All these things about extending your life I find are hard to confirm. I mean the whole point of breakfast is for breaking a fast the lasted already about 10-12 hours? How can it be possibly healthy to extend that to 18 hours, and not have anything in between? You'll constantly be lethargic and tired. I did one of those diets for 3 weeks, no eating in between meals, and living on rabbit food for lunch (tomato, cucumber, carrots, bake beans) and dinner (garden salad), and only having a small portion of corn flakes for breakfast... sure I lost 10 kgs but I wanted to end myself.
