Here is an article that explains why having carbs post workout isnt a must.
What do you guys think?

It did a study that had 3 diff groups. Each group ingested same protein pwo, but diff carbs.
Group 1: no carbs,
Group 2: .15 kg/body weight
Group 3: .6 kg/body weight
It says the study shows no difference in protein synthasis and that ingesting carbs pwo can actually be counter productive:
Growth hormone levels are elevated after resistance training. It's well known that as insulin levels increase in the body, growth hormone decreases. A large spike in insulin will occur with the ingestion of high GI post-workout carbs. Therefore, it would seem that carb intake after resistance training may be counter-productive.
Also, its input on fat burning:
Obviously if you are taking time to refill your muscle glycogen stores with carbohydrate after a workout, you are reducing the amount of fatty acids your body will use to provide the energy it needs.
In order to keep fat-oxidation (using fat for energy, whether from body-fat or food) at maximum levels, it would make sense to leave the carbs out of your post-workout shake. In doing so you encourage the body to tap into it's stored fat.
Anyone agree?
