Most weight loss programs focus on a low-carbohydrate diet. In terms of successful and sustainable weight loss however, this diet isn’t suitable for every person as many studies demonstrate. One reason for this problem is the individual genetic make-up, since everyone metabolizes macronutrients differently. An individual diet plan for sustainable weight loss that is based on the genetic make-up and thus each person’s metabolic subtype (Meta-type) is provided by the nutrigenetic analysis MetaCheck. The aim of this study was to investigate, if there is only one type of diet that is suitable for everyone, while considering the individual genetic predisposition. A statistical study with 16,641 randomly selected MetaCheck analysis results was carried out to analyze how the different Meta-types are distributed and whether there is any association between Meta-types and demographic data. The results demonstrate that different Meta-types are distributed quite evenly in the European population. Further the Meta-types are not associated with age, gender or BMI and demonstrate no person’s risk for becoming overweight. In conclusion, general recommendations for everyone to lose weight isn’t a promising solution. Instead, there is a strong need for an individualized weight loss therapy, which is based on the individual Meta-type.
