the carbohydrate-reduced diet - more beneficial with respect to cardiovascular risk factors

Here is another study on a low carbohydrate diet and its impact on weight loss and alleged cardiovascular risk factors. The full text is available too.

A randomized controlled trial on the efficacy of carbohydrate-reduced or fat-reduced diets in patients attending a telemedically guided weight loss program


We investigated whether macronutrient composition of energy-restricted diets influences the efficacy of a telemedically guided weight loss program.


Two hundred overweight subjects were randomly assigned to a conventional low-fat diet and a low-carbohydrate diet group (target carbohydrate content: >55% energy and <40%>


In both groups, energy intake decreased by 400 kcal/d compared to baseline values within the first 6 months and slightly increased again within the second 6 months. Macronutrient composition differed significantly between the groups from the beginning to month 12. At study termination, weight loss was 5.8 kg (SD: 6.1 kg) in the low-carbohydrate group and 4.3 kg (SD: 5.1 kg) in the low-fat group (p=0.065). In the low-carbohydrate group, triglyceride and HDL-cholesterol levels were lower at month 6 and waist circumference and systolic blood pressure were lower at month 12 compared with the low-fat group (P=0.005-0.037). Other risk markers improved to a similar extent in both groups.


Despite favourable effects of both diets on weight loss, the carbohydrate-reduced diet was more beneficial with respect to cardiovascular risk factors compared to the fat-reduced diet. Nevertheless, compliance with a weight loss program appears to be even a more important factor for success in prevention and treatment of obesity than the composition of the diet.

I've used a similar diet in the past and was quite pleased with the results. Thanks for sharing this information.

With the amount of diets available I've had a hard time finding ones that work, but I've used ones similar to this and they had the best results. I'm still using them and keeping up with the weight loss.

I've always been confused how this diet works. Thanks for sharing your insight.
