A Swedish researcher discovered that following a Paleolithic diet would guarantee a more important and lasting weight loss after menopause, and had health benefits. Explanations.
For a start, what is the Paleolithic diet? Popularized in France in the early 2000s, the so-called "paleo" diet consists of eating as did our ancestors of the Paleolithic (prehistoric period ranging from 2.5 million to 12 0000 years BC).
At that time, human society consisted mainly of hunter-gatherers who knew nothing about farming techniques. Adepts to this diet, which only allows natural and unprocessed products, so eat meat, eggs, fish, fruits and vegetables, convinced that diseases such as cancer, obesity or Diabetes appeared with agriculture.
A 2-year follow-up study
According to a study conducted by Caroline Blomquist, a PhD student in the Department of Public Health and Clinical Medicine at the University of Umeå, Sweden, overweight women after menopause who are on a paleo diet are more likely to maintain a loss. weight in the long run. As well as reducing their levels of risk factors for type 2 diabetes and cardiovascular disease.
To obtain these conclusions, the researcher followed for two years a group of 70 postmenopausal women with a body mass index greater than 27, that is to say, being overweight. Postmenopausal women have a higher risk of obesity, particularly because of reduced estrogen production.
The paleo diet, pledge of weight loss and health
Half of the women therefore followed a diet that conformed to the Nordic recommendations for nutrition, while the other half followed a so-called Paleolithic diet. A first examination took place after six months and another after two years.
The results show that both groups lose weight, but that the women who had followed a Paleolithic diet reached a weight between 87 to 78 kilos, against 86 to 80 kilos for the other group. A significant reduction in unhealthy abdominal fat is also observed in women who have followed a Paleolithic diet.
Their levels of certain fatty acids and certain blood fats also decrease, which in fact reduces the risk factors for type 2 diabetes and cardiovascular disease.
"The study shows that the Paleolithic diet with a high intake of unsaturated fats is healthier for this group of women, although Nordic nutritional recommendations also have positive effects on health," concludes Caroline Blomquist.
