Can Your Genes Make You Fat?

Have you ever wondered why some people seem to do very well on a diet and exercise plan, while others seem to fail when using the same plan? Much of this is due to the fact that everyone has a unique body type and body shape that will respond differently to a specific workout or nutrition plan. This is all spelled out in my book Get-Fit Guy’s Guide to Achieving Your Ideal Body.

But this week, a study hit the news that the way your genes express themselves (also known as epigenetics) can predict whether a specific diet or exercise regimen will work for your body. This is exciting because it means that at some point in the near future, a simple salivary test may be able to tell you what kind of fat loss or muscle gain program is going to work best for you.



So if all of this genetic fitness and diet customization is a reality, what about the opposite end of the spectrum? Can your genes make you fat? Is there such a thing as a fat gene or a genetic propensity for obesity? In this episode, you’re going to learn the truth about fat and genetics, and find out what you can do about it.

Is There a Fat Gene?

Studies for the past decade have demonstrably proven a link between genetics and propensity for overweight or obesity. For example, this report looked at a UCLA study in which researchers gave more than 100 genetic variations of mice a normal diet for 8 weeks, followed by a high-fat, high-sugar diet (aka, a “Standard American Diet”) for another 8 weeks.
