CBD may affect metabolic control and energy intake. However, there is currently little data regarding these specific outcomes in humans. Therefore, this study will investigate whether four weeks of supplementation with 60 mg/day CBD affects energy intake at a single meal, and or fasting blood-based markers of appetite regulation and metabolic health. Healthy, adult volunteers will be assigned to placebo or CBD supplementation, in a randomized controlled trial, comparing changes in outcomes across the supplementation period between groups.
