A small carb diet could be the best to keep weight loss, says the study



A study published on Wednesday in the BMJ magazine involved 164 overweight or obese people. Their weight was reduced by 12% and they were stabilized with this weight and a high, medium or low carbohydrate diet was administered within 20 weeks.

The diet consisted of 20% carbohydrates and proteins and 60% fat, 40% carbohydrates and fats and 20% protein or 60% carbohydrates and 20% protein and fat.

"We found that dieters who ate had a significant impact on their metabolism. Those in low-carbohydrate diet eaten about 250 calories a day more than a high-carbohydrate diet, although all the groups had the same weight," said Dr. David Ludwig, Research Fellow and Boston Children's Hospital Death Risk Prevention Center, New Balance Foundation.

While participants participated in these diets, their intake of calories was monitored to maintain their original weight. When a participant started losing or increasing weight, their calories increased or decreased.

"If any substance gets worse, they could begin to lose weight, and this made us increase calories just to restore weight to that end," said Ludwig, who is also a pediatrician and nutrition professor at Harvard University.

He said that the study looked at the effects of diet directly on metabolism, which is one of the things that work against you when you try to keep weight.

"These findings suggest that all calories in the chemical are not similar, and carbohydrate containment may be a better strategy than limiting calories to long-term success," said Ludwig.

He also believes that there is no intervention in calorie control with a low carb diet in a few years could spontaneous weight loss of around 20 pounds.

"This seems to be an important fact, but I would be very cautious because the interpretation of the results seems rather wrong," said Naveed Sattar, a metabolic professor at the University of Glasgow in a written statement.

Sattar, who was not involved in the study, said that a low-carbohydrate group seems to eat more calories than other groups that have had a similar weight.

"It indicates the second is that what really matters is weight change, and we already know from much larger and longer studies that weight loss is largely similar, regardless of what diet consumes (low carbohydrate or low fat or others) as long as the diet stays healthy, "he said.

"So, in short, I do not think this work will change anything, and it also does not allow me to convince me that low-carb diets are significantly better for the relevant health outcomes." Big evidence does not justify that. "

Experts also indicated that all participants had the same metabolic rate, so other non-specific activities could explain the differences and increase the saturated fat content of low-carbohydrate diets, which could lead to an increased risk of cholesterol and heart disease.

Kevin McConway, professor of emeritus at the University of Applied Statistics, noted that "since different diets should have been made up of foods that could differ in nature, not just because of their carbohydrate and fat content, it is still possible that these other differences are responsible for part of the observed energy cost differences.
