How Does Keto Affect Your Libido And Hormones


Could a change in diet change your sex life? Certainly! The low-carb, high-fat ketogenic diet has become very popular in recent years.

The popularity of this diet has made many people wonder how it affects various aspects beyond weight loss, and the health it improves, including sex drive.

Regarding this last point, you should know that all people who follow a ketogenic diet experience a drop in libido from the start, followed by an “explosion” in their libido. Although studies are not yet conclusive, high fat diets are generally linked to increased sex hormones, which in turn increases sexual desire, here’s why.

The main principles of the keto diet

To understand how the ketogenic diet works on the body, it’s important to understand what it actually involves. Low-carbohydrate diets, including this one, have been around for a long time (Dukan diet, Atkins diet…). But the ketogenic diet is based on foods that are supposed to direct the body to burn fat for energy, so you’re literally losing fat, not muscle.

There are many reasons for its popularity, and one of them is that it is a diet program that works quickly.

So, with the exception of a few technical details, the ketogenic diet is nothing new. However, in terms of numbers, this plan is more rigorous than other low carb diets: around 70-80% of its calories should come from fat, 15-20% from protein, and less than 5% from carbohydrates.

Ketogenic diet and libido

Many people on a keto diet experience a drop in sex drive, followed by an explosion in their sexual urges.

If you do your research, you’ll see a lot of anecdotal testimonials from people who describe a decrease in their sex drive, followed by a significant increase in their libido.

The decrease can be attributed to a period of temporary discomfort that the body experiences at the start of this diet which strongly limits carbohydrates. This period is often referred to as the keto flu in English as “keto flu”.

The increase in libido that follows is most likely due to the increase in the amount of fat consumed.

Why does sexual desire decrease?

A low amount of estrogen can impact libido in several ways. One of them is that it could lead to vaginal dryness, mood swings, and fatigue.

In some cases, low levels of sex hormones can even lead to infertility, it all depends on the time of your life.

That said, there is a big difference between adding a little more fat to your diet and going on a ketogenic diet. According to official recommendations, about 25 to 35% of your daily intake should come from fat.

The problem is, we’ve been living in a fatphobic society for years. Just look at the supermarket shelves with 0% products, low in fat, “light”, lean meats, etc.

So if there are sexual dysfunction or fertility issues due to low fat intake, it wouldn’t be a surprise.

Eating more fat increases libido

There are a lot of factors to consider when thinking about how the ketogenic diet improves libido. Just feeling good about your body, for example, can increase your libido.

It is known that the ketogenic diet improves (after a period of keto-adaptation) the energy level, which could also improve the quality of one’s sex life.

Along with these aspects, we must not forget that sex hormones are made by the body with a lipid substance that many people still believe to be dangerous for health: cholesterol, which the ketogenic diet makes a big part of.

The bottom line is if you’re not yet ready to jump into a ketogenic diet if you see someone eating an egg white and throwing the yolk… eat it! Don’t forget what the ancients used to say: fat is life…
