• Interventions: Dietary Supplement: Lauric Acid, Perilla Oil and Diindolylmethane

• Registration Number: NCT04292236
• Lead Sponsor: Queen Mary University of London

Brief Summary

When a meal is eaten, nutrients activate the release of hormones from the bowel into the blood stream. Normally there is a large amount of hormone released, which tells the brain that an individual is full and to stop eating. When people gain weight and become overweight or obese, these hormone signals are reduced, resulting in these people eating more and gaining more weight. This study is investigating mechanisms which may break this cycle by using particular nutrients to restore reduced hormone levels.
