Yes, I ate spinach. kale, cucumbers or romaine lettuce in one of my meals. I also took potato starch, mixed with inulin which are all fibers.
I’m in quarantine, and I’m now eating a small quantity of yellow lenses (dal) with that one meal. It’s very high fiber but also has carbs. Having been on this diet almost 2 years, I’m fat adapted and will readily burn fat whenever my insulin is low so I make sure I have low insulin periods of time everyday (by doing intermittent fasting for example)
