HELP, PLEASE.....Losing weight with PCOS

Has anyone or is anyone losing weight witv PCOS? If so what is your diet, what is it that you are doing, or did? I am just lost and confused on what to do anymore. I have heard keto works wonders. How does one get started? What is the best routine, Morning workouts or evening workouts? I have twin 2 year olds and I watch my 5 month old nephew Monday - Friday. I also have a husband who drinks about 3-4 days a week and is not very helpful with this process. I am currently 32 years old 5'0 and weight in at 260 pounds.

I lost 80 pounds before I found out I was pregnant, but it was a very unhealthy way.... I just need help and I am looking for insite with this process.......
