I can only give you some advice on slimming, all of which are my years of experience. I think you can consider selectively giving up drinking and eating something to lose weight, instead of always skipping dinner. For example, high-fat foods (animal viscera, and meat that grows in less active parts of animals, such as chicken breast, pork belly and duck breast) are very high in fat and have no nutrition. There are also starchy foods, which are more difficult for boys to quit. My neighbor, a chubby kid, can run with great perseverance every day, but he just can't help eating. . . So I still can't lose weight.
You can consume about 1800 calories a day. During the period of losing weight, you can control your food intake to 1200 calories a day. In this case, in order to be addicted, it is better to eat something with low calorie. And healthy. Like vegetables and fruits,100g has about 30 calories to 150 calories, so you can eat a lot, and you won't get fat when you are full. Fish and rabbit meat in meat have the lowest calories and much higher protein content, so they can be eaten in moderation during weight loss. Milk and eggs should also be supplemented in moderation every day, about 250 grams of milk and 2 eggs. When choosing cooking methods, you should also be careful not to eat too much frying and frying oil. Don't eat fish-flavored eggplant and the like, that bite of eggplant is a bite of oil. . .
Things like rice and noodles are high in calories, but not very nutritious. If people with heavy physical or mental work need it, if not, you can quit completely. I have given up smoking for several years and am in good health. Should I eat delicious food or should I eat it? It has always been about 90 kg (I am 160CM). Starch removal is very effective and painless. There is nothing delicious about rice.
Also, alcohol will cause the fat you ingest that day to be directly stored in your body, which is a big taboo to lose weight, so you must quit. Especially spirits, shochu, whisky and vodka. And beer itself is high in calories (liquid bread), so don't drink too much!
Drink plenty of water, especially after getting up early. Drinking a large glass of boiled water is good for your stomach.
