Hello. Green balls are not low in calories and need to be eaten in moderation. It is best to eat only one a day. Not eating at night can effectively avoid increasing the burden on the stomach and fat accumulation. After eating green balls, you'd better eat some food that helps digestion, such as hawthorn. Don't eat green balls when they are cold, which can avoid fat accumulation caused by long-term indigestion of glutinous rice. Also, cold green ball, blood sugar rises quickly, which is easy to cause blood sugar to rise. Eating green balls is afraid of gaining weight, so it is better to strengthen exercise, which can help metabolism. Therefore, if dieters like to eat green balls, they must pay attention to increasing exercise time and have calorie metabolism to avoid getting fat. I wish you all the best, health, happiness and happiness. Please adopt it. Thank you.
