Living a Fast-5 lifestyle means setting a window of five consecutive hours in which you do all your eating for the day. It doesn't mean binge eating or overeating. The long fasting period (19 hours) lets your body use stored fuel instead of fuel being delivered from digestion. That time also lets your body measure how much fat is stored and turn your appetite down if there's too much around. With a lower appetite, weight loss becomes easy." The Fast-5 Diet is available on line for free or as a book. There is a Facebook community experimenting with this life-style diet, as well as a forum. Both seem to be carefully monitored by the creator Bert W. Herring M. D.
He does have his detractors, like Alan Aragon, yet the muscle-building blogger world, and various testimonials, all seem to take much of what he says to heart and have applied variations in their own lives.
