Some time ago, an Australian study  I mentioned here had established that drastic and fast diets worked better than slower weight loss : in reality, if you look closely at the study, a crash diet never meant a diet of three. days or one or two weeks, but of a time ranging from three to six months, while a slower diet obviously means a diet of at least nine months. However, many misunderstood the study, thinking that a crash diet meant a disposable diet. Not so: there are no reliable studies on the effectiveness of diets ranging from a few days to two weeks , this is because when we talk about weight loss we meanloss of body fat , not the initial loss of lean mass and fluids typical of disposable diets of a few days.
Now, for example, this other American study makes fleas on the most popular crash diets in the United States, but always a few months’ diets: South Beach, Weight Watchers, Atkins and the Zon a diet have passed under the slow of researchers to try to understand according to two parameters ( kilos of weight actually lost / weight maintenance after the diet ) which of these was the best. In part, this new study disproves the findings of the previous one: According to the McGill University researchers who conducted the survey, none of these diets are the best.. Not only that: the researchers realized that analyzing the previous studies, out of hundreds of studies only twelve had been conducted with the right scientific criteria and were reliable , everything else was irrelevant, good stuff only to fill the pages of newspapers.
What are the conclusions, if no crash diet is found to be good for weight loss? Far from wanting to discourage those who want to go on a diet, the researchers stated that those who want to lose weight must choose the diet that is closest to their tastes and that seems feasible, but in general they advise against drastic diets, because they are irrelevant in true weight loss, and they claim that the real results are obtained by changing their diet in slow times, for example by eating less (i.e. reducing portions), reducing sugars and fats (less sweets, fewer heavy foods) and doing more activities of any kind.
