Recently I have been doing cardio on an empty stomach first thing in the morning to maximise fat burn.
To reduce lean mass loss I always take glutamine and BCAA's before my cardio.
My question is this; I realise after fasting during sleeping through the night your first meal of the day kick starts your metabolism. However, after sleeping and cardio I go approx 10-11 hours without eating so would the Glutamine and BCAA's act the same as your first meal in the sense of kick-starting your metabolism?
I always have a slow-digesting protein shake with EFA's before I go to bed to help prevent the muscle breakdown through the night.
I think you need a more significant amount of calories to 'kick start' your metabolism. This is why anything less than 100 calories or so should never be counted as a meal.. I don't believe it really helps to keep your metabolism spinning
