No effect, of course, no side effects. I haven't eaten yet, and I'm trying to lose weight now. I lost 8 Jin a month! Pretty good! The other one is called flower fiber bone, which is good and made by reasonable diet. I read about this method in Zhou Xinlei's diary. For example, yesterday's breakfast: 1 boiled eggs, cooked at night, not in a hurry the next day, and then 3 slices of whole wheat bread in the morning, 1 cup of milk, 3 walnuts and 2 red dates! Lunch: fish, two kinds of vegetables, I ordered takeout, and then 1 bowl of rice! Come to an apple in the afternoon to prevent hunger at dinner. Eat at night: 65438+ 0 to 2 portions of stir-fry, sweet potato 1 piece, 6 steamed shrimps! No rice for dinner! Use coarse grains instead! As the saying goes, "Eat well in the morning, eat well at noon and eat less at night" is one aspect, and the balance of diet also needs attention.
