Weight Loss Diet: Low-Fat Diet Caused More Weight Loss Than Low-Carb Diet, Says New NIH Study

If you talk to plenty of people, chances are a good percentage of them are looking for ways to lose weight healthily and effectively. There are nearly three million photos of the “if it fits your macros” diet on Instagram, as reported by the Inquisitr. If that many people are willing to figure out the complex #IIFYM diet in order to experience weight loss, a new study that claims eating less fat is better than eating fewer carbs to lose weight will surely interest them.

As reported by WebMD, the study discovered that a group of people on a low-fat diet who were overweight ended up losing more fat on low-fat diets than on low-carb diets. Admittedly, the NIH study group was small, made of up 19 people. However, those 10 men and nine women were reportedly closely followed when on the low-fat diets. So much so that the group lived at the NIH while the study was conducted — and they were told to eat everything they were given in order for the scientists to get extremely accurate results.

Instead of the breakdown recommended by the “if it fits your macros” diet, this low-fat diet was made up to 50 percent carbs. The remaining 50 percent broke down into 35 percent fat and only 15 percent protein, which sounds awfully slim based on this high-protein focused diet world.

The low-fat diet plans were broken up into two periods, each lasting 11 days. The participants even resided in special rooms that allowed their exhalations, inhalations, and bodily fluids to be studied to determine exactly how many calories they burned and the sources of those calories.

Initially, all of the participants ate enough calories to have their weight levels remain the same. Then they switched to a diet plan that provided 30 percent less calories. One eating plan consisted of the low-carb diet while the other represented the low-fat diet.

The protein and fat remained the same for the low-carb folks, and the low-fat diet folks had their protein and carb levels stay the same. What’s surprising to those who view carbs as the devil was that the low-fat diet provided a greater weight loss than the low-carb diet. Also surprising was that reducing carbs seemed to slow down the participants’ metabolic rates, while reducing fat didn’t do so.

Overall, even though the low-fat diet resulted in more overall weight loss than the low-carb diet, the diets affected the bodies differently — and those differences ended up being pretty complex.
