Protein-Rich Foods
Foods that are high in protein levels offer you a dramatic increase in metabolism for at least a couple of hours. The main reason for that is that they demand your body to use more energy in the digestion process, which helps you burn more calories overall.
Recommended foods: fish, eggs, dairy, nuts and seeds.
Iron, Zinc and Selenium-Rich Foods
Each of these elements plays a different role in your digestion process, as well as building up your immune system. However, when combined, they improve the functionality of your thyroid gland, which regulates your metabolism.
Recommended foods: seafood, nuts, meat and legumes.
