Do your genes play a role in how much you weigh? Absolutely! But before you get all excited about blaming genetics for being overweight, lifestyle factors such as diet, meal timing, and exercise are also really important.
This weight loss genotype report shows you how your genes may impact your weight – and specific options to tackle the pathways. We are all different, and a one-size-fits-all approach to weight loss does not work for everyone.
Let’s be honest here: Weight loss takes some hard work, and there are no magic pills based on genetics. Instead, understanding the science may help you to figure out your best path towards a healthy weight for you.
Genetics and Weight:
- Single gene mutations: There are a handful of rare genetic mutations that cause extreme obesity, beginning in early childhood. (Not included here.)
- Multiple genetic variants: For most people, the genetic component of weight is due to the combination of more common genetic variants that add together to promote weight gain, especially in an environment abundant with tasty foods.[ref]
Genetics can show us why we gain weight easily.
Many of the genetic variants related to obesity are linked to the appetite control center in the brain. Leptin (satiety signal) and ghrelin (hunger hormone) are two key hormones regulating appetite, and genes that influence their levels are linked to weight gain.
Several of the obesity-related genetic variants are important in circadian rhythm, the 24-hour built-in clock system in the body. Meal timing is important for weight management – for some people.
A couple of the genetic variants are related to the way that the body expends energy. Some people burn more calories, and some people react differently to using fat for fuel.
