VIDEO: Calorie-Restricted Diets Are Beneficial Regardless of Fat, Protein or Carbohydrate Content (Interview with Dr. Catherine Loria, PhD, National Heart, Lung and Blood Institute)

(February 25, 2009 - Insidermedicine) A calorie-restricted diet can help with long-term weight loss and cholesterol and blood insulin levels no matter what the relative content of fat, protein, or carbohydrates, according to research published in the New England Journal of Medicine.

Here are some ways to help you lose weight:

•    Increase your level of physical activity.

•    Set specific, healthy weight loss goals.

•    Plan your meals ahead of time.

Researchers from Harvard University randomly assigned over 800 overweight adults to one of four calorie-restricted diets. The first had a low fat and an average protein content. The second had a low fat and high protein content. The third had a high fat and average protein content, while the fourth was high in both fat and protein.

After 6 months, the participants lost an average of 6 kg, or about 7% of their body weight. After a year they began to regain weight, but the type of diet they were on did not have much effect on how much weight was gained back. Overall, 80% of participants completed the study, losing an average of 4 kg and improving blood cholesterol and insulin levels.

We had a chance to speak with Dr. Catherine Loria, one of the authors of this study, who offered some further insight.

Today’s research demonstrates how it is possible to lose weight with a range of different types of healthy, calorie-restricted diets.
