Despite being part of a culture that is obsessed with boobs, we don't know too much about them. There are tons of boob theories floating around about size, shape, what's normal and what's not. But are any of them actually true? Here are the top 11 biggest myths you've been told about boobs, and why they are definitely false.
Gaining Weight Means Getting Bigger Boobs

Before you start eating all those candy bars, know that gaining weight will not necessarily make your boobs bigger. Everyone distributes fat differently on their body. You may gain weight in your boobs, but you also could gain weight in your butt, legs, stomach or face.
Losing Weight Means Getting Smaller Boobs

This is not necessarily true either. People have different percentages of breast tissue vs. fat in their breasts, making some more dense than others. So, while some people may see some shrinkage when they lose weight, others may not.
Wearing A Bra To Bed Keeps Your Boobs From Sagging

Even though it seems like it would make sense to wear a bra to bed because of gravity, it's actually worse for your breasts. It's uncomfortable and your boobs need a break after a long day of being trapped. Plus, researchers don't really know why boobs sag so this can't be proven.
Your Boobs Stop Growing After Puberty

While your boobs begin growing during puberty, they can continue to grow well into your 20s and their size fluctuates! Pregnancy makes your boobs grow and many other factors can contribute to their changes.
Having Lots Of Sex Will Make Your Boobs Bigger

Unfortunately, there is no scientific evidence of this. It may make sense in your mind that sex means hormones, which means bigger boobs, but this boob fact is definitely just a myth.
Certain Foods Make Your Boobs Bigger

Things like soy milk, squash, carrots, nuts and garlic have been thought to have breast increasing qualities. While these foods may have other health benefits, no studies have proven that they benefit your boobs.
Your Boobs Will Be Your Mom’s Size

This one may ring more true than others. There are definitely some genetic components to breast size, but other factors affect size as well. So fear not, you may not look exactly like your mother.
Sleeping On Your Side Can Cause Uneven Breasts

While many people have one boob that is bigger than the other, this is not caused by sleeping on their side. Feel free to sleep any way you'd like, because you don't have much control over the uniformity of your boobs.
Wearing Bras Causes Breast Cancer

Only one study on the link between breast cancer and bras has been conducted, causing this myth to circulate. The study did not even have conclusive findings, so you have nothing to worry about.
Guys Only Like Big Boobs

Some guys may have preferences for big or small boobs, which is only natural. But most do not discriminate. Boobs are boobs, and they'll always be fascinating to any man lucky enough to see them.
Some Breast and Nipple Shapes Are Abnormal

Unless you have noticed some significant changes in your breasts besides size, you have nothing to worry about. Boobs of all shapes, sizes, and colors are normal, and each person is unique in their own way. Quit comparing yourself to what you see around you and love your boobs for what they are!
