Iron is needed to produce red blood cells, which transport energy and oxygen to your muscles. Low iron levels can cause your metabolism to slow down, leading to fatigue, appetite loss, anemia, and many other health problems. The more iron you have available, the more red blood cells your body can produce. Eat more beef, oysters, lamb, poultry, fish, lentils, chickpeas, tofu, and legumes to get more of this essential nutrient.
