Personally I think extemely low carb diets are nonsense, unless you're trying to get competition b/f levels.
I do NO cardio and eat carbs for my first 6 meals. The last 2 meals are protein and veggies. Each of my first 6 meals consists of either 1-2 cups of brown rice or rolled oats.
I don't know my actual b/f level, but I can see the veins on my serratus. I would guess around 7-8%.
I'm also 34 y/o, so my metabolism is supposed to be slower than most peeps here. I gain fat easily, as well as lose it easily.
I never get hungry and never get cravings. I never cheat on my diet because I don't feel the need.
It's all about eating sensibly.
