Nutritional trend 2022: lose weight with nutrigenetics?

What does nutrigenetics mean?

To a certain extent, genes are the instructions for the construction and use of our organism. Our genes determine how certain processes are carried out in our bodies, how tall we grow, the color of our eyes, and our susceptibility to the development of certain diseases. Our genes make us the people we are. However, 99.7 percent of all people’s genes are completely identical. We differ from each other in only 0.3 percent of our genes. But that 0.3 percent obviously has a huge impact on how we look and how our bodies work. Some people cannot tolerate gluten or cannot digest lactose. Other people have extremely fast metabolisms and can eat without accumulating many fat stores. The reason for such individual peculiarities lies in the smallest variations in our genes.

This is where nutrigenetics comes in. Nutrigenetics is a branch of nutrition research. Nutrigenetic researchers investigate Connections between diet and human genetics. And exciting discoveries have been made in recent years. The researchers identified the FTO gene, for example, which appears to be linked to the development of obesity. The gene determines the extent to which fat cells burn or store fat. The well-known lactose intolerance is also due to a specific gene. In people who are lactose intolerant, the gene responsible for controlling the lactose-degrading enzyme lactase is inactive.

Based on such scientific findings, a kind of nutritional trend has developed around nutrigenetics. There are now a number of lifestyle companies offering genetic testing evaluations to provide customers with personalized nutritional recommendations based on their own genes.

How does the Personalized Genetic Diet work?

The idea sounds tempting: a tailored nutrition plan based on DNA analysis. Lose weight and live healthy with the help of information from your own genome. Providers of such genetic diets and nutrigenetic analyzes sell test kits to interested parties with which they can take a saliva sample. The saliva sample is then sent to the genetic testing provider, who has the sample analyzed in a laboratory. In most cases, the genes are actually sequenced. After a few days or weeks, customers receive the result of the genetic analysis and find out, for example, what their genes supposedly reveal about their metabolic types, which sports activities promise success, or what amount of calories is optimal. Only: Science is still a long way from naming the actual causal relationships between certain genes and food utilization.. Although links between genes and certain diet-related diseases are known, this is not yet sufficient for the creation of personalized nutrition plans.

Nutrigenetics: Don’t Blindly Trust Lifestyle Products

The nutrigenetics approach is quite understandable. Our genes dictate the plans of our body and how all the metabolic processes carried out by our organism work. How we react to food, whether we are prone to allergies or developing certain diseases, depends on individual variations in our genes. Therefore, it is natural to investigate the extent to which our genes influence how nutrients are processed and converted in our body.

And as great as many people are for personalized nutritional advice based on gene analysis, there is still no scientific basis for making reliable claims about the interaction between genes and nutrition. Many freely available test kits for single gene analysis are pure lifestyle products. It is not yet possible to draw specific genetic conclusions about personalized nutritional recommendations. If you want to lose weight or live a healthier life with nutrigenetics, never blindly trust the results of genetic tests. Use the results as a guide to learn more about a specific food or diet, but don’t get bogged down in unscientific genetic analysis. The best way to lose weight and lead a healthier life is through a balanced diet of fresh fruits and vegetables and getting enough physical activity.
