I have a plan to gain weight, which will relieve your pain. I'm sure you will like it. A bottle of yogurt before breakfast every day can promote gastrointestinal digestion, increase gastric motility and stimulate appetite. Eat it half an hour later, so that the food can be fully digested and absorbed in the stomach that has just been replenished with energy. At noon, I am drinking a bottle of milk. Milk is a high-fat and high-protein food, and its nutrition is relatively richer. If you persist in this way, 15 days will change. Convenient, fast and effective. Just try it. My brother used it. It worked!
