“Pretty much every contestant on “Biggest Loser” gained the weight back because calorie restriction destroyed their base metabolism and they could not maintain the level of exercise required and hold down a job, care for a family, etc.”
They gained it back because they consumed more calories than they expended.
It would be impossible for there to be another cause.
It’s a binary and absolute axiom.
to say otherwise is enablement
Insanity is trying the same thing over and over again and expecting different results. You people pushing calorie restriction diets and exercise have a forty year history of short term success followed by long term failure.
The human body is a dynamic system that changes in response to stimulus. Calorie restriction diets cause our metabolism to slow down, requiring even more calorie restriction and exercise to make up the difference. Eventually you are starving all the time and spending enormous amounts of time exercising — just to maintain.
Eventually people get sick of spending four hours a day in the gym and starving themselves. They stop exercising, start eating more and they are worse off than they were before because they have destroyed their metabolism. Everyone who has ever followed a traditional diet for very long is all too familiar with this pattern.
If you are obsessed with calorie restriction, the only way to do it without sabotaging your metabolism is some form of fasting. And fasting is far easier and more effective than calorie restriction diets anyway. Your body is built to effectively fast, and it actually increases metabolism instead of depressing it.
