Trim the Sides: Expert Tips on How to Get Rid of Side Boob Fat

Do you struggle with excess side boob fat? You may have to adjust your sports bra over your side fat every time you dress to hit the gym. These struggles can be frustrating for those seeking a leaner appearance.

While side boob fat is an unsightly concern for many, it is totally preventable. You can easily banish this side fat by following a calorie-deficit diet and working out.

If you wish to overcome this, you have landed at the right place. This article covers how to get rid of side boob fat and the various exercises to get a slimmer appearance in no time.

How To Remove Breast Side Fat and Underarm Fat?

Side boob fat, or underarm fat, is the excess fat that gathers under your armpits and the side of your breast due to excess weight. In other terms, fat is stored under the armpit and in some cases, may be a condition called the axillary breast (10).

Excess fat accumulates in different areas of the woman’s body, which may also affect their self-esteem. Women also tend to store more fat than men naturally. The good news is that side boob fat is preventable and can be reduced by following a particular fitness regimen.

One important thing to note is that you cannot do spot exercises or target the side boob area specifically to lose fat. It would help to incorporate a full-body workout to reap the results and lose excess fat.

Lean and toned up body isn’t just a far-fetched fantasy. Check out the BetterMe app and watch it propel your weight loss journey into high gear!

Here is how you can get rid of side breast fat.

Restrict Your Caloric Intake

The diet you follow has a huge impact on your appearance. If you consume sugary and processed foods regularly, your body may store more fat, which ultimately can contribute to side-boob fat. The first step is to reduce caloric intake and shift your body to the fat-burning phase. 

To do that, you need to burn more calories than you consume. For example, if your daily recommended calorie intake is around 1300 calories, you need to stay behind that number and not exceed the limit in order to lose weight. You can create a calorie deficit by either exercising or consuming less food (7).

However,  this doesn’t mean you can skip your meals, as that could lead to a  nutrient deficiency and may lead you to experience fatigue, nausea, and tiredness. The following are some tips that will help you improve your eating habits:

  • Avoid eating before going to bed. Make a habit of eating at least 3-4 hours before bed.
  • Follow a portion control strategy and consume smaller meals instead of three big meals throughout the day.
  • Prepare your meals in advance and bring them with you.
  • Consume more protein (at least 0.8 g per 1 pound of body weight) as an adequate protein intake helps build muscle and lose body fat (1). Also, protein has a higher thermic effect than carbs, revving your metabolism and helping you lose weight even when not exercising.
  • Replace sugary foods with natural fruits.
  • Avoid junk food, alcohol, and similar beverages.

Tweak Your Diet

In addition to reducing your calorie intake, it is essential to tweak your diet. You can follow the keto diet, a popular weight loss program designed to shed weight rapidly. A keto diet comprises foods low in carbs, moderate in protein, and high in fat (9).

While adding more fat to your diet to lose weight seems counterintuitive, it ultimately comes down to a calorie deficit. When you completely reduce carbs, you will lose weight rapidly as the body uses up stored carbohydrates and water, and enters the ketosis phase, which converts fats into ketones (9).

Following a keto diet can be one method for some individuals, however, it may not support optimal health in the longer term and can be difficult to maintain. If in a true ketosis phase, your body can burn fats and use them for energy. In addition, you can also do intermittent fasting by following a 16-hour fast, as this helps you prevent overeating and regulate your weight.

Exercise Daily

Along with your diet, incorporating a combination of strength training and cardio regularly can be an effective approach to achieving results. Exercises like deadlifts, bicep curls, and barbell presses can help tone your chest and arms effectively, whereas bodyweight exercises and cardio help you shed overall fat. By exercising regularly, you may also develop firmer and perkier breasts.

Get the Right Bra

The bra you wear can have a significant impact on how your breasts appear. About 8 out of 10 women wear the wrong bra size and suffer from such issues (2). Wearing the wrong bra makes your side boob fat more visible and gives an unsightly appearance.

To counter this, you need to get a bra that provides comfort and adjusts perfectly with your bust. You can counter this problem by consulting the bra size chart and doing the necessary measurements.

Here’s how you can find out your perfect bra size:

  • When you try the new bra, check that the front and back sides are even.
  • After wearing the bra, raise your arms above your head. If your bra slides up your boobs, it means your bra is too big. Ideally, the bra must not ride up. Its band should be parallel to the floor.
  • The bra band must not feel too tight around our chest. It must feel tight, but not so much that you can’t pass your finger through it.
  • The bra must adequately hold and cover your breasts and not cause your boob to spring out. Also, it must not let your side boobs roll out.

Breast Reduction Surgery

Breast surgery or lateral breast reduction is the last resort when you have tried working out and adjusting your diet. It is a safe cosmetic surgical procedure where the surgeon removes excess side fat from your side boobs and armpit area (4).

Since it has no potential side effects, the surgery has become quite popular among women. After surgery, you will witness perkier, fuller, and more firm boobs.

Get More Sleep

Women, especially young mothers, often get a few hours of sleep due to attending to their babies all night. A study shows an association between sleep time and weight gain (3). Sleeping less than 6 hours daily was associated with more weight gained in comparison to those who had adequate sleep levels.

The ideal sleep time for healthy adults is 7-8 hours daily (3). You may need to reevaluate your sleep schedule if you have excess fat.

Manage your Stress

Lastly, being under stress makes us stress-eating and consuming high-calorie foods. Managing your stress levels by methods such as meditating and yoga is important, as high stress levels may lead to weight gain (6).

What Causes Side Boob Fat?

Side boob fat is something we all wish to eliminate. While excess body fat seems to be the probable reason behind the distributed fat, several factors, such as age, genetics, and diet, can play a crucial role. Let’s look at the major side breast fat causes to learn more about this fat accumulation:

Genetics play a huge role in how much fat our bodies store. Some people are more inclined to store fat naturally than others. If you have side boob fat, chances are you inherited it from your maternal or paternal side. This is because our genes influence breast shape and size (7).


Aging may impact the breasts as we age. With time, muscles holding our breasts wear out, making our boobs sag and become loose. This also causes our skin to lose elasticity and become saggy, leading to a side-boob appearance.


Breasts change a lot during pregnancy, swelling and enlarging in shape. Sometimes, the skin may not restore and become firm like it was once before giving birth, leading to side boob enlargement.


Most importantly, our diet plays a huge role in our body fat. Eating a sugary, processed, and high-calorie diet can lead to weight gain, which ultimately results in excess body fat.
