Will The Keto Diet Reduce Your Breast Size?

Women who begin a ketogenic diet often wonder whether this way of eating will reduce their breast size. Some hope that they’ll stay just as they are, while others hope to get some back relief by shrinking them.

Will the keto diet reduce your breast size? When losing weight with keto, there’s a good chance that your breasts may get smaller. This is thanks to the fact that you can’t choose where your fat loss comes from.

Are you concerned about what following a keto diet and losing fat will do to your chest? Keep reading for some information that you’re going to want to know!

Will Your Breasts Get Smaller on Keto?

For the most part, gaining or losing weight doesn’t play all that much of a factor when it comes to your cup size, but this can vary from person to person. One woman may be able to lose 20 pounds and see their breast reduce by a cup size while another woman may not see any change until she loses 40 or 50 pounds.

There’s no way to tell for sure what’s going to happen to yours, but there isn’t a single person in this world who knows her body better than you! Think about when you’ve lost or gained weight in the past. Were your breasts the first place affected, or did it take some time before you noticed a difference?

Every person’s body is different, and nobody loses weight the same way. While one person may see a quick weight loss in their breasts, another may only see it in their stomach, while yet another loses weight in their thighs first. There’s no way to tell what’s going to happen until you lose the weight. It’s also important to note the everyone’s breast tissue composition is different as well.

Your breasts are made up of a layer of fat with varying levels of thickness. If your breasts are more dense with tissues, you probably aren’t going to lose much weight in the area. On the other hand, if they are more fatty, it’s only natural that they’ll begin to shrink as you burn the fat from your body. For the most part, large breasts will remain large and small ones will remain small.

Keto And The Shape Of Your Breasts

You might want to sit down for this. I apologize in advance for any sadness this causes, but typically, weight loss will lead to your breasts sagging. To give you an idea of what this may look like, I’m going to use a balloon as an analogy.

Think about a balloon that you’ve blown air into. It’s nice and tight. When you let out some of the air, it’s still pretty firm, but not as firm as it was when it was full. Now, what happens when you let all the air out? Instead of returning to its original shape, it is not stretched and saggy. No matter what you do, it’ll never be like it was in the beginning.

Your breasts are just like balloons when it comes to gaining and losing weight. When your weight increases, it’s the same thing as a balloon being inflated. When your weight decreases, it’s the same as a balloon deflating. Every time this happens, the skin that surrounds your breast tissue loses more and more elasticity, making it harder to contract around the shape of your chest.

How Bad Will The Impact Be?

Not every type of weight loss is going to have the same effect on your breasts. People who lose weight rapidly often have the biggest problem with their breasts sagging. This occurs because your skin cannot keep up with how fast your chest is shrinking, thus disrupting the amount of collagen that your body can make.

Unfortunately, losing weight too fast will lead to breasts that have stretch marks and a deflated look. They’ll probably be fuller on the bottom, while much emptier on top with your nipples pointing downward instead of straight ahead.

What Can You Do To Minimize The Damage?

The first thing you should do is throw the idea of a starvation diet out the window. The fact that you’re researching keto is a good start, but too many people try to combine severe calorie restriction with keto, and the diet wasn’t designed to work that way.

Just like the rest of the body, your skin needs proper nutrition. If you are starving yourself and not getting enough calories, you will make matters worse for yourself.

The same can be said about losing and gaining weight over and over, also known as yo-yo dieting. The integrity of your skin gets weaker every time you gain and lose the same weight. I know it’s easier said than done, but if you’re able to stick to the diet, you’ll already be far ahead of the curve.

The best way to prevent too much damage to the skin around your breasts is to lose weight slowly and steadily. Yes, keto is known for an initial weight loss that’s larger than most diets, but that’s only because of water weight. Once you become keto-adapted, a slow and steady weight loss of one to two pounds each week is normal. Losing weight in this manner gives your skin the most significant opportunity to adapt to the changes of your body.

What Can Be Done?

As a woman, it’s natural to feel, for the lack of a better word, deflated over the thought of your breasts losing their natural shape. It is not the end of the world, and there are a ton of things to do to give yourself a lift!

The first thing you should consider is changing the bra you wear. A bra that has some padding on the lower side helps to give your breasts a fuller look on top. Here are some of your best options.

T-Shirt bras are sleek and seamless. They offer a ton of lift and support. A t-shirt bra has molded cups that smooth the breasts’ appearance, making them look round and lifted. These bras work great when you’re wearing tight-fitting clothing.

Recommendation: Hanes Ultimate T-Shirt Bra

If you have larger breasts, your best weapon against sagging will be a full cup bra. This type of bra gives you the full coverage you’re looking for while providing support and eliminating the top and side spillage. The molded cup will provide you with a gentle lift as well.

Recommendation: Vanity Fair Beauty Back Smoothing Bra

An underwire bra will be your best option when you’re looking for support to lift sagging breasts. If you want a bra with no padding and is comfortable and lightweight, this should be your choice. It’s perfect when you want the most natural shape possible.

Recommendation: Warner’s Full Coverage Underwire Bra

Last, but certainly not least, we have the ever-popular push-up bra. If you’re fighting a losing battle with gravity, these bras will give you the extra lift you need. These go great with tops and dresses with a deep neckline. The bra supports your breasts, keeping them close together for the best look possible.

Recommendation: Deyllo Push Up Comfort Bra

When you’re looking to purchase new bras after weight loss, it’s essential to make sure you have the correct fit. A bra that fits the way it’s supposed to helps give you a slimmer appearance. If it’s been a while since you’ve gone bra shopping and you’ve lost weight, it isn’t a bad idea to re-measure and check out some new styles you can try on.

Alternative Options

If you’ve tried new bras and they aren’t quite working for you, you do have some other options available to you. Since the collagen and elastin in your skin have broken down, you can make your breasts appear perkier using a product that encourages the production of these two proteins, such as a retinol-based body cream.

If that isn’t quite what you’re looking for, some doctors experiment with treatments using radio frequency and ultrasound. If you choose to go with one of these options, it’ll be important to set your expectations low. Doctors agree that the results are going to be subtle at best.

Finally, you do have surgical options available to you. Many women choose to get a breast lift when they reach their weight loss goals as a reward for their hard work. Many surgeons have a simulator that can show you precisely what you’d look like with implants, a lift, or even both. Contact one in your area if you’re curious about going down this route.
