‘The Biggest Loser’ Update: Post Weight-Loss Program Results To Slower Metabolism

"The Biggest Loser" contestant Danny Cahill gained more weight than anyone on the show, losing 239 pounds in a period of seven months. The Season 8 contender who appeared in a knee-length shorts and a T-shirt, was looking very athletic, lean and handsome like a model weighing only 191 pounds in 2009.

Hearing the positive remarks from fans of the different parts of the world, his joy knew no boundaries. However, over 100 pounds have returned to his body frame size in spite all his attempts.

A study of "The Biggest Loser" contestants has revealed amazing new discoveries regarding the physiology of obesity, which can help understand why a number of people are not successful in their struggle to keep away from the weight they already lost,  Jezebel reported.

Scientist Kevin Hall, knew how to keep track of the show's contestants for six years following that triumphant night. The objective of the project was first to evaluate what happened to them over the period of six years following the lost of big amounts of weight, with the help of exercise and intensive diet program. 

Based on the findings, Dr. Hall noted the difficulty experienced by the body in order to fight back against the weight loss. One factor cited  is the metabolism, which controls the amount of calories burnt when a person is at rest. At the start of "The Biggest Loser," the contestants, while largely overweight, had average metabolisms, which means they have the average amount of calories burnt. When the show ended, the contestants' metabolisms had significantly slowed down and enough calories in their bodies were not burned to help them keep their thinner sizes.

"The Biggest Loser" the contestants' struggles explain the difficulty behind the continued fight against obesity, which affects a large number of American adults. In spite spending a large amount of dollars on  diet programs and weight-reduction drugs, even the most  determined ones work against their own body, according to News.
