You can eat, but you can't eat after snacks. I used to want to eat potato chips when I lost weight. Basically, I ate two packs of potato chips at night and didn't eat dinner. I never avoid eating French fries, biscuits and dairy products. As long as you don't eat dinner, you can eat snacks again. You lost more than 20 kilograms in one semester. I am the kind of system that makes me fat after drinking water, so don't be afraid. My experience is very successful.
