I have been eating once a day most of my life :) Never was hungry till about 3-4pm everyday. When I was a kid I used to eat breakfast lunch an dinner until I was a teen, basically. If I ever do eat more then once a day I will nibble on things throughout the day, a few peanuts, maybe a couple raisins, etc. Plus I drink coffee in the morning. Drink a lot of water and you will never really get hungry. I probably drink a gallon a day. Intermittent Fasting.
