Is it Possible to Pick a Diet Based on Your DNA?

Different diets may work for different people because of their genetic predispositions. This could be one reason why many people who struggle with obesity, despite traditional dieting efforts, aren’t able to budge the scales too much. However, if aspiring dieters invest in a DNA test, they may find that their genetics can help them choose a diet that will lead them to satisfying results. 

Diet Plans & Genetics

Everyone Has a Different Metabolism

As long as dietary guidelines have existed, they have taken a one-size-fits-all approach. Both the food pyramid and the recommended daily calorie intake are to blame for some of the Americans living with metabolic syndrome (cardiometabolic risk factors). We have grown up with the idea that the biggest portion of your diet should be grains, usually wheat, and the rest should be balanced portions of meat, dairy, vegetables, fruit, and sugar.

However, many people metabolize energy differently and so it gets stored differently. If you have a genetic predisposition that causes you to store too much fat instead of breaking it down for energy, you will generally gain weight and be fatigued by the lack of energy. Therefore, isn’t necessarily your fault that even after balanced meals and exercise you retain the weight.

DNA Diets Eliminate the “Bad Foods”

As an experiment, researchers designed four genetically different strains of mice, to which they fed four different but most popular human diets: American/Western, Mediterranean, Japanese, and Maasai/ketogenic. The American diet was high in fats and refined carbs, the Mediterranean was higher in fiber and included red wine extract, the Japanese diet consisted of rice and green tea extract, and the ketogenic diet was high in fat and protein but consisted of very few carbs.

The mice were also fed a control diet consisting of standard food. The researchers monitored the mice’s cardiometabolic health, measuring their blood pressure, blood sugar, cholesterol levels, and looking out for signs of a fatty liver. Levels of physical activity were also monitored, as well as the rodents’ appetite and food intake.

The mice all responded differently. Three performed well on the three “healthier” diets, the fourth genetic strain responded badly to the Japenese diet. On the ketogenic diet, two became fat — one obese and the other “skinny-fat.” As suspected, the Western diet negatively impacted all four mice. The Mediterranean had healthier but mixed results.

Find The Diet Plan for You

As with the mice, humans will all have various differences in their diets, even within the same families. Test Smartly can help you determine your DNA ancestry so that you can use what you learn from our DNA tests to help you find the right diet plan for you.
