After a breast lift with implants surgery, if I were to lose weight would that cause my boobs to sag again ?

Losing too much weight in a short period of time may cause skin to be saggy. You should consider losing 2-3kgs/month not more to reduce the risk of sagging after surgery. Another way to prevent sagging is to lose weight than get your surgery done.

It's the stretching of the breast tissue with at least 10% up and down weight change that could be the culprit in some cases. Dr. Ted Eisenberg, Board Certified Plastic Surgeon and Author. RealSelf Distinguished Hall of Fame Inductee. Philadelphia, Pa., USA
