its slightly different.
for HIIT there are NO simple carbs allowed, because as little as 10g (at one time) will substantially lower your results (if taken within 24 hours after working out). keep in mind your GH levels spike during REM sleep, and after HIIT workouts. some HIIT folks bypass the fast carb rule by taking in quick carbs before working out, as their GH levels respike right after - this is usually the early morning HIIT group. this is the only doable way of getting a cheat meal in while pulling off a HIIT routine.
for bodybuilding, simple carbs are optional, though pre/post workout are when most of us take them, and then stick with slower digesting carbs throughout their day. simple carbs will not affect test levels, and really don't make a bit of difference with regards to bodybuilding, other than the amount of fat you're willing to gain by taking too many simple carbs.
also, with regards to bodybuilding and test levels, trans-fat is our devil - as little as 2 grams can substantially lower test levels - hence why fast food is only OK while on cycle (since there's no test levels to lower). though there are plenty of other reasons to avoid fast food while cycling (sodium levels, etc).
