For awhile, a few months in, my veins would all shrink after I ate leaving me cold. Fat reaction or something. But it went away in time, and now I feel normal or even get warm instead of getting cold after eating.
Steak, eggs, potatoes - fruits, nuts, berries and forage. Coconut milk and potent herbs and spices. Tea instead of coffee now and teeny amounts of kelp daily. Let's see how this does! Not really had dairy much, and gut seems better for it.
I almost always get cold after I eat. I always figured it was the digestive process where the body directed blood away from the limbs to help with digestion. Drinking something warm can help. Right now I'm still recovering from a wicked respiratory infection where I was spiking 100+ fevers and I'm having issues with the cold weather, which has been below normal for the month here.
