Basic calorie calculation formula: daily calorie required by adults = basic calorie required for basic metabolism of human body+calorie required for physical activity+calorie required for digesting food. Heat required for digesting food = 10% x (minimum heat required for basic metabolism of human body+heat required for physical activity).

Several high-calorie foods

Sugar content of raisins: 1 cup gram. Although most of the dried fruits are natural sugar in grapes, some factories will add extra sugar to improve the taste and flavor because of the dried fruits. And raisins, like snacks, can be added with many cooking ingredients, so you will unconsciously eat a lot and have high calories. Eating 1 cup (170 g) of sugar is already higher than McDonald's ice cream (g).

Sweet and sour chicken: grams. Sweet and sour chicken is a delicious Chinese dish, but the thick seasoning makes its sugar content three times higher than that recommended by WHO. McDonald's gives people the impression that the sugar content of sweet chocolate milkshake is grams, but a home-cooked sweet and sour chicken is higher than it.
