Fuel is needed to promote enhanced muscle building, and if you're not eating often enough or eating in that hour window after working out, your body may start to use muscle as fuel for energy instead. This leads to fat storage, muscle loss, and an inability to build stronger, more defined muscle.
Does exercising on empty stomach burn fat?

Will I lose weight if I don't eat after a workout?

Why do I workout better without eating?
Working out on an empty stomach ensures enhanced fat burning because our body then relies on stored fat for energy since glycogen levels are depleted. This promotes fat loss over time. Further, 'fasted workouts' improve insulin sensitivity making it easier for the body to manage blood sugar levels.
What happen if you workout without eating?
When you exercise on an empty stomach, you may burn valuable energy sources and have less stamina. Low blood sugar levels may also leave you feeling lightheaded, nauseous, or shaky. Another possibility is that your body will adjust to continually using fat reserves for energy, and start to store more fat than usual.
