Abstract

Non-nutritive sweeteners (NNS) are suggested to lower Energy intake in the diet, but they 11 have been paradoxically involved in the epidemic of obesity and Type 2 diabetes. Stevia is the least 12 studied sweetener. This study aims to investigate the effect of stevia on postprandial glucose levels, 13 appetite and food intake. Methods: Thirty participants (20 females/10 males; 26.1 (10.56) years; BMI 23.44 (3.42) Kg/m2 14 ) took part in a three-arm crossover trial where they received preloads of water, 15 sugar (60g) and stevia (1g) on 3 different days, followed by an ad-libitum pizza lunch. Breakfast was 16 standardized. A one-day diet diary was collected on each test day. Visual analogue scales (VAS) 17 were used to assess subjective feelings of appetite. Blood glucose samples were collected at 30- 18 minute intervals until 120-min post lunch. Results: Energy intake did not significantly differ 19 between preloads for ad libitum meal (p=0.78) and overall day (p=0.33). VAS scores for hunger and 20 desire to eat (DTE) were lower following stevia preload compared to water (p<0.05). After adjusting 21 for the sugar preload Calorie content, postprandial glucose levels did not significantly differ 22 between interventions. Conclusion: Stevia lowers appetite sensation and does not further increase 23 food intake and postprandial glucose levels. It could be a useful strategy in obesity and diabetes 24 prevention and management.
