i was thinking and wouldnt this plan make cardio very effective in burning fat but limiting muscle loss, after your workout take my shake of 50 grams whey, 75 grams dextrose, then for my cardio go run 30 min. wouldnt this keep my postworkout shake immediately after workout, i have heard it takes about 30 min for the dextrose and whey to absorb so the cardio would still use fat as energy source, and around 30 min to end of cardio the shake will start to be used for energy and get cortisol levels down to prevent muscle loss?? would this work or do i have something wrong?
