Struggling Pcos food choices

So my doctor told me cut back alot on food like bread and sweets. I am hard time finding alternatives I like. I love ice cream . I love biscuts. My wife says not paying for a specialist unless necessary. She says loves me and knows I can mske changes needed. I just really want something in place that Doesn't taste like diet food. We are supposed start ttcing in January so far my periods are out whack. I feel bad but eatibg always been my go to thing.
