I used to eat a big bowl of soup like Pho (Vietnamese beef noodle soup) at 11 pm. When I realize how much weight I put on over time. I try to eliminate it.
1. I try to go to bed early
2. I was starved at night for 1 week
Then I get used to it. Now I try not to eat after 7pm as much as I can. Of course, some time I have to break that rule and I end up over eating (I have 2 dinners), my regular dinner around 6pm, then social dinner like at my family in law, or friends.
