for any inappropriateness
