Dieting according to your blood type has no beneficial effect on weight gain, according to a new scientific study. In fact, all blood groups have an interest in eating a plant-based diet to lose weight.

We can no longer count the number of diets touting guaranteed, rapid and lasting weight loss. One of them, the blood group diet, consists of changing the content of one's plate according to one's blood type in order to lose weight: people in group A are invited to eat more foods of plant origin, while 'a diet rich in meat is recommended for people in group O.

Published on December 4 in the Journal of the Academy of Nutrition and Dietetics, a new study demystifies this diet and shows that the blood type has nothing to do with the benefits observed when we eat more foods of plant origin .

 This study was conducted using data from other work published in the JAMA Network Open on November 30. 3,115 overweight people with no history of diabetes were randomly assigned to two groups, one consisting of a low-fat, vegan diet for 16 weeks, while the other, the control group, did underwent no change in diet. Of course, experience showed that the vegan diet boosted the metabolism of participants, with an increase in post-meal calorie consumption of 18.7% on average for the vegan diet group compared to the control group.

After collecting data about the blood types of participants on the vegan diet, the researchers found that the blood type made no difference in weight loss, blood lipid levels and blood sugar levels. . In other words, people with blood type A did not get more benefit from this diet than those with group O, contrary to what the “blood group diet” suggests.

 “While the [blood group based] diet says that a plant-based diet should be better for blood group A and less good for blood group O, it has been shown to be beneficial for all people regardless. their blood type, and there was no evidence that meat-based diets are good for everyone, ”commented Neal Barnard, lead author of the study and chairman of the Physicians' Committee for Responsible Medicine. (“Physicians Committee for Responsible Medicine”).

“Our research shows that all blood groups benefit from a vegan diet based on the consumption of fruits and vegetables, legumes and whole grains, when looking specifically at weight loss and cardiometabolic health in adults. overweight ”, concluded the researcher.
