Is there anything wrong with eating 2-3kg of vegetables a day if that's what it seems to take to feel satiated?
Always very green and low glycemic vegetable but just quite large quantities. Things like green beans, cabbage, broccoli, zucchini etc.
Would love to hear your thoughts.
Certainly not wrong by any stretch of the imagination. However, you say that you NEED that much to feel satiated, which may not be the case. If you do not desire to eat that much vegetable matter everyday, you could up your protein or fat to help induce satiety as well.
Go crazy man, almost all vegetables are very calorie-sparce and nutrient-dense. I eat a pretty heaping portion of vegetables with both lunch and dinner. Just be careful how many green vegetables you eat, they can disagree with some people. As much as I love b-sprouts and broccoli, the farts they give me could peel the paint in my apartment.
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!
