When you sleep you have a respiratory quotient of 0.7 or so(RQ is the amount of CO2 expired divided by the amount of O2 inhaled). At this value, I’ve been taught that your body is burning 100% fat as fuel. If 100% fat is being burned, where does the notion of sleep being such a catabolic state come from?
Furthermore, when dieting, if Fat is the only fuel source being used while sleeping, would it not make sense to sleep on an empty stomach and supplement with glutamine peptide (mixed with water) and ZMA. The two raise IGF-1 and glutamine is anti-catabolic. ZMA will improve endocrine function that is sometimes adversely effected when dieting and both will help with immune function as well.
Does it make sense to forget the pre-bedtime snack in favor of glutamine and ZMA when fat loss is the goal? I’ve had favorable results in the past. What are your thoughts?
