I have days where I do this. The other day I broke a 26-hour fast with 2 sweet potatoes, 1 spaghetti squash, 30 brussel sprouts, zucchini squash, kale chips, 2 red peppers and 6 eggs. There are other times where I'll go nuts on spinach, broccoli, brussel sprouts, carrots and pretty much anything else I have around. Other days, I'm almost exclusively protein and fat. Vary it.
My only rule with these high-carb feeds with vegetables and roots/tubers is to expect some "fullness" from the fiber. I definitely feel a little fuller/bloated a few hours after these huge meals, but it also gives me a nice reset about 12 hours later with a healthy bowel movement!
