10 Signs You Are Not Eating Enough

8. Constantly thirsty

If you are not getting enough calories, there is a chance you are also not getting enough water. Although many people think we only get water from fluids, we also hydrate our bodies with the food we consume. Moreover, the food we eat provides electrolytes such as sodium, potassium, and magnesium, which all affect thirst. If you feel thirsty, have dark-colored urine, are not peeing enough, have dry mouth or dry skin, feel tired, or have a headache, you might be dehydrated.
