People use a number of methods to lose weight. The most common style of common man for weight loss is reduction of the food intake or diet control. Unknowingly they go on fast or go to a state of starvation. Now you can choose the appropriate diet to control obesity. A very recent research can guide you for the same purpose.
A study conducted by Dr. David Ludwig, director of the New Balance Foundation Obesity Prevention Center at Children’s Hospital Boston says that from a metabolic perspective, all calories are not alike and the quality of the calories going to affects the quantity of the calories going out. The study was published Tuesday in the journal of American Medical Association.
In the study Dr. Ludwig and his colleagues hired 21 over weight adults between the ages 18 to 40. During 2006 to 2010, they marched the volunteers through several controlled feeding studies. The volunteers followed 3 months weight loss program and they loose 10 to 15 percent weight. After this period the program was followed by 4 weeks weight stabilization phase. And after this phase they were given different diets for 4 weeks. a low-fat diet limiting fats to 20% of total calories; a low-carbohydrate diet modeled on the Atkins diet, limiting carbohydrate intake to 10% of total calories; and a low-glycemic-index diet, which contained 40% of total calories from carbohydrates, 40% from fats and 20% from protein.
Different types of diets gave different results. Low fat diet gave the worst result on energy expenditure.
Low carbohydrate diet gave the best result, burning about 300 more calories per day, but with a side effect regarding heart diseases and diabetes related risk.
The low-glycemic-index diet burned about 150 calories a day more than normal. This result was without any harmful effect.
Weight-loss experts not involved in the research praised it, while acknowledging its limitations. “It’s a small study, so I’d want to see it repeated. But I have no reason to doubt the result,” said Susan Roberts, a professor of nutrition and psychiatry at Tufts University in Boston.
Dr. Ludwig said that we should not severely restrict any major nutrient but we should focus on the quality of nutrients. He also didn’t recommend a very low-carbohydrate diet even though it offered the best metabolic edge. Some measurements suggested it could be risky for the heart, he said.
