Research on intermittent fasting for people with type 2 diabetes or at risk for type 2 diabetes is still preliminary, with much of the research in this area still being conducted in animal models. However, there are promising pilot study findings coming out of Dr. Krista Varady’s lab related to improved glucose regulation over time. Recent studies have found that IF may have a greater positive impact on insulin resistance than traditional calorie restriction diets. While more research is needed, diabetics and pre-diabetics may stand to benefit the most from IF.
All diabetic and pre-diabetic individuals should work with their primary care physician before and while practicing fasting in any form, as this intervention may alter their medication needs and other symptoms.
