And given the choice, I definitely choose low-carb.
But I don’t consider carbs from green leafy-vegetables or low-glycemic berries as “carbs”. So eat as much leafy veggies as you want, especially anything high in potassium, which very few people get enough of.
People MUST still eat those. I don't have an issue with weight gain, so I can eat all the berries, veggies and salad I want... but everyone is different. Goals are different too.
What you posted previously, about getting energy from either ketones or carbs, period, is essential knowledge. Understanding that changes everything.
