Scientists from the University of Aberdeen-Scotland and the Chinese Academy of Sciences undertook a study that is the most comprehensive in the distribution of fats, starch or of proteins.
As foods consist of fat, protein and starches, it is difficult to accurately determine which component of the food is ideal for causing weight gain.
Part of the problem is that it is difficult to conduct human studies and control them by eating them long enough to spread the most important factors, but studies of animals that look like us may help move in the right direction.
This study was published on July 12 in the journal Cell Metabolism and included 30 different diets in the proportions of fat, carbohydrate (sugar) and protein.
The mice fed these diets for three months, which equates to nine years in humans.
A total of more than 100,000 measurements of body weight changes were made and lipids were measured using a miniature MRI machine.
Professor John Spekman, head of this study, said, "The results of these massive studies are unequivocal: the only thing that got the mice fattened was to eat more fats: starchy foods, which accounted for up to 10%. 39% to 30% of calories The sugar came from no effect.
The combination of fats and sugars did not have more effect than fat alone.It There is no evidence that low protein (less than 5 percent) stimulates appetite, suggesting that there is no effect on proteins.
The obvious limitations of this study are that they are based on mice, not on humans, but mice have many similarities with humans in physiology and metabolism. We will never do those studies where diets humans are controlled in the same way for long periods, and their introduction is a good indication of what are the potential effects of different diets on humans.
