T3 and T4 increase all aspects of carbohydrate metabolism. Protein Metabolism. Iodothyronines stimulate both protein synthesis and degradation. High levels of T3 and T4 will result in more protein degradation compared to protein synthesis. This will result in a fall in muscle mass and body weight. Iodothyronines play an important role in normal growth and development.
