This makes no sense. Why would the body prefer to break down a functional store of energy when has access to a non-functional one?
Pretty sure that’s exactly the purpose (evolutionarily speaking) of fat. It’s an intermittent store of energy to fill in the gaps between the sporadic meals we evolved eating. It just makes so much sense that when food is plentiful (peak season) you want to be able to pack on the fat in order to get you through the cold season when food is scarce.
And it isn't only that. Squirrels even harvest so they got food in winter. We've also learned to maintain foods, such as sushi with rice, or with salt or acid so it wouldn't go rancid. Plus, like I said, there's "winter vegetables" which are high on carbs, low on water.
