Everywhere you can find tips for particularly effective diets that promise rapid weight loss without the yo-yo effect. But which diet is really effective? We have checked the studies for you.
Low-fat and low-carb diets are particularly well known. With the two nourishing forms it concerns in each case to do without on a nutrient particularly strongly, either on fats or on coal hydrates. This is supposed to lead to weight loss.
In a 2014 meta-analysis, Bazzano et al. concluded that a low-carb diet is significantly more effective than a low-fat diet in terms of weight loss, fat mass and cholesterol levels. The study was conducted with overweight adults over 12 months. Overall, the low-fat group lost just under two kilograms, while the low-carb group lost a good five kilograms. For some factors, such as blood pressure, there were no significant differences between the groups at the end of the study period. However, another meta-analysis from 2015 cannot find any significant differences in terms of weight changes between low-fat and low-carb diets. And also in a study from 2018 with a good 600 test persons* no significant differences between the two diets can be found after 12 months. The study situation is therefore inconclusive for these two diets, but it suggests that the selected diet form is not decisive.
