Breakfast: an egg, a bowl of porridge, a small dish of pickles (people with light taste can't eat pickles) or a steamed stuffed bun and a cup of soybean milk (preferably sugar-free)
Lunch: cold dishes (I'll add some vinegar)
Fruits (such as apples or other low-calorie fruits)
Dinner: fruit or cucumber or tomato
Note: Don't drink water after 6 pm, especially MM who loves edema. No matter how much you eat, don't sit right after eating. Get up early with a cup of warm water.
Exercise: Hula hoop lasts 30 minutes at a time (or 20 minutes in the morning and evening). Stick to an exercise for 30 minutes, and do soft exercises on the parts that want to lose weight or gain weight. Persistence is bound to succeed.
