Dieting, not eating food containing starch, sucrose and fat for the first three days, giving yourself psychological hints to re-adapt and enjoy hunger.

Then the staple food at noon is coarse grains, and the food is low in calories. If you are greedy, you can eat fruit, but you can't eat too much. Diet soda can also relieve appetite.

Without strict adherence, I lost 20 pounds in two months.
