I'm 17, 5'2'' and hovering around 132-135 lbs. I want to be around 120-125. Is that a good goal?
Also, my breasts are about a 34c. Will losing this weight shrink them a bit?
Answer on Weight loss question?
125 is a very sensible goal and also a healthy, safe weight.
Hard to say if your breasts will shrink or not. If you are lucky, you may burn fat from problem areas (legs, bum, arms, tum) and not breasts, but as breasts are also fat, there is no guarantee that they won't shrink.
Personally, I think they will shrink, but I wouldn't have thought they would drop by a cup size, you're losing under 10lbs so you shouldn't notice much of a difference, even if they do shrink a little.
