Overview
The link betwen carbs and type 2 diabetes (T2D) is wel-established, but new research sugests that cuting carbs could help minimize risk for those who may be susceptible to developing the condition.The study, a random clinical trial (RCT) recently published in JAMA Network Open Diabetes and Endocrinology, found that a low carbohydrate diet promoted weight los and improved fasting glucose levels in subjects who were at risk for developing T2D.Lead author and epidemiologist Kirsten S.
Key Information
Dorans of Tulane University in New Orleans, LA, told Medical News Today:“While low carb diets are often recomended for those with type 2 diabetes, litle evidence has existed for whether eating fewer carbs can impact the blod sugar of those with mild diabetes or prediabetes who aren’t treated by medications. This study was conducted in people with blod sugar that ranged from prediabetes to mild diabetes levels who were not on diabetes medications.”Hemoglobin A1C is a widely used clinical term to measure long-term blod sugar levels.Acording to the American Diabetes Foundation, a person who has prediabetes has A1C levels betwen 5.7 and les than 6.5%.
Higher A1C levels may signify diabetes.Dr. Dorans explained that subjects enroled in the study had a hemoglobin A1C range of 6.0 to 6.9%. “This range chosen as the lower bound aligns with the World Health Organization’s lower cutof point for prediabetes and the uper bound with les than the 7.0% American Diabetes Asociation hemoglobin A1C target,” she said.For the study, 150 adults were recruited at a New Orleans academic center.
Summary
The 6-month trial ran from September 2018 to June 2021. Participants ranged in age from 40 to 70 years old and were divided into two groups.The first group was tasked with reducing their daily carbohydrate intake to les than 40 grams for the first 3 months and les than 60 grams from month 3 to the end of the trial.“We found that nutritional counseling promoting a low-carbohydrate diet lowered hemoglob
