I was doing Paleo and the sweating got better, went back to "normal" food, it came back. It's similar to what VillageGirl describes above, lots of fruits and vegetables, sweet potatoes, no sugar, grains or legumes. Mostly fresh, whole foods as unprocessed as possible. It really wasn't that hard to do but I thought thought I would take a break, but it's not worth it, the sweets don't even taste good to me anymore, and the sweating is ridiculous. I have to take a shower just because I mopped the floor.
Old age is not for sissies.
