Is it possible I could go from a 34 DD to a C with regular exercise?

There are two ways to reduce breast size that may work. First, if overweight a woman can lose weight and breasts may get smaller. But, by your numbers you are not overweight: Your BMI is about 23, which is within normal range.

Second, if someone is "flabby" with a high body fat percentage exercise--especially weight training--can build muscle and burn fat, potentially reducing the size of a woman's breasts. It's not possible to answer if that might apply to you.

It might be helpful for your mother to actually see your breasts (if she hasn't already) and to have her join you in a consultation with a board certified plastic surgeon to get a professional opinion. Your mother may believe you are too young to make this sort of a decision. Best of luck! Dr. Jim Romanelli

Thanks for your question. There is no doubt that diet change - ( intermittent fasting or a keto diet) will get you down from a DD to C. the only issue may be sagging of the breast as you lose weight. Losing weight slowly will help reduce the amount of dropping but not a definite. A breast lift could be considered in the future if you don't like the amount of droop that you might get after weight loss.

Some women find that when they lose or gain weight that their breast size changes. If that is true for you, losing weight in a healthy way may decrease your breast size. There are no specific exercises that will increase or decrease breast size. If you are interested in a reduction, see a board certified plastic surgeon for a consultation.
