Another Blow To High-Carb Diets
A review paper looking at the effectiveness of low-carbohydrate diets versus low-fat diets has recently been published in the British Journal of Nutrition. This paper is one of the first challenges to the long held belief that low-fat, high-carbohydrate diets are the most efficient method of losing weight, which are currently recommended by the Government and other Health agencies.
In a nutshell, what this paper did was to review and analysis previous studies to compare the outcomes of both types of diets in terms of body weight, triglyceride levels, and HDL- and LDL- cholesterol levels. The end result was that these markers improved, and were more beneficial, for the participants following the low-carbohydrate ketogenic diet.
This will come as no surprise to those who have been reading previous research published in the Low-Carb/High-Protein domain. This most recent study confirms the message that substituting carbohydrates for protein and fat does not lead to adverse health.
Unlike previous studies in this area, this review looked at studies without using date or language restrictions. Hence a broader spectrum of studies was incorporated into the review, meaning less biased results.
What is disappointing however is that - notwithstanding the results published and the previous published studies - there is still a consistent fear that a low carb diet has hidden health problems whilst no evidence of these fears has ever been published.
