I didn't eat lunch for just two months today, and I lost about 20 pounds, mainly because I didn't exercise much. I just turned the hula hoop every day! Boys recommend jogging.
The method of not eating after noon is mainly to eat full in the morning and noon, and not to eat after two in the afternoon. You can drink it with Pu 'er tea, which is very effective for slimming! It's not a diet tea, so don't worry about negative effects!
They say that if you stick around, you will form or change a habit. I think I have formed the habit of skipping dinner now. Believe in yourself, you can do it!
