Evidence points to the fact that dramatic weight loss that stays off is possible, however over twenty years of research points to the fact that’s its highly unlikely that lost weight will not return. The scientific evidence was presented in Channel 4’s Super slimmers, did they really keep the weight off.
1. Significant weight loss is usually followed by regaining most, all or even more weight than was initially lost.
Dr Thomas Barber Human Metabolism Research
Unit University Hospital Coventry:
"This is a hard wired response deeply set within our genetic architecture to change that it's not easy.
"The majority of people who lose weight ultimately do regain that weight. Certain studies have shown that over the course of 3 to 5 years the majority of people who have lost weight will then regain most of that”.
Professor Traci Mann, Health and Eating Lab
University of Minnesota:
“Very few people know that diets don't work in the long run. Their body is changing, physically changing because of dieting”.
2. The body will try to replenish lost fat
“The current theory is that it comes down to our genetic hard wiring. During evolution one of the biggest threats to our species survival is starvation. Any loss of fat mass would have typically occurred during famine and so it makes sense, during those circumstances, to conserve energy and lay down more fat to mitigate the harmful effects of starvation. When we go on a diet and we lose weight that is a similar biological scenario to being starving.
“The bottom line is that regardless of how much weight you lose and the rapidity of that weight loss, the body will respond typically to regain the way that you've lost”.
