Abstract
Background and objective: LN19183 is a proprietary, synergistic combination of Citrus aurantifolia fruit rind and Theobroma cacao seed extracts that increased resting energy expenditure (REE) in high-fat diet (HFD)-fed obese rats. The objective of this study was to validate the thermogenic potential of LN19183 in obese Sprague Dawley (SD) rats and to assess its clinical efficacy in a proof-of-concept, randomized, placebo-controlled, cross-over human trial.
Methods: In the rat study, HFD-fed obese rats were supplemented with either HFD alone or with 45, 90, or 180 mg LN19183 per kg body weight (BW) for 28 days. In the human study, 60 overweight adults (male and female, aged 20-39 years) were randomized. Subjects took LN19183 (450 mg) or a matched placebo capsule on two consecutive days in phases one and two of the study, separated by a 10-day washout period. In each phase, on day 1, REE at pre-dose, 60-, 120-, and 180-min post-dose, and on day 2, metabolic rates at pre-dose and post-dose during and 20 min after exercise were measured using indirect calorimetry.
Results: In rats, LN19183 significantly increased REE, reduced BW gain and fat masses, and increased fat and carbohydrate metabolism marker proteins including beta 3 adrenergic receptor (β3-AR), phospho-AMP-activated protein kinase (AMPK), glucagon-like peptide-1 receptor (GLP-1R) in the liver, and serum adiponectin levels. Furthermore, LN19183-supplemented human volunteers increased (P < 0.05, vs. placebo) the metabolic rates at rest and with exercise; their fat oxidation was increased (P < 0.05, vs. placebo) at rest and 20 min post-exercise. The groups' systolic and diastolic blood pressure (BP), heart rates (HR), and safety parameters were comparable.
Conclusion: These observations suggest that LN19183 is a thermogenic botanical composition with no stimulatory effects on BP and HR.
期刊介绍:
Food & Nutrition Research is a peer-reviewed journal that presents the latest scientific research in various fields focusing on human nutrition. The journal publishes both quantitative and qualitative research papers.
Through an Open Access publishing model, Food & Nutrition Research opens an important forum for researchers from academic and private arenas to exchange the latest results from research on human nutrition in a broad sense, both original papers and reviews, including:
* Associations and effects of foods and nutrients on health
* Dietary patterns and health
* Molecular nutrition
* Health claims on foods
* Nutrition and cognitive functions
* Nutritional effects of food composition and processing
* Nutrition in developing countries
* Animal and in vitro models with clear relevance for human nutrition
* Nutrition and the Environment
* Food and Nutrition Education
* Nutrition and Economics
Research papers on food chemistry (focus on chemical composition and analysis of foods) are generally not considered eligible, unless the results have a clear impact on human nutrition.
The journal focuses on the different aspects of nutrition for people involved in nutrition research such as Dentists, Dieticians, Medical doctors, Nutritionists, Teachers, Journalists and Manufacturers in the food and pharmaceutical industries.
