Eat less than half a loaf of bread or drink some milk in the morning (if you don't eat anything containing protein, it will be a waste to drink milk directly), or eat some fruit. You can eat normally at noon and eat some meat, but don't eat it every day. No dinner, nothing. Because people seldom exercise at night, the calories they eat are directly converted into fat. So skipping meals at night is the fastest way to lose weight. Absolutely not tired ~
