By dry lot, I am assuming you mean lack of pasture. That is pretty much standard here, so there is no need to refer to it as a dry lot. Just pen, paddock, or field. Heck, I even call our 2 acre pen our pasture (with no grass). :)
Anyway, there must be something else going on with your guy, because our horses survive well without pasture. I try to be very liberal with the hay, and depending on hay quality, I give no grain to 4lbs of complete a day. We had some really leafy round bales last year. All of our horse got fat on that with no grain at all. This year, our hay is different, and I have been supplementing nutrients in the form of Nutrena safe choice - about 1lb 2x a day to the older gelding, up to about 4lbs a day to our preggo mare. My preference it to give hay free choice - bet again, that depends on who I am getting it from, and the quality of hay.
For you, I would say a health check is in order...it seems that your guy should have picked up weight.
