Peptide YY
Another gut hormone that suppresses appetite is peptide YY (PYY). Low peptide YY levels are seen in obesity and before the beginning of type 2 diabetes, and both factors may lead to weight gain. Sufficient levels are thought to have a key function in reducing food intake and reducing obesity risk. There has been some research into using peptide YY as an obesity medication, with the goal of reducing the appetite of obese people.
To maintain a healthy amount of PYY in your body, you can start with maintaining a well-balanced diet. PYY levels and fullness may be improved by eating a high-protein diet. The paleo diet, which is high in protein, fruits, and vegetables, may also raise PYY levels. While there is conflicting evidence about exercise and PYY levels, being active is usually helpful to one's health.
