I would have to disagree with those numbers posted....
for a 200 lb. individual, a high carb, moderate carb, and low carb would be much more, with a keto diet carb levels being a separate matter all together...
High: 2-2.5 g /lb. of weight (ie 400-500 g)
Moderate: 1-1.5 g/lb of bw (ie 200-300 g)
Low: .5 g/lb of bodyweight (ie 100 g)
keto: 10-50 g (depending on how low you need to go to reach ketosis)
At 200 g of carbs at day, it's doubtful one could bulk up efficiently.....the overfeeding of carbhydrates is essential when bulking.....no matter how protein you eat....the lack of sufficient carbs would cause your body to use all the protein you would in lieu of the carbs as an energy source of a source of glycogen (and a very inefficient source of glycogen at that...)...a large carb intake will spare the protein you eat for muscle repair......when dieting, if you respond well to keto diets, then carbs can be lowered, but fat needs to be drastically increased.
