Everyone has to basically find their “sweet spot” when it comes to carb intake. And many factors influence this: how you train, genetics (ectomorph vs. endomoph, using that old terminology), where you’re coming from (former fat boy vs. lifelong lean athlete), type of carbs (potato vs junk food), etc.
And then there’s the issue of workout carbs. The best ones, like those in <a href="http://www.t-nation.com/store/products/plazma"target=“new”>Plazma and <a href="http://www.t-nation.com/store/products/mag-10"target=“new”>Mag-10 don’t behave like whole food carbs and it’s very tough, if not impossible, to gain fat from them. You just can’t count them the same way as you do rice and other whole foods.
Then of course you have the effects of <a href="http://www.t-nation.com/store/products/indigo-3g"target=“new”>Indigo-3G, which partitions carbs toward muscle gain instead of fat storage, meaning that our old ideas about how many carbs are right for us get thrown out the window because Indigo changes those rules. For example, I had to stay about 100-150g of carbs per day or I’d get fat before Indigo. Now I stay leaner eating 3 times that many.
So all that taken into consideration, you’ll see how you have to experiment a little. We used to tell people to start around 200-300g of carbs per day when using Indigo-3G, and workout nutrition like Plazma counts as part of that very general guideline. Some found that 200 was best for them, others found there almost was no top limit of carbs per day when using Indigo.
