I'm not saying that at all. How many calories are in each respective gram? How is your body processing them? What is your BMR? How many of each are you eating? Both, to some degree are essential. How much are you exercising? If you are going to engage in intense cardio you will need some carbs to fuel you. Michael Phelps eats over 12,000 calories a day when he's training, most of them carbs, yet he stays skinny as a rail. He needs those carbs to fuel his intense swimming regimen. He was also at an age when he probably still had a naturally high metabolism.
My point is, essentially for older people you really don’t need carbs at all, unless you’re training for a marathon or need to do intensive exercise.
Now it’s true, that to make sure you get the nutrients you need, it will require eating some foods with carbs, but the carbs are not the thing you need.
One of the things that Dr. Berg stresses, is that you have to make sure you get in your daily requirement of Potassium, and that comes from eating vegetables. And he also says that your carbs from non-starchy vegetables shouldn’t even count against the limits imposed by the Keto Diet, mainly because the fiber offsets it.
