How Much Weight Should You Lose After Breast Augmentation Before It Affects the Appearance

Here is what happens to your breast size when you change weight after having breast implants*:


Breast Implants + Weight Gain = SMALLER Breast Size



Breast Implants + Lose Weight = BIGGER Breast Size


*Proportional to your body

This may seem counter-intuitive, however remember that this is what happens proportionally. Here is how this works:

When you gain weight, the added pounds disperse throughout the body, not just in the breast. When you gain weight with breast implants in place, the portion of your breast that is your own breast tissue does increase in size, but the portion of the breast that is breast implant stays exactly the same. Therefore, even though your total breast volume does increase, it does not increase as much as the rest of your body proportionally. As a result your breast appearance will often seem smaller in proportion to what it was before the weight gain since you are increasing in size throughout the body.

When you lose weight the reverse happens. You will lose weight throughout the body, not just in the breast. Your actual breast tissue will decrease and the implant size will stay the same. However, since your body overall is decreasing in size your breasts will appear bigger in proportion to the rest of your body. In my practice in Denver, I've seen seen several patients over the years that have requested smaller breast implants for this very reason after weight loss, and some of these patients required a breast lift.

Note that a few pounds of weight gain or loss will typically not be noticeable, and what actually happens when your weight changes varies a good bit from patient to patient and depends on the breast implant volume vs actual breast volume. Some people have higher proportion of fat vs. glandular breast tissue in the breast. This can effect the possibility of sagging with weight loss.

To answer your specific question, you may have some sagging of the breast after gaining and losing about 10% of your body weight, depending on your tissues (which will vary a lot person-to-person). From your weight, I'm guessing that your implant size has stretched your skin envelope a good deal (which is the price your tissues pay for a very large implant), but since you are keeping the implant in place, it may not cause a problem.

How weight loss affects patients who have undergone breast
augmentation varies from patient to patient.Obviously, when patients have massive weight loss, the breast can be
impacted significantly.This may result
in noticeable loss of volume with associated breast sag.In the
vast majority of patients whose weight fluctuates within a normal range, breast
changes are usually minimal.Each
patient’s response to weight loss is different.In some patients, the impact can be dramatic while, in others, it may be
barely noticeable. In
short, there’s no way to accurately predict how weight loss will impact any
individual patients breasts.The best
indicator is probably how the breasts have responded to weight loss in the
past.

Since everyones body is different, it is hard to tell you how much weight you can lose before your breasts will change in appearance.  It also depends on how much fatty breast tissue you have. 

You dont say if your implants are in front vs behind the muscle, how large your breasts were before your surgery, or if you had any drooping before or after surgery.  Breast tissue is made up of both parenchyma (breast tissue) as well as fat.  Some womens breasts will change dramatically with weight gain or loss, some womens breasts change very little.  If you had the surgery at your current weight, then it is likely that you did not have much breast tissue to begin with, thus your breasts should change very little.  But this is just a guess.  There is no specific way to loose weight that will preserve the way that your breasts look. Good luck!

The effect of weight loss after breast augmentation is highly variable. Most of the time, weight loss does not affect the appearance of the breasts after having breast implants. Typically, you will notice the weight loss in your body to a greater degree than in your breast.
