Children play with confidence: they demand in advance, they promise success, and in the end, they have so many different effects on different people that you can almost hear contempt. While for some, weight remains constant with regular intake of carbohydrates, in others it is precisely what determines the increase in number on the scale. The question remains: If a diet cannot do the same for every person, what determines the success of the customer? This is exactly what is analyzed in nutrigenetics, the science of how nutrients are processed in the body. This not only helps to identify possible intolerances, but also explains why dieting does not change the weight of everyone.
Nutrigenetics: how genes and the environment affect the success of weight loss
Nutrigenetics experts discover how the body responds to different groups of nutrients – including protein, carbohydrates, fats – and how effectively it can metabolize them. Genes are used to define how much fat the body pulls from food and, at worst, attach itself to the hips and co. Because of this, some people will eat without hesitation, while others will increase in the near future. This physical difference is already in the DNA, but it is also supported by proper nutrition and a good amount of exercise. Because it is not just the genes that decide the weight, the environmental influences play a role here. Nutritionist Elizabeth Mayer-Davis of the University of North Carolina told the New York Times: "When you lose weight, you have to think about biological conditions, society and culture at the same time. If you neglect only part of the diet, the diet is likely to work less well. nutrition study. ”In an extremely unhealthy diet, known genes work against weight gain but can do relatively little in the long run.
Are there nutritional tips that can be applied to everyone?
Nutrition and associated weight are individual and can only be perfected by a diet adapted to: finding possible intolerances and eliminating certain foods from the diet, relying on nutrients that can be best metabolized by the body and avoiding unhealthy products as much as possible, to find out its genetic needs and adapt meals to him, a genetic check can be done and a specially adapted diet can be developed.
In the meantime, numerous studies have shown that customer success depends on the individual and that it is only possible to use DNA testing to find out which diet is best for you. Gene analysis, among other things, whether the body is either broken down by fat or carbohydrates less well, thereby providing weight gain. Kevin Hall, a scientist at the National Institutes of Health, conducted a study and compared processed products with raw materials to clarify whether additional nutrient-independent factors contribute to customer success. Result: In the processed foods diet, subjects ate about 500 calories more per day and gained weight during the study. This has allowed scientists to say that even foods that are declared healthy, such as granola bars, frozen foods or packaged foods, pose a problem in nutrition and work against weight loss. Therefore, the logical conclusion of the diet is to focus on fresh foods, lots of vegetables and fiber, which increase weight gain.
