People may tend to overeat from time to time. 

However, binge eating is a different matter. If you always eat a large amount of food in a brief period of time, even when you are not hungry, you’re probably binge-eating.

When you’re binge-eating. you’re also more likely to feel embarrassed or guilty about it.

Your genetics play a significant role in your diet and health, particularly your eating habits. LifeDNA has found 5 important genes that can influence your likelihood of binge-eating.

  • Eating to the point of pain.
  • Eating a whole cake in one sitting and then feeling guilty. 

Your FTO Gene & Your Natural Eating Habits

A variety of genes influence your likelihood of binge eating. These genes have the potential to influence brain circuits that regulate hunger and mood.

One of the genes that our geneticists have looked into is your FTO gene

Your FTO gene is also linked to other traits such as:

  • Saturated Fat Metabolism 

How quickly do you metabolize saturated fats?

  • Satiety  

Trouble feeling full? Ask your DNA.

  • Appetite 

Appetite determines how much you naturally want to eat.

  • Preference for fatty foods 

The food you love to eat is heavily determined by your genetics. 

  • And weight change

Certain genetic variants may increase your likelihood of binge eating, but other factors including your lifestyle and environment can also trigger it.

Here are some other external factors that can affect your binge eating tendencies:

If you often see your parents overeat, you’re more likely to pick up these behaviours.   The practices you acquire from the people around you may have an impact on your eating habits. 

Anxiety and Stress.
