Ultimate Guide To Keto And Intermittent Fasting

In this post, we’ll examine the advantages of combining intermittent fasting with a ketogenic diet and how to do it correctly for the best outcomes.

What is the Keto Diet?

A high-fat, low-carb diet that has gained popularity recently is the ketogenic diet, or keto for short. The diet’s objective is to cause the body to start using ketones instead of glucose as its main fuel source. Ketones are created by the liver when the body is in a state of ketosis.

In general, persons who follow the ketogenic diet try to get 70–75% of their daily calories from fat, 25–30% from protein, and only 10–15% from carbohydrates. In most cases, this entails choosing low-carb veggies, meat, fish, nuts, and seeds over high-carb items like bread, spaghetti, and sugary snacks.

What is Intermittent Fasting?

A practise of eating known as intermittent fasting alternates between periods of fasting and eating. There are many ways to practise intermittent fasting, but some of the most well-liked ones are as follows:

  • 16/8 method: The 16/8 approach calls for a 16-hour period of fasting and an 8-hour interval for eating.
  • 5:2 method: Using the 5:2 technique, you eat normally for five days a week while keeping your calorie intake to 500–600 calories on the other two.
  • Alternate-day fasting: This entails going without food entirely or merely consuming a little amount of calories every other day.

Many health advantages of intermittent fasting have been demonstrated, such as increased insulin sensitivity, decreased inflammation, and enhanced cardiovascular health.

Combining Keto and Intermittent Fasting

Although while the keto diet and intermittent fasting have both been proven to be successful weight loss methods on their own, combining the two can offer even more advantages. Here are a few advantages of combining intermittent fasting with the keto diet:

Increased Weight Loss

Both the ketogenic diet and intermittent fasting can aid in weight loss, but when used in tandem, the effects can be considerably more dramatic.

Your body will turn to stored fat for energy as it will have even less carbohydrates to choose from when intermittent fasting is added to the equation. This may result in a quicker loss of weight and a lower percentage of body fat.

Improved Insulin Sensitivity

A hormone called insulin aids the body in controlling blood sugar levels. Your body makes insulin when you consume carbohydrates to assist in transferring glucose into your cells for energy.

Increased Autophagy

The body naturally disposes of damaged, old cells through a process known as autophagy. This mechanism has been associated with a lower incidence of age-related disorders including Alzheimer’s and Parkinson’s and is crucial for maintaining the health of cells.

When paired with the ketogenic diet, intermittent fasting has been proven to promote autophagy to even greater effect. The keto diet can further boost autophagy by lowering carbohydrate intake, which can assist to promote cellular health and lower the risk of age-related disorders.

Reduced Inflammation

The body uses inflammation as a natural defence against damage and illness. However, persistent inflammation can cause a number of health issues, including as cancer, arthritis, and heart disease.

It has been demonstrated that both the ketogenic diet and intermittent fasting lower inflammatory markers in the body, which can lower the risk of chronic disease and enhance general health.
