First, you should drink more water. Drinking before meals is good for your stomach. Drinking a cup half an hour after a meal will wash away greasy food. Anyway, drink it if you have nothing to do. Secondly, it is very important to chew slowly when eating. Eat more vegetables and eat less. Have dinner early, around five o'clock. You can drink porridge. If you are not used to it, eat more vegetables. Remember, be sure to have breakfast! Also, try to stand and sit for a while. When sitting, keep your waist straight, and with some small exercise, you can do it at home. You can check it online. There are many, so we must stick to them. When you get used to it, it means that you are keeping it, so you will lose 5 or 6 pounds in the fastest week. I used to do this.
