Last summer, I was a practitioner of the 2 1 day diet. I have persisted for a long time, and the effect can not be underestimated, but the degree of rebound is also amazing! First of all, I think it is really difficult to do it if it is strictly implemented. Since you are fat, the reason for being fat must be that you are not hungry, love to eat and can eat very much, but a diet of 2 1 day is to completely resist the feeling of starvation. I persisted for three days and stayed in dream of eating all night. It feels painful! One more thing, I was in a bad mood because I was hungry. It makes sense that food is the most important thing for people. You can lose a few pounds after a period of persistence, but when you are hungry to the limit, you will continue to fill your stomach, and then your weight will rebound to be fatter than before. I did watch Li Zhenni's Seven-Year History of Fighting Meat: The Transition from 130 to 90 Jin. Behind this article is the blogger. At present, it has persisted for six days and the effect is not bad. I don't know if it will be useful to you.
