A recent article in the New England Journal of Medicine compared and contrasted four different diets. The conclusion of the article, which studied the results of various dietary combinations in 811 participants was that diets with reduced calories were the most successful regardless of the percentage of fat, protein and carbohydrates. "Among the 80% of participants who completed the trial, the average weight loss was 4kg; 14 to 15% of the participants had a reduction of at least 10% of their initial body weight. The diets improved lipid-related risk factors and fasting insulin levels. At 2 years, 31 to 37% of the participants had lost at least 5% of their initial body weight, 14-15% of the participants in each diet group had lost at least 10% of their initial weight and 2-4% had lost 20kg or more." The average calorie allowance for the subjects was between 1900-2500 calories per day throughout the two year study.
The results of this study indicate that we should all pay closer attention to our portion sizes and have an accurate count of the number of calories we take in each day to achieve meaningful weight loss.
