It has been a fundamental tenet of nutrition: When it comes to weight loss, all calories are created equal. Regardless of what you eat, the key is to track your calories and burn more than you consume. But a large new study published on Wednesday in the journal BMJ challenges the conventional wisdom. It found that overweight adults who cut carbohydrates from their diets and replaced them with fat sharply increased their metabolisms. After five months on the diet, their bodies burned roughly 250 calories more per day than people who ate a high carb, low ­fat diet, suggesting that restricting carb intake could help people maintain their weight loss more easily.

What it shows The new research is unlikely to end the decades­long debate over the best diet for weight loss. But it provides strong new evidence that all calories are not metabolically alike to the body. And it suggests that the popular advice on weight loss promoted by health authorities — count calories, reduce portion sizes and lower your fat intake — might be outdated. “This study confirms that, remarkably, diets higher in starch and sugar change the body’s burn rate after weight loss, lowering metabolism,” says Dr. Dariush Mozaffarian, the dean of the Friedman School of Nutrition Science and Policy at Tufts University, who was not involved in the research. “The observed metabolic difference was large, more than enough to explain the yo­yo effect so often experienced by people trying to lose weight.” Dr. Mozaffarian called the findings “profound” and said they contradicted the conventional wisdom on calorie counting. “It’s time to shift guidelines, government policy and industry priorities away from calories and low fat and toward better diet quality.” The new study is among the largest and most expensive feeding trials ever conducted on the subject. The researchers recruited 164 adults and fed them all of their daily meals and snacks for 20 weeks, while closely tracking their body weight and a number of biological measures.
