Low-Carb or Low-Fat? Harvard Researchers Found a Clear Winner

Kelsey Clark

The internet has ushered in a new era of misinformation, mostly due to the fact that there's so much of it. This problem is especially prominent in the health and nutrition fields, where nearly every ailment has been analysed and diagnosed from a different medical perspective. Fortunately, we can look to institutions like the Harvard School of Public Health to narrow the playing field and set the record straight.

Most recently, a team of researchers from Harvard and the Brigham and Women's Hospital sought to find the unequivocal winner between low-fat and low-carb diets. The results, published in AAAS, found a weight-loss advantage for low-carb diets, with participants losing an average of 2.5 more pounds than those on low-fat diets. "Despite the pervasive dogma that one needs to cut fat from their diet in order to lose weight, the existing scientific evidence does not support [it]," said Deirdre Tobias from BWH. The researchers came to this conclusion after analysing 53 randomised trials of roughly 68,000 patients who had been assigned to either low-fat or low-carb diets. The average weight loss after one year was six pounds.

That being said, the researchers did emphasise the importance of finding a diet that works for your body. "We need to look beyond the ratios of calories from fat, carbs, and protein to a discussion of healthy eating patterns, whole foods, and portion sizes," concluded Tobias.
