I've never heard of this, but there are ways to lose weight:

If the boy's waist is thicker, you can lose waist fat through exercise.

Drink less beer to avoid bloating. Exercise is similar to the following one, specializing in reducing waist meat.

You can pinch YIXOYU at your waist in advance to heat it up (both men and women can).

Step 1: Lie on your back, tighten your hips, and keep your feet shoulder width apart;

Step2: Leg tips close to the inside, hands crossed behind the head;

Step3: inhale, lift your legs up, 5 cm from the ground, and straighten your toes;

Step4: Hold the head with both hands and stretch the neck; Hold action 10 second;

Step 5: Exhale, restore the original posture, and repeat 10 times.

Set aside some time to do this several times a day to help you lose weight.
