I am trying to work out every once in a while. I am running two times a week, doing a few workouts from skimble, doing a little yoga/pilates or butt/belly workout. During the week I use my bike very often. Every day a few minutes of workout.
My problem is that I am always tired and exhausted even though I did nothing all day long. Since a few weeks I am suffering from binge eating which should provide lots of energy. But I am just exhausted and not gaining muscle weight but fat. What's wrong with me
Make sure you have a balanced diet with proper nutrition levels.
Your daily calory intake may be too low for your daily activities - esp. with regards to carbohydrates. Use one of the many apps out there and log what you eat and drink. If you're somewhat around or even below 1200 (just an educated guess, check out Scotty K's topic about what to eat to lose or gain weight for personal figures) and your carbs are below 30% it's definitely one of the reasons.
Go visit the doctor, because it could be anything.
