Cutting instead of calories keeps balance away;

In a study of overweight people are entitled to weight loss, those on a low carbohydrate diet burned about 250 more calories per day than even on a high carbohydrate diet.

The study of 164 people, recently released by the BJ Medical Journal, noted the challenge of prevention of weight loss in the face of the resulting hunger and metabolism, and says that the calorie-burning effect of a low-carb diet can Improve the success of obesity treatment. "

"The findings show that all calories are unlike the body, and that reducting carbohydrates can be a better strategy for long-term weight loss than reducing calories," said Co-author David David Ludwig, Co-Director of the New Weight Base Obesity Prevention Center at Boston Children's Hospital.

The study adds one of the most waxing problems in weight loss: as the weight comes off, the body fights back, burns less calories and bombards us with hunger signals.

"It's a recipe for failure," said Ludwig.

There is also something of a mystery: why does the body reaction like it's starving when it is clear? For some researchers, including Louisville, the answer lies in the carbohydrate insulin model, the process of carbohydrates, such as white bread trigger hormonal changes that lead to hunger, metabolic slowdown and weight gain.

Processed carbohydrates digested quickly in sugar, raising insulin levels, Ludwig said. Insulin, in turn, processes fat cells to store excess calories. When calories are stored in fat cells, the brain can not see them and think that the body needs more food.

The authors of the study collaborated with framingham state university, where 164 overweight people – students, staff, faculty and community members – agreed to eat only taught-supplied food. First, study participants lost about 12 percent of their body weight, approximately 20-25 pounds for the average participant.

"We know that going to print their metabolism," said Ludwig.

Therefore, for the 20-week test phase, study participants are randomly placed in three groups: those who did diets composed of 20 percent carbohydrates, 40 percent or 60 percent. Each diet contains 20 percent protein, with the remaining portion of fat. Diets used healthy foods and as much as possible, Ludwig said. The goal at this stage was to maintain the weight loss, not to lose any more weight.

Those in the low-carb diet burned 209 to 278 more calories per day than those on the high-carb diet, a difference that would lead to an estimated 22-point weight loss over three years if researchers were not intermitting to maintain weight.

The effect was even greater for those who produce high insulin levels in response to carbohydrates; They burned 308 to 478 calories a day on the low-carb diet as they did on the high-carb diet.

How Do You Know If You Are a High Insanely Secret? "Look at the mirror," said Louisville lawyer. "If your fat distribution is predominantly around the midsection – so you are more like an apple than a pear – you are more likely to be a high insulin secretion."

Physics activity levels are very similar to the three diet groups before the study started, Ludwig said.

The researchers encouraged all participants to maintain their habitual physical activity, which is monitored. During this study, the low-carb group has a tendency toward more moderate and vigorous physical activity, perhaps as a result of diet, Ludwig said by email. But he emphasized that the exercise was only a minimum component of the burning effect on calories burned.

A co-author of a 2015 Pls One Journal Article comparing low-fat and low-car diets praised the precision and design of the new study, including the direct bill of energy expenditure, which is difficult and intensive.

"I think they have brought a sophistication that you do not tend to see the trials," said Dr. Jonathan Suttner-Bernstein, a former Food and Drug Administrative Associate Center Director for Technology and Innovation who is consulting for drug and resource companies .

Soccer-Bernstein has the study reinforced his belief that the more sensitive you are to carbohydrates, in terms of your insulin response, the more important it is to be on a carbohydrate-restricted diet.

Ludwig has the results of the study very close to what the authors have predicted, but more work needs to be done.

"This is one study, so the findings need to be replicated and examined in a broader population – although we have quite a demographic variety in our participants," he said. "We need to see how this can affect other studies, as other populations would respond."
