I never said cardio after training wasnt a good way to lose extra fat...i said cardio after training when u should be consuming your postworkout meals is counterproductive. It interfers with the recovery process, which alone is responsible for growth.
And I dont believe anyone should ever cut out high gi carbs postworkout. Science has proven this:
Don’t underestimate the importance of carb timing for triggering glycogen synthesis after a workout. Not only is a bodybuilders total work capacity correlated directly to the amount of glucose/glycogen held within muscle, the process of glycogen accumulation triggers an immediate “cell volumizing” effect, a potent anabolic response. The right carbohydrate timing strategy will amplify the anabolic stimulus of resistance training.[1,3,20]
The research on carbohydrate intake and weight lifting shows that the consumption of a carbohydrate supplement just before (or during) an intense workout can save valuable muscle glycogen stores from complete depletion, as well as enhance total lifting capacity during the workout. [15,16] While training without using a carb supplement before weight training results in muscle carb depletion, and poor weight training performance [14], supplementing just before or during training, results in only a 13.7% decrease in muscle glycogen content and more weight lifted, for more reps in every working set![16-18]
A carbohydrate supplement consumed immediately before or after weight training is shown to directly affect the hormonal response. Taken before training, a carb supplement will maintain blood sugar levels, and restore insulin levels. The presence of insulin is vital for stimulating muscle protein synthesis rates. [19] A carb supplement taken immediately after training increases insulin concentration while decreasing 3-methylhistidine and urea nitrogen excretion (all examples of reduced muscle breakdown).[20]
Consuming a carbohydrate supplement after resistance training also enhances the growth hormone response and reduces circulating cortisol concentrations.[21,22] Cortisol is the number one glucocorticoids hormone that is responsible for muscle breakdown. Carb timing stops cortisol elevation dead in its tracks.
