Abstract
Background: Obesity is a global health problem, increasing susceptibility to Type 2 Diabetes (T2DM) and Cardiovascular Disease (CVD). Varieties of products have been proposed for treatment with varying degrees of success. Recent studies, suggested Oligonol; an optimized phenolic product mixture from Lychee Fruit Polyphenols (LFP); as such treatment in Japanese population.
Objectives: We aimed to investigate the effect of oligonol on weight, insulin resistance by (HOMAIR), lipids profile, leptin, Adiponectin, and resistin in healthy overweight and obese Saudi females.
Subjects and Methods: 60 Saudi healthy overweight and obese females were enrolled in a double blind case/control study to take either Oligonol or placebo for 12 weeks without dietary or lifestyle restrictions. Weight, height, Waist Circumference (WC), hip circumference (HC), and blood pressure were measured, and fasting blood samples of participants were taken before, and at the end of study. Total cholesterol, HDL-cholesterol, triglycerides, glucose, insulin, leptin, adiponectin, and resistin were measured. LDL- cholesterol, HOMA-IR were calculated by equation.
Results: 47 subjects completed the study, 25 in placebo group, and 22 in Oligonol group. No ill effects were noted in any participant. Oligonol reduced means of serum triglycerides (P=0.008), and resistin (P=0.045) significantly. In addition, no weight gain was noted in oligonol group, unlike placebo group which exhibited significant increase in mean weight (P= 0.036), WC (P=0.027), HC (P= 0.047), and leptin (P <0.001).
Conclusion: Oligonol could be suggested as future hypolipidemic and weight controlling agent for overweight and obese Saudi females.
Keywords: Abdominal obesity, adiponectin, insulin resistance, leptin, lipid profile, oligonol, resistin.

Functional Foods in Human Health and Beyond
Foods are important source of nutrients including carbohydrates, proteins, lipids and other minerals. Furthermore, the functional foods are those agents that have additional components that are essential supports to the body in terms of antioxidant and pharmacologically active agents. The predominant functional foods are of plant in origin, whereas some ...read more
Harnessing Bioactive Compounds from Food Waste: Sustainable Extraction Strategies and Health Applications
Food waste presents a significant challenge across the postharvest cycle, from agricultural production to distribution. However, within this waste lies a treasure trove of bioactive chemicals that hold immense potential for nutraceuticals, functional foods, and postharvest additives, including antimicrobials. Various extraction methods, such as solvent extraction (SE), supercritical fluid extraction ...read more
