Is It Bad to Loose Weight Before Breast Augmentation?

The answer to your question really depends on how weight loss affects your breast tissue as well as how much weight loss you are asking about.  Some women gain and lose breast tissue whenever their weight changes.  They will see the same situation after breast augmentation, so if they have their implants placed when they are at a heavier weight, their breast size will diminish when they lose weight.  Other women do not tend to have much change in breast size when they gain or lose 10 to 15 lbs.  These women will likely not have much change in their breast size after augmentation when their weight changes.  For weight loss in excess of these amounts, some breast volume loss will probably occur.

I agree.  It is alway better to be at your stable comfortable  weight. If you loose a lot of weight after augmentation you may see more drooping of the breast and it may affect your final size goals.  Most of my patients embark upon surgery when thay are about 10 pounds from their goal.  Most people live about +/- 10 pound from ideal.
