What do you guys eat right before/after cardio?

[Charles Ray]

If you're looking to burn just fat what do you eat before and after cardio?

Before cardio eat nothing? Or ingest 20gm of a protein shake to save muscle?

After cardio only drink water for an hour afterwards? Or drink some simple carbs with extra water to replenish the glycogen that you've lost?

If cutting: Glutamine (5-10g) before cardio on empty stomach
Then lots of water and eat in 1 hr

If not cutting: Glutamine before
30 minutes protein and carbs
