3. Fatigue Cause No. 3: Not Enough Fuel
Eating too little causes fatigue, but eating the wrong foods can also be a problem. Eating a balanced diet helps keep your blood sugar in a normal range and prevents that sluggish feeling when your blood sugar drops.
Fix: Always eat breakfast and try to include protein and complex carbs in every meal. For example, eat eggs with whole-grain toast. Also eat small meals and snacks throughout the day for sustained energy.
4. Fatigue Cause No. 5: Depression
You may think of depression as an emotional disorder, but it contributes to many physical symptoms, as well. Fatigue, headaches, and loss of appetite are among the most common symptoms. If you feel tired and “down” for more than a few weeks, see your doctor.
