Researchers have found that among the three major food groups، fat is the only cause of weight gain in the long run، as the Technical Times said.
In the most comprehensive study yet of its kind، researchers at the University of Aberdeen in Scotland and the Chinese Academy of Sciences in Beijing، China concluded that only fat causes mice to gain excessive weight over a long period of time.
The findings of the study could potentially put a nail in the coffin on the long-standing controversial debate on which among the several diets in the world is the best for avoiding excessive weight gain. Food is made up of the three macronutrients، such as carbohydrates، protein، and fat. The goal of the study was to see which among these macronutrients caused weight gain in mice. The research published in the journal Cell Metabolism examined a total of 30 different diets، each one having different proportions of carbohydrates، protein، and fat.
The scientists conducted the study on laboratory mice. Each of the mice was made to eat a single diet for three months. This is equivalent to nine years for humans.
Over the course of the study، the researchers made more than 100،000 measurements of changes in both body weight and body fat in the mice using micro MRI machines.
