I definitely relate to this feeling as overweight/obesity runs in my family. I grew up with lots of pressure thinking the cards in the deck were stacked against me. And many of my weight loss coaching clients come to me in despair wanting to lose weight, but believe they are fighting a losing battle because they have fat genes (and fat jeans). But when you study the research, there’s lots of good news when it comes to genetics and your weight and health.
The International Journal of Obesity did a study using twins. One twin was labeled the "gym rat" and worked out regularly, and the other twin was the "lazy twin". After 30 years, the scientists compared the gym rat and lazy twins and found that the gym rat had gained nearly 12 pounds less, and had a waist that was over 3 inches smaller, than the lazy twin.
