IMPACT OF A 7-DAY ALL-FRUIT DIET ON GLYCEMIC CONTROL AND BODY WEIGHT IN INDIVIDUALS WITH TYPE 2 DIABETES

Background: Type 2 diabetes mellitus (T2DM) is a chronic metabolic disorder characterized by insulin resistance, impaired glucose tolerance, and progressive ?-cell dysfunction, leading to persistent hyperglycemia. Traditionally, individuals with T2DM are advised to limit fruit consumption due to concerns over natural sugars. However, emerging evidence suggests that whole fruits may support metabolic health by improving insulin sensitivity and glycemic regulation. Objective: This study evaluated the short-term effects of an exclusively fruit-based diet on glycemic control, body weight, and overall metabolic well-being in individuals with T2DM. Methods: Thirty-two adults with type 2 diabetes participated in a 7-day all-fruit dietary intervention. Participants consumed 3–4 mono-meals of fruit daily, with individual meals consisting of 500 to 1000 grams of fruit. Self-reported data on dietary intake, symptoms, fasting blood glucose (FBG), and body weight (BW) were collected pre- and post-intervention for analysis. Results: The intervention resulted in a mean weight loss of 2.7 kg and an average decrease in FBG of 1.02 mmol/L. No serious adverse effects were reported. Conclusion: A short-term, all-fruit diet appears to be safe and effective in improving glycemic control and reducing body weight in people with T2DM. Further research with larger sample sizes and controlled conditions is warranted to validate these findings and assess long-term outcomes.
