Low carb diets good for weight but not LDL
A recent randomised, controlled study has compared the effects of low vs high carb diets on metabolic profile. This was carried out in a small sample of obese men and women using diets that contained either =20g/d carbohydrate (low) or 55% total energy as carbohydrate (high).
After six weeks of consuming diets containing different levels of carbohydrate and fat, subjects’ metabolic profiles were compared. All participants lost similar amounts of weight but LDL ‘bad’ cholesterol levels only decreased in those eating the high carbohydrate diet. Therefore, it is possible that low carb diets are not suitable for LDL cholesterol reduction. More research is needed to study this further.
