Yep, it has done it for me. I am trying to have snacks and things on top of regular meals now. Included some desserts now and again to prompt some extra eating. Have been as low as 95lbs and now 97, have never been this low my entire adult life. I am also 5'2". People are telling me I am too thin now, asking if I am well. I haven't been doing running either. I really need to get more muscle and get serious about working out. I am eating lots of meat, fruit, veg, and fat everyday. So you sound similar to me really.
