Low-carb diet reduces HbA1c in Japanese study
With the rising interest and acceptance of a low-carb diet for improved blood glucose management, more studies from around the world are looking to unearth just how effective a treatment it can be. One team of researchers looked into the efficacy of using a low-carb diet to help people in Japan with poor glycemic control.
The study looked at 66 people with type 2 diabetes. They all had relatively high HbA1c levels of 7.5% or over.
The participants were split and randomly assigned either a low-carbohydrate diet (130g of carbs per day) or a more traditional calorie-restricted diet.
Each group stuck to their diets for six months, and at months one, two, four and six, they were each given personal nutrition education in order to help them stick to the diets effectively.
It was found that the low-carb diet helped improve HbA1c, reducing it on average by 0.65%, and BMI was reduced by 0.58kg/m2.
On the other hand, it was found that the calorie-restricted diet didn’t benefit HbA1c in the participants at all and BMI was reduced by a lesser degree than by the low-carbohydrate diet.
The results suggest that in the Japanese population, a low-carb diet is better for helping people with type 2 diabetes to manage their blood sugar levels, and bring down their HbA1c levels. This would have long term benefits, and could even help people to avoid complications. This is compared to a calorie reduction diet.
The discrepancy shows that cutting down on carbs can benefit health more than focusing on calorie cutting.
