“Stopped drinking fruit juice years ago - it is a blast of sugar to the system.

At least with whole fruit, you get fiber which slows down the sugar.

Coming from a family of diabetics, none of us need that sugar blast - not sure anyone does.”

Sugars are carbohydrates, and your body needs carbs and sugars. Your brain requires around 130 grams of glucose every day to ensure it operates smoothly. Energy from carbs is essential to your body’s function.

It is recommended that you get less than 150 calories a day from added sugars, which is about 36 grams of sugar. To put it in perspective, a 12 oz. of cola has around 40 grams of sugar. Getting your daily sugars from whole foods like fruits and vegetables provides you with more nutrients than a can of soda. So, choose your sugars wisely.‌

We carnivores eat ZERO carbs, yet our brain works perfectly. Your number of 130 g/day of glucose may be true, but only with a standard diet, which proves to have been devastating to our health in term of chronic diseases and obesity.
It’s totally false in ketosis, when your brain mostly use ketones which are a much better (no inflammation) fuel than glucose, that’s why carnivore is known for solving brain diseases like epilepsy, brain fog, Alzheimer...
So no, energy from carbs is NOT essential, neither for the brain, nor for the body (a lot of high performance athletes are carnivores, see eg Dr Paul Mason testimonies).

Carbs are a subpar food for humans. The idea they would be “essential” to us is baloney (pardon the pun given that baloney is better than any carbs possible), if not borderline criminal considering the official guidelines still recommend them for diabete patients.
