Weight loss solutions are on the rise, and there is growing interest in natural alternatives to the pharmaceuticals in the market, which are not devoid of relevant side effects. To this end, the objective of the current study was to assess the effects of a botanical-based blend comprised of lemon verbena and hibiscus extracts on weight management, body fat, appetite, lipid, and glucose profiles in an overweight population for 90 days. The volunteers presented significant weight loss in absence of diet (approximately 3 kg, −3.4% total body weight), which coincided with decreased body fat (−1.7%, equivalent to an almost 6% decrease compared to initial value). Body fat was assessed by anthropometry, electrical bioimpedance and DEXA scans. Cholesterol levels were also significantly decreased (approximately 7% decrease). Satiety assessment revealed that the product contributed to increased feeling of fullness and satisfaction after a meal compared to the placebo group, which could contribute to the weight loss observed. Blood glucose and blood pressure levels remained unchanged, which was expected as the volunteers were normoglycemic and their blood pressure was in the healthy range. In conclusion, daily supplementation of a botanical-based blend contributes to weight loss in overweight individuals in absence of diet, while not affecting other parameters that are in the healthy range. This product could be a candidate alternative or add-on to other weight loss products as part of a healthy lifestyle.
