Yo-yo dieting theory vs. Sponge Theory
as cause of easy weight regain in reduced obese.
The Diet Fix by Yoni Freedhoff, MD
Myths, presumptions and facts of obesity
Frank Greenway writes about the new science validated in
The Biggest Loser experiment
1- Body Mass Index:48.7 ± 10.1 kg/m2
2- Weight 144.9 ± 39.4 kg, and
3---Body Fat 49 ± 6% (mean ± SD)
During the first phase of the competition when the contestants were isolated in a boot camp environment,
the average rate of weight loss was 0.4 ± 0.1 kg/d and
decreased to 0.19 ± 0.1 kg/d after returning home.
Total weight loss was 58.2 ± 26 kg with
81.6 ± 8.4% coming from body fat.
The computer simulations closely matched these data and calculated that average energy intake decreased by 65% during the first phase to 1300 kcal/d while participating in 3.1 h/d of vigorous exercise.
After returning home, energy intake increased to 1900 kcal/d and vigorous exercise decreased to 1.1 h/d.
Simulation of diet alone resulted in 34 kg of weight loss with 65% coming from body fat,
whereas exercise alone resulted in a loss of 27 kg with 102% from fat.
