LOW CARB VS GRAIN-BASED DIET
In June, the International Journal of Sports Nutrition and Exercise Metabolism presented a case study which had some interesting results. Comparing the effect of a low-carbohydrate with a grain-based diet, there seem to be pros and cons to both approaches.
The authors compared the effects of both diets on body composition, athletic training and performance markers over a 14-day period, with an endurance-trained subject following a pre-scheduled training programme. The low-carb diet consisted of 54.7 per cent fat, 21.5 per cent protein and 23.5 per cent carbohydrate. The grain-based diet consisted of 59.2 per cent carbohydrate, 12.2 per cent protein and 28.6 per cent fat.
But measured showed that the low-carbohydrate diet may lead to less inflammation in the body and improved lactate clearance. It also led to weight loss, with 2.8kg being lost over 14 days, versus 0.6kg gained on the grain-based diet.
This study highlights the need for further examination of diet balance, ideally taking into account the quality of food as well as type, so that more meaningful conclusions can be drawn.
