What method of losing weight is cheap, effective and short?

I tell you from personal experience that losing weight depends on products, which wastes life and money and has no effect. /kloc-when I was 0/8 years old, I gained a lot of weight because of overeating with my classmates at school. At that time, I used all kinds of slimming products, from tens of dollars of slimming tea to hundreds of dollars of Qumei, and secretly ate several boxes behind my parents' backs, which did great harm to my stomach, liver and kidney. I was still very active at school at that time. I play ball every day and sweat like rain, but I still can't lose weight. Later, I gave up losing weight. After graduation, I worked and ate at home and gradually lost weight. If you want to lose weight, you'd better do the following: 1, drink plenty of water, only drink boiled water at any time, and take a sealed cup with boiled water when you go out. If you need to buy water, buy mineral water, and don't drink any other water, including carbonated drinks such as Sprite and Coke, various fruit juice drinks, yogurt and dairy products. ~ the details only need to look at the ingredients on the beverage package, as long as it contains artificial additives. 2. In addition to drinking more boiled water every day, eat more fresh fruits in the local season, depending on personal preferences ~ ~ I personally eat at least 1 apple every day, usually around 10 in the morning. I still want to eat fruit around 3 pm. There are pears to eat, and melons to eat. I never shy away from fruit. 3. Except fruit, other snacks are basically not eaten. If you really want to eat snacks, knock melon seeds or eat walnuts. Three meals regularly, cooking at home. One meal, you can cook 1-2 vegetarian dishes, the same meat dishes. Vegetarian dishes can stutter, and there are no taboos. You can't be greedy for meat dishes, but you can eat enough ~ don't eat enough ~ drink yogurt 2 hours after dinner, just a small cup. Don't sit at home and watch TV after dinner. After half an hour's rest, go out for a walk. It takes 20 minutes to walk 1.6 km, which is equivalent to walking four times on the school 400-meter runway. Remember to walk in 20 minutes at a speed of 5 minutes. This is not only easy to consume calories, but also won't be sore after crossing the hind legs, which is conducive to persisting in exercise. Usually you don't need to run, and you don't need any big physical exercise, so your body is prone to soreness and fatigue, but it is not very beneficial to your health. After walking, the body has been promoting blood circulation. You can do a full-body stretching: broadening your chest, stretching your legs, doing aerobics, etc., depending on your personal hobbies, as long as it is an activity. All of the above are actually easy to do. As long as you have willpower and form a habit, you will find that losing weight is not the end, and a healthy and happy life is still our ultimate goal.
