Interval training is anaerobic and is no different to resistance training in this sense. Do you wait 30-60 minutes before chugging down your shake after a heavy weights session? Hell no.
Aerobic stuff like jogging doesn;t provoke the same hormonal response and uses different bioenergetic pathways than anaerobic training. As far as this goes i'd still eat straight away, but if i had to wait a bit it wouldn;t bother me so much.
Another thing, although it depends on the type of diet you're doing and the structure of the entire thing, but i don;t have carbs after any cardio work. I use protein and fat. If you put sugar into your blood then you're just inhibiting the hGH release that cardio, and especially HIIT, releases. I'm not saying taking in carbs after cardio will stop you losing fat, but why shun a perfect opportunity to maximise fat burning potential? (for anyone unsure, hGH promotes fat burning from adipocytes [fat cells] as opposed to sugar burning [including muscle cells])
