I used to consume very little salt and drink tons of water (even when I wasn't thirsty), and eat lots of low fat "health products" because that's what the "experts" recommend. I always had salt and food cravings, very low body temperatures (couldn't even be in an air conditioned room in the dead of summer),while developing a gut.
Now I just try to eat whole foods and trust what my body tells me and I feel tons better. Body is warmer and gut and food cravings disappearing. I've learned to trust my instincts more than the "experts."
