Weight loss suggestions

I’ve been trying to get pregnant for about 5 years now, with no luck. I’m not yet to the point that I want to seek medical help - id like to get pregnant organically. With that being said, I think my weight is a big issue with my fertility so I need to start losing weight.

I’m 5’5 and around 240 pounds.

Ideally, I’d like to be around 180-190 pounds.

I love food and sweets so much and find diets extremely difficult.

Looking for recommendations on how to lose weight successfully and keep it off.

Advice?
