Let's talk aboutGenetics and Weight

Do genetic factors influence your weight?

Yes! The fit of your jeans is affected at least in part by your genes. Lots of research has shown that genetics not only impacts how much we weigh but also how much diet and exercise may make a difference. Our weight is the product of genetics, lifestyle, and environment all working together.

Healthy habits make a difference.

It’s no secret that eating well and exercising can help control weight. Most people already know that choosing to eat less of certain foods (e.g. fast food, sweets, red meat) and more of others (e.g. veggies and fruit) can make a difference; along with exercising more, sleeping a healthy amount, and managing stress. But did you know that your genes may affect your body’s response to these healthy choices? Some healthy habits may make a bigger difference for your weight than others, based on your own personal genetics.
