According to a new study published in the journal BMJ, diets low in carbohydrates are best for losing weight. If you recently started taking Phentermine 37.5mg and want to make diet changes, take a moment to learn about this study.
The Metabolism Factor
A group of 164 overweight or obese individuals participated in the study and had their weight brought down by 12% before they were put on high-, medium- or low-carbohydrate diets for 20 weeks. The diets featured “20% carbs and protein and 60% fat, 40% carbs and fat and 20% protein, or 60% carbs and 20% protein and fat.”
“We found that the type of diet people ate had a major impact on their metabolism. Those on the low-carbohydrate diet burned about 250 calories a day more than those on the high-carbohydrate diet, even though all the groups were the same weight,” said Dr. David Ludwig, principal investigator of the study and co-director of the New Balance Foundation Obesity Prevention Center at Boston Children’s Hospital.
Caloric intake was controlled so participants maintained their baseline weight.
“If somebody’s metabolism speeded up, they would have started losing weight, and that would have triggered us to increase calories just to restore weight to that baseline target,” said Ludwig.
Not All Calories Are Alike
Researchers studied how diet specifically affects the metabolism since an individual’s metabolic rate can interfere with maintaining weight.
“These findings show that all calories are not alike to the body from a metabolic perspective and that restricting carbohydrates may be a better strategy than restricting calories for long-term success,” Ludwig said.
However, the low-carb group appeared to consume more calories than other groups who maintained similar weights.
“What really matters is weight change and we already know from much larger and longer trials that weight loss is broadly similar whatever diet one takes (low carb or low fat or others) as long as one sticks to the diet,” said Naveed Sattar, professor of metabolic medicine at the University of Glasgow, who was not involved in the study.
