I am severely overweight but been doing slimming world since January to improve our chances of having a baby. Got pregnanct in March but unfortunately lost baby in May so I quit and put on 10&1/2lb. Now been back 6weeks and  lost another 1st13lb so 1lb of 2stone, which means in total I've lost 4 stone. Starting to have regular ovulation and getting EWCM which I never had before so defiantly think me loosing weight is improving our chances of having a baby. Even though I've got a hell of a long way to go before I'm at an ideal weight I feel so much healthier and happier with my weight
