Time to Take Low-Carb Diets Seriously?
Posted 08/10/2004
Summary
In two randomized trials, researchers compared low-carbohydrate diets with
low-fat diets to assess effects on cholesterol levels and weight loss.
In a 24-week study, 120 overweight, hyperlipidemic adults (mean BMI, 34)
were randomized to eat a low-carbohydrate diet (starting at <20 g/day of
carbs, plus nutritional supplements) or a low-fat diet (<30% of daily energy
from fat, <300 mg of daily cholesterol, and intake of 500-1000 kcal/day less
than usual). Both groups received exercise recommendations and support at
group meetings. The retention rate was significantly higher in the low-carb
group than in the low-fat group (76% vs. 57%). By 24 weeks, low-carb dieters
had fared significantly better than low-fat dieters in mean weight loss
(-12.0 kg vs. -6.5 kg), triglyceride change (-74 mg/dL vs. -28 mg/dL), and
HDL change (+5.5 mg/dL vs. -1.6 mg/dL); LDL changes were similar in the two
groups.
In another study (a 1-year follow-up of previously reported 6-month results;
Journal Watch Cardiology Aug 8 2003), 132 severely obese adults (mean BMI,
43; about half with hyperlipidemia, about 40% with diabetes) were randomized
to eat a low-carb diet (</=30 g/day of carbs) or a conventional calorie- and
fat-restricted diet (intake of 500 kcal/day less than usual, </=30% of
calories from fat). Both groups received support at group meetings. At 1
year, the low-carb and low-fat groups did not differ significantly in
retention rates (69% and 63%) or mean weight loss (-5.1 kg and -3.1 kg).
However, low-carb dieters fared significantly better than low-fat dieters in
changes in mean triglyceride levels (-58 mg/dL vs. +4 mg/dL), HDL (-1 mg/dL
vs. -5 mg/dL), and hemoglobin A1C (-0.7% vs. -0.1%); LDL changes were
similar in the two groups.
Comment
Results from these studies should mitigate concerns about adverse lipid
effects of low-carbohydrate diets, and even suggest some benefit. Some
caveats are that dropout rates were high (particularly among low-fat dieters
in the shorter study), dietary adherence was suboptimal, and (in the longer
study) 6-month weight-loss advantages in the low-carb group eventually were
reduced. Nevertheless, one can no longer dismiss low-carbohydrate dieting as
fad. An editorialist recommends encouraging overweight patients to engage in
regular physical activity and to experiment with various diets, including
low-carb, with an emphasis on healthy sources of fat and protein.
