Feels like you are not getting energy from food?

There are many different reasons why you could feel like food gives you no engery. If you still feel hungry after you eat, you may need to eat more, or you could have a parasite that's absorbing all of your nutriets. However, if you feel tired all the time, it could stem from a lack of sleep simply stress or a lack of engery. If the problem persists or becomes severe, then you should see your doctor.
