Trying to lose weight

I am currently going through my 2nd miscarriage in 1.5 years. I had another last year.

So I've decided to use this time to lose some weight and get healthy for my next try and hope itll help.

Yes im obese, I'm 5 ft 3 and 295 lbs.

While we wait for my body to get ready to try again I want to start exercising and eating right.

Can anyone tell me where to start, give me some tips? Anything helps. Im very busy I work a lot and only have a little time in the evening for exercise so even if someone has recommendations on home exercising that would help too.

Also tips on meal preps what to eat. What not to eat. Etc
