Have you ever tried to lose weight by cutting calories? Did it work for a long time? Could you keep the weight off? My guess is that if you are reading this book, you are not alone. According to data from the UK, 1 in 124 obese women get results using this method, meaning the nutrition guidelines some professionals are following have a 99. A quick look at what happened to the contestants on the hit TV series "The Biggest Loser" should stop you from doing this method. The show is an example of why eating less and moving more is only a short term solution. There are a lot of reunion shows. Why are low calories diet flawed?
The results of a study on 14 contestants on the biggest loser show were frightening. The study showed that the initial results were short lived. Some of the factors were tested.
● Average weight before filming: 328 lb/ 148 kg
● Average weight after 30 weeks on the show: 199 lb/ 90 kg
● Average weight six years after final: 290 lb/131 kg
During filming, contestants lost a lot of weight, but struggled to maintain it over a long period of time. One of the 14 people who took part in the study kept their weight off. That's over a 98% fail rate.
Why is this happening?
The results show contestants Resting metabolic rate.
Resting Metabolic Rate
The amount of calories the body burns to stay alive is referred to as the RmR. In some places it is measured in BMR. The results below are shocking because the majority of your metabolism is done by RmR.
● Average RMR before filming: 2,607 kcal burned / day.
● Average RMR after 30 weeks on the show: 1,996 kcal burned / day.
● Average RMR six years after final weigh-in: 1,903 kcal burned / day.
Even though contestants put around 70% of their initial weight back on, their RmR did not return to its pre- filming levels. It was 700 calories lower a day. contestants would need to eat 700 less calories than they did on the show to lose the same amount of weight. The original diet has 1200 - 1500 calories with 90 minutes of exercise six days a week. This would be impossible. The contestants stayed low even though they put the weight back on.
