I'm currently cycling through keto right now, so anything beyond 30-35g of additional carbs (must be within 30 minutes after lifting) on top of a 25g/day typical load could break several days of progress. I typically add the additional carbs after workout with a blueberry greek yogurt smoothie with a scoop of coconut oil, almond butter, and protein powder. I follow that an hour later with a protein rich lean meat or fish. That said when I stop my current cycle with keto I will probably bump it to 45g - 60g after a workout.

I've pretty much turned to recognize most people literally eats shit that even bacteria won't touch because the food is more akin to plastic than snack (anything fried in or cooked with the following oils: vegetable, peanut, corn, sawflower, sunflower, or grapeseed... olive oil as well but only if it was used for cooking - it's fine to consume olive oil as a topping or garnish if it hasn't ever been heated to its smoke point). Wheat in any noteable quantity causes a "leaky gut" syndrome to a wide range of varying degrees (from unnoticeable reaction to the other end - see people with celiac disease - but all people develop chronic inflammation with constant wheat intake) so when not on keto I still avoid wheat derived cabs. Still maintain my stance on sugar previously stated. To expand on why I hate sugar it's to avoid the incredible insulin spike it causes so my body is more sensitive to insulin after meals and sugar is addictive (if somewhat mildly)... I like not having metabolic syndrome or tendencies towards vices.
