According to a study published in the Journal of Clinical Endocrinology & Metabolism of the Endocrine Society, patients who completed an intermittent fasting diet intervention attained complete diabetes remission, indicated by an HbA1c (average blood sugar) level of less than 6.5% at least a year after ceasing diabetes medication.

The use of intermittent fasting as a weight loss strategy has grown in popularity in recent years. Dr. Dongbo Liu, Ph.D., of Hunan Agricultural University in Changsha, China, stated that patients with diabetes can achieve remission if they reduce weight by altering their eating and exercise routines.

In the study, 36 diabetic patients participated in a 3-month intermittent fasting diet intervention. The researchers discovered that 90% of participants, including those who received insulin and blood sugar-lowering medication, decreased their diabetes medication after the diet.

The findings of the study also showed that 55% of these participants maintained their diabetes-free status after going into remission for at least a year. The study also showed that the claims that people who have had diabetes for a shorter amount of time can only attain remission after 0–6 years were false. They pointed out that 65% of the participants were diagnosed with diabetes more than 6 years ago.

Dr. Liu further added that for many people striving to adequately control their diabetes, the expense of diabetic drugs is a barrier. However, medicine costs dropped by 77% among participants who underwent intermittent fasting.
