Has anyone had any luck getting pregnant on the keto diet?

My partner and I are on cycle 11, both heavier than we should be. Our doctor is sending us onto a specialist and I’ve contacted the clinic and they’ve said that they would ideally like me to have a bmi of 35 before starting anything, which means I need to lose 13kg to get there

I’ve lost 20kg in the past on it and since stayed the same weight, however I was wondering if anyone has had better luck whilst on the keto diet for TTC
