Should I give the girls a chance that rejected me for being overweight in the past?

I use to be overweight and there were girls that rejected me due to being overweight which there's nothing wrong with that. So i started working out & improved my weight & physique. At some point i ran into the girls that rejected me because these girls i met at my college & they started treating me differently and were more nice & wanted to have conversations with me. 4 out of the 6 that rejected me in the past were interested and wanted to date me. But i remember the past and i can't let that go. In the past they didn't even want to talk to me as friends & made up excuses to stop talking to me. But now all of a sudden the interests is there and they're acting really nice. I don't know if i want to date any of them because they just seem fake as fuck acting like that. They're very pretty but still that's not enough for me to just forget about the past. What should i do?
