The Role of Genetics in Weight and Why One-Size-Fits-All Diets Don’t Work: Part 3

Are You Eating the Right Diet for Your Genes?

Since we have established that genetics do in fact play a role in weight gain/ weight loss (see Part 1 and Part 2 of this series), let’s take a look at how this relates to the foods you eat.

Some genetic mutations confer dietary advantages over others. For example, some gene combinations work better with a low carb diet, some with the Mediterranean diet, and others with a low fat diet (this is a small part of the population).

How do genes affect metabolism?

While there is still more to learn on the topic of genetics and metabolism, what we do know is that some people store more energy as fat in an environment of excess, while others lose less fat in an environment of scarcity. In other words, genetics cause some people to burn fat at a higher rate (high metabolism) while others burn fat at a lower rate (low metabolism). These differences are largely due to genetic variations.

How do you know which diet is right for you?

The simple answer: genetic testing. But don’t settle for labs that only test five or six genes. Our bodies have a multitude of gene combinations that we are only just uncovering and testing five or six out of trillions of potential combinations will not be sufficient.

We use Pathway Genomics for genetic testing. To date, Pathway Genomics tests the largest number of genes to determine the proper gene-diet combination.

What foods should I eat?

With or without genetic testing, we know one thing: real foods are packed with nutrients and compounds that can help you lose weight and prevent or overcome a myriad of health problems and diseases. No mater your genetic makeup, here are a few tips everyone should follow:

  • Eat real foods. Stick to whole, unrefined, and unprocessed foods to get the right nutrients—protein, fat, carbs, vitamins, and minerals—you need to stay lean and healthy.

  • Eat a variety of colors. When shopping for produce, choose a rainbow of colors. Different colored fruits and vegetables contain different essential nutrients, so be sure to mix things up and eat a variety.

  • Eat fresh, organic foods whenever possible. Locally grown, fresh, organic foods are the best option, and far better for you than frozen or canned foods.
