Laughing, I came looking for carb count of scapes for exactly this reason! I don’t normally experience gassiness while in ketosis.
I found ‘garlic stems’ for sale in the asian supermarket. I had only encountered garlic scapes once before when I belonged to a farmers food co-op. I was so excited and figured they would be of low-carb content since they were above ground greens.
I roasted them with pork neck bones. They were deliciously sweet and savory at the same time. I did notice I felt unusually full the rest of the evening.
I woke up this morning sounding like a one-woman pipe band!
I can confirm garlic scapes make you gassy!
In terms of carb content, based upon taste, I kept thinking they tasted very sweet, reminding me of carmelized onions.
Based on your experience, maybe the amount of fiber offsets the carb content. I hope so, because I have 3 servings left of tender neckbone meat and garlic scapes waiting to be enjoyed!
