Why did my ex gain so much weight?

I'm not being snide or rude, but he used to be heavy into body building a few years ago and was ripped. We weren't together long at all, but in his latest photo I saw he had gained a good 30 lbs from the last time I saw a photo of him. He's still handsome in my eyes. We broke up because he wasn't willing to meet my needs and he blocked me at the time. I've actually lost 25 lbs. Because I'm still hurt over it all and I'm trying to make it so I'm actually worth something to someone next time. I think he's with someone new but I don't know how you can have so much pride in yourself flexing and all to that (even had old memes of him joking about people) to where he is now Even when I was with him there was barely any light in his eyes. I don't find it funny I'm worried.
