22.5 now. 6 years back I was 27.3, went on a program and lost 40 lbs over 6 months. So far have managed to keep most of it off. The thing I noticed immediately was the improvement in blood work from the annual physicals (cholestrol and Tryglycerides in particular), plus BP came down quickly to normal. (it was a marginal BP reading that finally trigered by action to lose weight and exercise).
