Devices such as breast enhancement pumps use pressure and suction to pull on the breasts. This causes them to stretch and swell, which may make them appear larger, temporarily.

Breast enhancement pumps range from just a few dollars to several thousand. Some are even classified by the FDA as 510(k) class II medical devices. Despite this, there are no clinical trials indicating that any device, whether inexpensive or very expensive, will enlarge breasts.

The size of your breasts is largely determined by genetics. When women think about breast size, they often focus on breast volume or fullness. Other factors, such as chest circumference, also play a role in how large your breasts appear.

Both breast volume and bone structure are physical characteristics that can run in families.

Breast size changes with weight and age

In addition to heredity, other factors go into determining breast size. These include weight and age:

• The way your breasts look when you’re a teenager is bound to be different than the way they’ll look later in life. Their size may increase or decrease, and some sagging is likely to occur.
• Cup size and torso circumference can change significantly with weight gain or weight loss. If you lose or gain 20 pounds or more, your bra size is likely to go up or down.

Hormones and reproductive cycles affect breast size

Hormones, and the reproductive cycle, also affect breast size:

• Breast tissue starts to plump up with fat during puberty, when your ovaries start to produce estrogen.
• Your breasts may temporarily get bigger right before your period, when estrogen and progesterone enlarge the breast ducts and milk glands.
• Enlarged breasts are one of the first signs of pregnancy. Estrogen, progesterone, and prolactin work together to stimulate breast enlargement and milk production. Your breasts will continue to increase in size throughout pregnancy as they prepare for lactation.
• During menopause, a reduction in estrogen may cause your breasts to lose elasticity and shrink in size.

No food or diet plan has been clinically proven to increase breast size.

There are also no supplements, pumps, or creams that can make breasts larger.

The best natural way to enhance the look of your breasts is to do exercises that strengthen the chest, back, and shoulder area. Good posture also helps.

Possible to Increase Breast Size with Diet? Options That Work

If you’re looking to naturally increase breast size, don’t look to your refrigerator. No foods or eating plans have been clinically shown to enlarge the bust.

Gaining weight may, however, increase the size of your breasts and the rest of your body. If that’s not the result you’re looking for, there are options other than diet that may help your breasts appear larger.

Keep reading to learn more about breast-growing options that work. We’ll also take a look at some options that don’t work for breast enlargement.

Try chest development exercises

Exercise won’t make breasts fuller. However, the right exercises can be very effective for developing the pectoral muscles underneath your breasts, as well as your back and shoulder muscles. This can help your breasts appear larger, higher, and firmer.

Some exercises to try include:

• wall presses
• pushups
• chest press extensions
• Cobra Pose

Work on your posture

There’s no downside to having excellent posture. While good posture won’t physically make your breasts larger, it can enhance their appearance by making them look perkier.

Good posture also supports balance, strength, and flexibility. It also helps strengthen the stomach and back muscles.

Exercises that help improve posture include:

• Child’s Pose
• plank exercise
• Cat-Cow Pose

Consider a new bra

Many women are wearing the wrong bra size. In fact, there’s research indicating that 70 percent of women wear bras that are too small, and 10 percent wear bras that are too large.

A too-tight bra may flatten breasts, making them appear smaller. It can also cause unflattering spillage over the sides and back.

A too-large bra won’t support breasts, making them look saggy.

It’s also detrimental to wear a bra that’s too old. Bras stretch in the wash, and after many washes, they may no longer fit according to the size on the label.

Your go-to bra may need to be replaced with one that fits correctly. A well-fitting bra can promote and accentuate your breasts, making them look their best, no matter their size. Consider getting professionally fitted the next time you go bra shopping.

Eating certain foods

A quick internet search is bound to yield a ton of articles touting the ability of certain foods to increase breast size. Unfortunately, none of these claims are backed by clinical evidence or legitimate science.

That includes dairy

Whether it comes from cows, goats, or other mammals, all dairy milk contains estrogen, progesterone, and prolactin. Since hormones affect breast size in humans, some people are under the impression that drinking lots of dairy milk is a good way to enlarge breasts.

This is a falsehood. Drinking milk and eating dairy products won’t increase breast size.

According to a 2019 study, dairy milk may affect breast cancer risk. Most dairy cows are pregnant, so their milk contains higher amounts of hormones. These hormones may raise levels of insulin-like growth factor 1, a growth hormone.

Some studies show a modest association between higher levels of insulin-like growth factor 1 and breast, prostate, colorectal, and ovarian cancer. While these findings aren’t conclusive, you may wish to limit your intake of dairy milk if you’re concerned or have other risk factors for cancer.

However, other studies suggest there’s no increased risk for breast cancer if you consume dairy. If you do have a family history of breast cancer, it’s best to speak with your doctor to address any concerns.

Soy-based products won’t increase breast size either

If you’re swapping out dairy for soy in the hopes that it’ll increase breast size, don’t bother.

Soy milk and other soy-based products contain phytoestrogens. These are plant-based compounds that mimic estrogen’s effects on the body. For that reason, some people think that soy will help their breasts get bigger.

As is the case with dairy milk, this is a falsehood. There are no clinical studies, and no evidence, linking phytoestrogens to increased breast size.

Natural breast enhancement products

Many products on the internet promise to increase breast size. These include lotions, creams, massages, and supplements. They also include devices, such as enlargement pumps. There’s no clinical evidence indicating that any of these products or devices have any benefit at all for breast size.

Breast enlargement supplements

In addition to being useless for breast enlargement, supplements may also be unsafe. Be wary of so-called breast enhancing supplements, as they contain herbs and ingredients that might cause serious interactions with medications you’re currently taking. They also have no proven health benefits.

Breast enlargement creams

Some breast enhancement or enlargement creams may be beneficial for the skin, but they’ll do nothing to increase breast size. There are no studies indicating that any cream, lotion, or topical treatment can enlarge breasts.

Some creams indicate on their label that they have approval from the Food and Drug Administration (FDA). This may be false advertising, so be sure to research the cream before you buy it.

Breast enlargement massages

Breast massage is great for stimulating blood flow, supporting lactation comfort, and detecting potentially malignant lumps. However, it’s completely useless for getting bigger breasts. There’s no scientific data that breast enlargement is possible through self- or professional massage.
