A review study has been published recently: “The Long-Term Effect of Energy Restricted Diets for Treating Obesity“.
A few quotes from the study:
Energy restricted diets resulted in an average 2.9% […] greater weight loss compared to untreated control groups.
Weight regain was observed in the majority of individuals in all studies.
Since so many individuals are initially successful in losing weight through an energy intake reducing diet, future research should aim to identify ways to prevent weight regain
When prescribing a diet for the treatment of obesity, health practitioners should discuss with their patients that this intervention is only useful if permanent dietary changes are made. The high chance of weight regain and the mechanisms behind the phenomenon should be explained and a plan should be made to prevent weight regain as much as possible. This plan should include a feasible weight maintenance diet, emphasizing that energy intake will have to be permanently lower compared to the situation prior to weight loss.
Disapproval of those who do not succeed to lose weight, or regain weight, is inappropriate. If weight loss is not achieved, the advice to go on a diet should not be repeated automatically, unless a renewed willingness to change is noted.
A 100 Kg person can expect to lose 3Kg as a result of 3-4 years of dieting. That is just amazing…
The authors, instead of saying “energy restriction is BS, let’s forget it once and for all“, they talk about “permanent dietary changes” and “willingness to change“. They admit they have no clue why weight regain happens, but they ask health practitioners to inform their patients about the causes of weight regain and give them a “feasible weight maintenance diet“. What kind of diet would that be, if they don’t know why weight regain happens? But it must be “feasible“, because, you know, we have a problem of willpower here…
Is this what they are saying?
energy restricted diets fail for the majority of individuals in all studies, therefore we conclude that a) caloric restriction works for weight loss and b) you, the obese people, lack willpower to stick to the diet, are too stupid to understand caloric restriction or are willingly sabotaging the energy balance theories.
Future research should aim to identify ways to prevent weight regain, but nevertheless we encourage health practitioners to tell you why weight regain happens and give you a plan to follow in order to avoid weight regain. We know the plan is only useful if permanent changes are made, although we have no idea what those changes are. That’s because no intervention has ever proved to work. But permanent changes are needed and the diet must be feasible, we know that for sure, because we know the problem is that you, the obese people, lack the willpower needed to stick to the diet. And please, stop eating so much.
We will not blame you if you fail. Weight loss needs a strong willingness to change, but we all know that you, the obese people, are weak, lazy and have no willpower. If we advised you to diet again without noting first a desire to change, it would be our fault, not yours.
A desire to change is the key, although we don’t know what kind of change is needed.
LET’S STOP THIS NONSENSE, PLEASE
- Caloric restriction is a weight loss method based on several thinking errors. It’s not derived from physics’ laws, it derives from human stupidity (see,see). There is no good reason for it to work, and as a matter of fact it doesn’t.
- Caloric restriction has been tested in hundreds of scientific experiments and it always fails. The method doesn’t work. That is an indisputable fact.
- The more likely explanation for caloric restriction’s lack of results is the physiological reaction of our body to caloric restriction. That explanation is based on sound science, from human and animal studies. The idiotic “lack of willpower” hypothesis has no scientific backup.
- Caloric restriction has been shown to fail also when there is proof of adherence to the diet.
- When a diet based on sugar, grains, seed oils and processed food is adopted, obesity develops. When people go back to a diet based on real food, they lose weight and their health improves.
- If obesity were caused by laziness and gluttony, that would mean the world population has suddenly become lazy and gluttonous. The idea that this has suddenly, with no clear cause, happened to all kinds of people in all kinds of countries is blatantly stupid and blames the victim for its condition.
