If you want to lose weight, it’s important to find the right diet. But with so many diets out there, it’s difficult to know which one is best, especially when popular diets are total opposites. How can you choose between a low-fat diet and a low carb diet? Well, thanks to recent research, you don’t have to.

Some research has suggested that a person’s genetic makeup might predict how responsive an individual would be to certain diets.

But last week, the Journal of the American Medical Association published a study that finds that that isn’t the case. The research shows that a person’s genetic makeup actually doesn’t impact weight loss efforts when it comes to low-fat and low-carb diets.

Researchers gathered over 600 overweight or obese adults who ranged from 18 to 50 years old. Researchers then took a DNA test for each individual to identify whether they might be more sensitive to fats, to carbohydrates or for neither nutrient group.

Then, each individual was randomly assigned to either a low-fat or low-carb diet for one year.

Participants didn’t have to count calories. In fact, study author, Christopher Gardner explained that he and the research team “told them how to cut back on carbs and fat. And we encouraged them – pushed them really – to not be hungry, to find their sweet spot.”

After a year, the 305 individuals who tried the low-fat diet lost about 11.5 pounds. The 304 individuals who tried the low-carb diet lost about 13 pounds.

And researchers saw that the initial genetic testing didn’t help to identify which diet would be more suitable for each person.

Instead, study participants lost weight irrespective of their genetic makeup by following their diet consistently over one year.
