So to prove it he ate a diet of Twinkies, powdered donuts, Doritos chips, sugary cereals and Oreos every 3 hours - and no regular meals at all. After 10 weeks he had lost 27 lbs.
How? He limited himself to 1800 calories - but he had been husky, eating about 2,600 calories per day and after eating less his BMI went from 28.8, overweight, to 24.9, normal, and he is now down to 174 pounds.
Like the Atkins Diet or other shock weight loss regimens, it isn't good over the long haul but any time you eat less and cause your body to readjust to new dietary habits, you will lose weight.
Maybe he should write a book too.
