    N.E.J.M. Weight Loss with a Low-Carbohydrate, Mediterranean, or Low-Fat Diet


    It's a 13 pager, but well worth the read.

    Here is the abstract from it...

    Background
    Trials comparing the effectiveness and safety of weight-loss diets are frequently
    limited by short follow-up times and high dropout rates.
    Methods
    In this 2-year trial, we randomly assigned 322 moderately obese subjects (mean age,
    52 years; mean body-mass index [the weight in kilograms divided by the square of the
    height in meters], 31; male sex, 86%) to one of three diets: low-fat, restricted-calorie;
    Mediterranean, restricted-calorie; or low-carbohydrate, non–restricted-calorie.
    Results
    The rate of adherence to a study diet was 95.4% at 1 year and 84.6% at 2 years. The
    Mediterranean-diet group consumed the largest amounts of dietary fiber and had the
    highest ratio of monounsaturated to saturated fat (P<0.05 for all comparisons among
    treatment groups). The low-carbohydrate group consumed the smallest amount of carbohydrates
    and the largest amounts of fat, protein, and cholesterol and had the highest
    percentage of participants with detectable urinary ketones (P<0.05 for all comparisons
    among treatment groups). The mean weight loss was 2.9 kg for the low-fat group, 4.4
    kg for the Mediterranean-diet group, and 4.7 kg for the low-carbohydrate group (P<0.001
    for the interaction between diet group and time); among the 272 participants who completed
    the intervention, the mean weight losses were 3.3 kg, 4.6 kg, and 5.5 kg, respectively.
    The relative reduction in the ratio of total cholesterol to high-density lipoprotein
    cholesterol was 20% in the low-carbohydrate group and 12% in the low-fat group
    (P = 0.01). Among the 36 subjects with diabetes, changes in fasting plasma glucose and
    insulin levels were more favorable among those assigned to the Mediterranean diet than
    among those assigned to the low-fat diet (P<0.001 for the interaction among diabetes
    and Mediterranean diet and time with respect to fasting glucose levels).
    Conclusions
    Mediterranean and low-carbohydrate diets may be effective alternatives to low-fat
    diets. The more favorable effects on lipids (with the low-carbohydrate diet) and on
    glycemic control (with the Mediterranean diet) suggest that personal preferences
    and metabolic considerations might inform individualized tailoring of dietary interventions.

    A large study also came out and said that while there are some really nice benefits to low carb and especially mediteranean diets. For weight loss they all performed basically the same and SURPRISE its's the amount of calories that matter most in a weight loss program.

    How much money do you think that costs to figure out??
