I posted before about a 4:1 ratio of carbs to protein in a post workout meal is a good target ratio. Too much protein in relation to carbohydrate stimulates an enzyme called cholecystokinin (CCK) which can slow your gastric emptying rate, slowing rehydration and recovery after exercise. To offset this effect, studies have shown that a post-exercise meal consisting of a 4 to 1 ratio of carbohydrates to protein is effective.
Of course this can vary from athlete to athlete. I got mixed up and said 40g protein for 100g carb before. Well, this is exactly what Dr. Colgan, a very highly respected scientist of athletic nutrition recomends after weight training.
Bottom line - EAT.
