1. Take passive exercise and avoid active exercise, which can not only consume arm heat, but also avoid stimulating arm muscles. For example, ask your partner to help you move your upper limbs, or exercise your upper limbs without weight.

2. The canteen doesn't eat greasy cooking and cakes. You can eat steamed bread and rice as much as possible, not to mention vegetables and fruits, and you can also eat a little meat, eggs and milk.

3. Doing more lower limb exercises can make the blood nourish the lower limbs, thus reducing and inhibiting the weight gain of the upper limbs. At the same time, if the lower limbs are strong, running upstairs will not be very tired, and people will not become lazy and fat easily.
