[Pay attention to carbohydrate intake] After 4 p.m., avoid consuming carbohydrates from staple foods, such as rice, pasta or potatoes. These foods tend to accumulate fat in the abdomen, but you can enjoy a hearty dinner just like enjoying Great breakfast as well as lunch. Have a dinner rule, such as protein-rich seared tuna, plus a fruit or vegetable salad. In this way, when you wake up the next morning, you will never worry about gaining weight in bed yesterday.
