Eat as little staple food as possible, and the amount of staple food per meal should be less than 2 taels (i.e. eat less pasta, and the amount of staple food such as rice and flour should not exceed half a catty per day). It is best not to drink rice porridge in the morning, you can use milk instead.

c. Limit the amount of fruit, especially those with high sugar content (change fruits such as kiwi, cucumber, and tomato, which are not high in sugar. Eat them between meals). Do not eat eggs at dinner.

d. Eat more vegetables, no less than 500 grams per day, to supplement vitamins and fiber.

e. Drink plenty of water and exercise moderately. Take a walk after meals to consume excess sugar.
