It works for me. Been accidentally doing it since I was 13. Parents didn't give me an allowance, but they did give me lunch money, so if I wanted to buy games I had to skip lunch. Never went back and I've always been a healthy weight without much exercise.

Coffee for breakfast, water all day, and a double serving size of dinner. Lately, with the rising cost of food, I have been doing a lighter dinner and supplementing with a protein shake for lunch.
