RESUMO
Background and aims: Meals with high protein and fiber could reduce weight and improve diabetes risk factors. Isomalto-oligosaccharide (IMO), a form of dietary fiber, could induce the afferent signal that causes appetite suppression. However, the direct effect of fiber supplementation in the form of IMO combined with a high-protein diet (HPF) on those parameters is still unknown. This study aims to investigate the effect of HPF on anthropometric parameters and blood glucose regulation of healthy subjects. . Methods: Thirteen healthy subjects were given a hypocaloric high protein diet (HPD) mixed with their prepared meals for two weeks. Followed by the HPF diet for another two weeks. Their anthropometric parameters, such as body composition (total body weight, body fat percentage, and fat-free mass), BMI and waist circumference, and fasting plasma glucose, were measured. Results: Compared to pre-intervention, HPF could significantly (p ≤ 0.004) reduce the anthropometric parameters and fasting plasma glucose. Compared to HPD, HPF could significantly (p ≤ 0.005) reduce more total body weight, body fat percentage, and BMI. In addition, HPF could induce more satiety than HPD (higher VAS score). Conclusion: HPF could improve the subject's anthropometric parameters which is obviously beneficial in preventing the risk of developing diabetes.
RESUMO
BACKGROUND AND AIMS: High-performance (HP) inulin, a dietary fiber consists of more than 10 fructose polymers, have been shown to reduce post-prandial glycaemic response (PPGR) and could prevent the occurrence of Type-2 diabetes mellitus (T2DM). Currently, there are no data on whether pre-meal HP inulin supplementation could decrease PPGR. METHODS: 8 healthy adults consumed 20 g of formula that contain 60.2% inulin (w/w) dissolved in water. Blood glucose was measured in fasted participants and at 30-120 min after starting to eat a prepared meal. This test was repeated every week with different supplement formulas. CONCLUSION: pre-meal HP Inulin formula supplementation could suppress the post-prandial glycaemic response.
