A cookbook, also known as a cookbook, is a document or book that teaches people to cook food. Generally, it is a book or manual on daily diet, with information such as cooking formula, cooking steps and skills. After scientific analysis, according to the category or system of an object, it is edited into tables or other neat forms for reference.

Four principles should be mastered in diet.

1, balanced nutrition, fixed time, establish a good habit of three meals a day: the most efficient way to lose weight is to eat three meals a day, regularly and quantitatively. You can choose carbohydrates that can be converted into energy in the morning, protein that can be used by body cells at night, and don't eat for two hours before going to bed.

2. Pay attention to the choice of main course and side dishes: if the main course uses more oil, the side dishes are best boiled or scalded. On the contrary, if the main course does not contain fat, then the side dishes with a little fat are harmless. If you don't pay attention to the collocation of the main course and the side dishes, you may accidentally consume too much fat.

3. Understand the calories of staple food: Compared with bread, rice and Qiao Mai noodles are better choices. Especially rice, eaten slowly, can prolong the eating time and increase satiety.

4. Drinks are often the death point of losing weight. It is important to note that during weight loss, drinks must be sugar-free and cream-free, and it is best not to drink fruit juice. Use water and tea to replenish water. Of course, high-calorie alcoholic beverages must also be avoided.
