The question of eating before exercise has some considerations to it.  The main one would be what time of day you are working out.  Fasting before working out is fairly easy if you are an early riser and hit the gym in the morning.

Yes and no

There’s been some good scientific study and it appears there are benefits in both working out fasted or fed.

  • One study showed no significant difference in actual performance of participants in aerobic exercise of under an hour either way.
  •  Another focused on HIIT high intensity interval training and also saw no difference between fasted and fed participants.

Fat burner

There is evidence that exercising while fasted increases the body’s ability to burn fat for fuel.  One study showed as much as a 20% increase in fat burning.  Other studies have shown an increased ability of the muscles to burn fat and maintain desirable blood sugar levels.

Carb burner

Some people may find that they get more from their workouts eating before and using more carbohydrate for fuel. 

We suggest trying both and find out what works best for you.

Most importantly

The most important factors with exercise are getting good nutrition, proper sleep and being consistent with your workouts.
