What Causes a Double Chin?

A double chin is not really a second chin; it’s a layer of fat, called submental fat, that develops under the chin and gives the appearance of two chins. Why do we have double chins? Most people assume they are a result of diet and weight, but that’s not necessarily true. There are other double chin causes, such as age, genetic makeup, and posture. Different factors play into double chin development. Let’s explore what those are and possible ways to get rid of this unwanted fat.

Diet and Weight

If you are gaining weight, you might start to see a double chin develop. If this is the case, you might be able to lose the double chin through diet and exercise. Try eating a healthy diet of mostly vegetables and fruits. Supplement them with whole grains, lean proteins, and healthy fats, such as those found in nuts and avocados. You might also need to reduce your food intake.

You should also aim to exercise for forty-five minutes per day, with two of those days involving strength training. Any form of exercise works for the other five days, including regular chores you might do, such as mowing the lawn or carrying in groceries.


Maybe you’re the ideal weight and you get regular exercise but still have a double chin. If so, maybe your genes are giving you a double chin. Your DNA determines where your body stores fat, so you’re more likely to have a double chin if your genetic makeup is prone to storing fat under your chin rather than other areas in your body. You might be able to lessen it some with diet and exercise, but your genetics will make it more difficult to completely get rid of your excess submental fat.


As we age, our skin tends to become looser and sag. As the loose skin starts to pull down under the chin, fat can accumulate in the open areas there, and that could result in a double chin. If this—not weight gain—is the reason for your double chin, then a healthy diet and exercise could help some, but they alone won’t get rid of that double chin.


If you slouch when you sit, your bad posture could be contributing to your double chin. When you slouch, you weaken your neck muscles, and that produces the same effect as aging skin. Being aware of your posture and doing some exercises to strengthen your neck muscles can help. Try whistling at the ceiling. OK, you don’t actually have to whistle, but tilt your head up toward the ceiling and make the lip formation you would if you were going to whistle. Hold that for ten seconds, then repeat the process nine more times.

SculpSure® Treatments

Why do we have double chins? There are multiple reasons, and determining which of these factors is causing yours can be tricky. But once you have a double chin, for any reason, it’s often difficult to get rid of it completely. Some fat deposits can remain, no matter how much you exercise and diet. The good news? There’s a noninvasive way to get rid of fat under the chin: SculpSure® treatments.

Using SculpSure® treatments to get rid of a double chin does not involve a surgical neck lift or liposuction, which were once the only effective methods for this. The FDA-cleared SculpSure® treatments use new technology that disrupts and eliminates fat cells under the chin. The result is a slimmer looking chin and neck.

Now that you know some double chin causes, you can take steps to get rid of yours. Try a healthy diet and exercises for your body and neck. Just know that it could take several months to see results. If you aren’t getting the results you desire fast enough—or at all—consider SculpSure® treatments to achieve the look you want.
