Is it in my best interest to go out with a few men who have asked me, even though I don't look that great right now?

I’ve gained a little weight, out of shape… I’m just wondering if I should put them off a few weeks, or just meet them and hope my winning personality is enough :) Maybe just fake feeling attractive for a while. I kind of feel like a bird in the hand… on the other hand, I’m more successful dating when I’m confident.
