I Think carb cycling seasonal is the way to go. Back long ago we didn’t have fridge’s. Long ago we Hunted in the fall eating wild berries and getting a little weight on and stock up on meat and put it on ice for the winter. While Hell freezes over you get into ketosis and heal and rest. Spring comes you might fish since a lot of game is still sleeping. Then Summertime comes and Apples and berries maybe watermelons were growing this wold be a treat. This would give you sugar yes but ketones would still be in your system and with the fresh water,I bet that would cool you off in the Summer. Even give you that edge for hunting, Honey would be a gold mine to have. When times changes farming was a smart move. Grow food for your pray and kill them off one at a time and have fresh food anytime. This would give you time to build, invent, play chess maybe. We all know Kings in the pasted would eat everything all of the time and get Fat! while the warriors would eat meat and little barely bread and be tough as nails. The way I see it we have a big tank for fat and small one for sugar. Keeping that small one filled half way would be the way to go but still stay into ketosis. I know baby’s drink milk and stay in ketosis and use the sugar in the milk.Their brain is so big and the baby so small that it needs both at the same time. Yes Deer, beef, sardines, pork, chicken soup, eggs, lamb chops, any liver, should be a very healthy diet for anyone. I know giving up the raw goats milk was hard for me. I end up replacing it with wild blue berries. Keeping a cup of them around every week wont hurt. Turning milk into butter was a thing. A lot of hard work for a reason. Having a avocado here and there wont either. Once we started eating what the cows are fed like grains to fatten them up, I wonder why we didn’t think it wouldn’t do the same to us?
