I have been running for a while now and dieting, and I've lost a couple of pounds of weight. I'm now 130 lbs and 5 foot 11, and 25 years old. As a result, my breast size has also decreased.
I've heard that you lose more of your breast fat if you're on a calorie deficit, than what you gain if you're on a calorie surplus.
In other words, I've heard that if you lose 5 pounds, and then gain 5 pounds, you will have relatively less fat in your breasts in the end than before you lost the 5 pounds, and relatively more in your belly.
Is this true? is there scientific evidence for this, or for it being false?
