According to a study published in the Annals of Internal Medicine,
looking at 150 otherwise healthy adults, at 12 months, the low-carb
group had lost 3.5 kilograms more than the low-fat group, even though
caloric intakes were similar. The low-carb group also saw greater
improvements in body composition, CRP levels, HDL cholesterol, and
triglycerides.
