I was recently on a date with a very cute, very fit woman who just ran her first marathon. In my profile I very clearly state that you need to have a healthy bmi for things to work between us and that's actually what made her want to connect. Pretty funny because she's very supportive of woman but after one trip out of the country with an overweight friend who could only survive a tenth of the walking/exploring she wanted to do, she saw the importance of a physically healthy partner.
