Do Genes Play a Role in Weight Loss?

genetics and weight loss

Genetic predispositions affect our health in many ways. For example, your genetics can determine your risk of getting certain types of cancer, experiencing hair loss, and developing all kinds of diseases like diabetes or heart disease. Many people believe that genetics also plays an important role in our ability to lose weight. However, while our body types do depend largely on genetics, the same may not be the case with weight loss.

In this article, we will be exploring the link between genetics and weight loss.

Genetics and Obesity

Studies have long explored the link between obesity and genetics. For example, a 2017 study published in the Nature Research Journal tried to determine exactly which genes are linked to obesity. During their research, the scientists found that 13 genes were linked to changes in our BMI (Body Mass Index). According to this study, these genes play a vital role in our body weight control.

This study provided a valuable insight into why some people lose or gain weight more easily than others.

Genetics and Weight Loss

On the other hand, another study came to a completely different conclusion. A team of Stanford scientists examined the data retrieved from over 600 overweight people over a period of 12 months. The subjects went through insulin and genetic testing before being put on a low-carb or low-fat diet.

The scientists found that people whose diet revolved around healthy foods lost significantly more weight than those whose diets were unhealthy. These results were independent from genetic factors.


So, is there a link between genetics and weight loss? While our genetics certainly affect the way we gain and lose weight, it seems that a healthy diet based on green vegetables can neutralize any effects that genetics may have.
