Broccoli, brussel sprouts, kale, spinach. Those are your greens high in nutrients.
Meat with fat on it. You burn the fat to get your energy, not carbs. Animal fat is good for you. The healthcare system preaches animal fat is bad. It’s a lie. Carbs in the diet make people overweight, and bring on diseases, so they can milk you for life $$$$$ from “treating” you.
