Help please! (Weight loss)

I was recently told by my doctor that I was misdiagnosed and I do not have PCOS. She did tell me that to possibly get my irregular periods back on track to start losing weight.

Now I have never thought I would be able to conceive because of being a lesbian with pcos. Now it seems more possible and I’m pushing myself to make my dreams happen. I’m posting to ask for what others have done to lose weight. I know that what works for one does not work for all but I’m unsure where to start. 😁
