Babies are growing at an accelerated rate. Lions also have milk as cubs.
Refined sugar is shit but your brain literally needs glucose to function and your muscles need glucose to store glycogen. If you can’t get access to sugar/carbs, your body will adapt and convert fat to sugar but that is less efficient. Athletes at the highest level can’t sustain a carnivore diet.
We tell kids not to eat sugar but human breast milk is like angelic ice cream. It’s so sweet.
