Fine tuning starchy meals for optimal cognitive and physical performance

So I've started introducing some starchy carbs (sweet potato, rice) into my diet after stagnating at 10% bf for good 6 months despite attempting to progressively reduce overall caloric intake. I have decided to track my blood sugar levels using a glucometer.

All my readings suggest that my blood sugar levels are well within the normal range however I still get some mental 'heaviness' and a general reduced mental sharpness/calrity following a starchy meal (~50g carbs) despite having an underlying 'strong' feeling. What I mean by strong is that I feel generally much better recovered from my workouts and my workouts themselves are much more intense. I don't however have the mental clarity that I used to get when combining lean game meat with cashews (the version of paleo that gave me best cognition).

Any suggestions/ideas are greatly appreciated.

50g in a single sitting may be too much for you until you acclimate. Start with a smaller amount and build up if your trying to reintroduce. I mean a whole sweet potato is like 30g and I can't eat more than one or two of those/day total

Oh, and sub 10% bf is sorta unnaturally lean. Thats probably why for most people it is so much work to get there. The 10-15 range seems to be fairly healthy and attainable for me, but anything less is just too much effort. Just my experience.

As to cognition vs. athletic performance, this may be one of the instances at least as in your case that you have to choose one with a bit of sacrifice to the other.
