I used to have real appetite problems. It's tough to eat when you're not hungry. It got better on SCD, and I've finally gained some much needed weight. The only problem is that I crave carbs way more then anything, which I prefer to limit (carbs feed too many nasties in the gut). Meat doesn't excite me much, but I eat it just because my body needs it. But what I really want is to chow down on nut butter and honey *drool*.
One thing that sure boosted my appetite was Zyrtec. I started taking it in the summer, and became an eating machine. When I looked it up, I found that increased appetite is a rare side effect. I call it prednisone-lite
