I think it's helpful to have good alternatives that make avoiding
carbs less like punishment. If you're a chocoholic (like me), a whey protein drink with cocoa and stevia tastes good, has lots of anti cancer ingredients and gives a sustaining energy. Mixing some microwaved unsweetened baking cocoa chips with Stevia and a bit of peanut butter is indulgent without the carbs. You can put it in those mini foil cups for portability.
Seems like most green vegetables are low in carbs. Think salmon with asparagus and olive oil. More punishment please.
