I'm always stunned at how folks are "below" the BMI for their height!! I'm above it ... but I'm at a healthy body size ... or within 7lbs of a healthy body size.
5' 7" and 171lbs ... on my way down to 165lbs. (bmi tells me my perfect weight is 154 ... but that is simply too thin for my frame). I think 158 to 162 would be ideal for me. But, being able to stay at that weight compared to 165 to 168 is SO tough for me.
