Losing weight

Michelle🐶 • 8 angel babies, now divorced but still hopeful for my first human child - already have my pitbull fur baby!!
While TTC and during pregnancy (hopefully). What is the best/healthiest way to lose fat while TTC and then leading into pregnancy to keep hormones even and baby safe? I have like 60 lbs to lose and I want to start now and continue during pregnancy. I know I cannot lose all if pregnant but I need to get healthier due to pre diabetes
