Cut Carbs, Not Fat, if You Want to Lose Weight: Harvard study

Cut Carbs, Not Fat, if You Want to Lose Weight: Harvard study

A major study from Harvard University has revealed cutting carbohydrates is far more effective than a low-fat diet if losing weight is the person’s endgame.

They analyzed 53 past studies – involving 67,000 dieters – and found people cutting back on fat weighed more than subjects embracing the low-carb method.

The merits of a low-fat diet have always been a topic for discussion every since it was heralded as the go-to weigh way to shed pounds in the 70s. Now, the low-carb diet seems to have surpassed it.

The study by Brigham and Women’s Hospital and the Harvard T.H. Chan School of Public Health looked at all previous studies from clinical trials that compared the effect of low-fat diets versus other approaches, at least one year later.

Compared with low-fat diets, participants in low-carbohydrate weight loss interventions were about two and a half pounds lighter.

“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 low-fat diets over other dietary interventions for long-term weight loss,” explained Dr. Deirdre Tobias from Bingham’s Division of Preventive Medicine.

“In fact, we did not find evidence that is particularly supportive of any specific proportion of calories from fat for meaningful long-term weight loss.”

While the low-card approach is the most promising according to the study, doctors say any diet with smaller portion sizes and focuses on a healthy, balanced range of fresh and unprocessed foods can be as effective.

“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,” said Dr. Tobias.

“Finding new ways to improve diet adherence for the long-term and preventing weight gain in the first place are important strategies for maintaining a healthy weight.”
