The Effect of Food Supplements on Food Intake and Gut Hormone Levels
February 27, 2020 updated by: Queen Mary University of London
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.
