Eating just one meal a day is popular among health conscious people and you can find a lot about it on the Internet.
Bottom line: It's enough to keep you fueled, it teaches your body to burn fat and not live on sugar, and, perhaps most important, it gives you digestive system and the rest of your body a rest.
Eating one meal a day is how people used to eat hundreds of years ago - until the marketers got a hold of breakfast.
Who were these marketers? Some pretty twisted people.
