My Coworkers turned on me

Ever since I've changed my diet, been on semen retention, started going hard in the gym, I've been isolated by my coworkers. I don't brag or gloat, I just keep to myself and work. When I was overweight I was treated with love and kindness. Now I'm treated harshly, and I also attract more attention. Nobody cares when your fat and you don't say " Good Morning" but when your in shape it's a direct insult. It's crazy how you only become visible when you change yourself for the good. Has anyone else experienced this? Please no gas lighters
