Generally, no. But I wouldn't rule someone out right off the bat just for being overweight. There are a couple of lifestyle health habits i need to really take more seriously. But I visit the doctor, dentist, et al regularly, and my diet is meticulously healthy. At our age, a good number of people do not even do their annual physicals like they should. The few that I have dated who are like that, I took on more work than a person should, to try to get them just to get up to date on their stuff. If they wanted to eat like me, I had to prepare their meals. Like, its just too much. It just depends on someone's effort and their outlook. On the flip side, I dated a guy for a while who was a regular gym goer and I am not. It would have been cool if I could've shared some of my plant based diet with him, and he could've shared the gym with me, as sort of ambassadors, and supportive of each other's health endeavors. But he liked sabotaging the way I eat by tempting me with restaurants where I would likely cheat, or not have much plant based options. I asked him to introduce me to the gym and he kinda blew the idea off. People can tear you down or undermine you without being conscious of it. So just meeting somebody who has a "healthy lifestyle" doesn't mean you'd be good partners in health, either. In any case I guess a person just has to try to guage the others' genuine willingness to not only do for themselves, but to respect and share back and forth with you, to compliment each others healthy habit strengths and both become even better.
