While many people turn to the keto diet for health reasons or as a solution to weight loss, this high-fat and low-carb diet can also have the added benefit of an increased sex drive.

Diet plays a major role, and by eating the right foods and getting the right balance of nutrients, you’ll be on a fast path to an increased libido and greater sex drive—something sexy lingerie and vanilla-scented candles can’t do on their own!

The Rundown on Carbs

Carbs supply your body with glucose which is then converted into energy—something your body greatly needs to function properly.

If your body has enough glucose for energy, excess glucose consumed will be stored away for later use in the form of glycogen. However, when these glycogen stores are full, your body can convert the excess carbs into triglyceride molecules and store them as fat.

So how do carbs interfere with sex? Basically, by eating too many carbs, this can negatively affect your sex life since it’s influencing things like your weight, mood, and energy levels.

Let’s look at a few significant ways the ketogenic diet—which is low in starches and high in fat—can give your libido a lift:

More energy will get you going

Sometimes the truth is, you’re just too tired for sex! People come home from a long day of work filled with various demands or maybe demanding kids, and the last thing on their mind is to hop into bed for anything other than sleep.

On top of that, the food many people eat isn’t giving them the energy they need. While carbs are your body’s main source of energy, they work against your energy levels.

A low-carb diet that is high in other important macronutrients like proteins and fat can steady blood sugar levels and provide slow, sustained energy all day you can be focused and energized.

Your sex drive is greatly determined by your energy levels, so if your body isn’t getting proper fuel, don’t expect it to get itself ready for much sexual activity.

Shedding pounds boost testosterone levels

Low sex drives, low sperm count, and erectile dysfunction1 in men have all been linked to low levels of testosterone. According to WebMD, a lack of testosterone in women has also been linked to low sex drives.

So what’s killing our testosterone and how do carbs play into this? Simply eating carbs won’t cause a person to become overweight or obese, and there are several other factors at work here, including lifestyle and genetics.

However, by consuming a large number of carbs—especially simple carbs—without burning them off, they will get stored away as fat. This elevates the body mass index (BMI) which has been correlated to lower levels of total testosterone.

Additionally, insulin resistance that results from diets that are high in refined carbs also brings down testosterone. By opting for a low-carb, high-fat diet, your body will stop trying to locate glucose and will begin to naturally use its own stored fat.

As the fat in our bodies begin to disappear, testosterone rises, as does your sex drive.

High fat intake raises estrogen levels

One study2 examined women’s fat intake and showed that women on a low-fat diet had significantly lower estrogen levels. For women on a high-fat diet, the results were the opposite, and they showed higher levels of estrogen.

Low levels of estrogen can have a big impact on women’s sex drive, as it can often lead to vaginal dryness, which can give way to uncomfortable intercourse along with unstable moods and sleep patterns.

Get in the mood with less stress

Diets that rely heavily on carbs and less fat leave your body experiencing peaks in blood sugar, followed by a crash. When that happens, your adrenal glands kick in with stress hormones to increase blood sugar and stabilize the body.

These stress responses—especially increased levels of cortisol—have been shown to decrease arousal and sex drive.

In another study3 by the National Institute of Health, researchers looked at the individual differences in women’s cortisol response to sexual arousal.

Results revealed that women who showed an increase in cortisol also had lower scores on the Desire, Arousal, and Satisfaction domains of the Female Sexual Function Index.

In other words, when you’re body’s stress levels are elevated, it’s much harder to “get in the mood” simply because your body is busy dealing with perceived threats.


By now you should know, what you eat matters and can impact your body in unexpected ways. Opting for a low-carb diet which also incorporates enough protein and fat is a natural, healthy, and effective way to give your sex drive a boost.

Not only that, diets like the keto diet can transform your body and give you the extra confidence needed to look and feel good in bed!
