If youre new to the keto diet, you may be wondering how to best supplement your new low-carb and high-fat lifestyle with exercise, especially if youre used to being active.

While there are some things to be mindful of, exercise on the keto diet is certainly encouraged and comes with plenty of health benefits.

In this article well discuss the following:

Dont! When the goal is fat loss, a common misconception is to restrict calories while also adding in more exercise, typically cardio, in an effort to lose as much weight as possible. This is not a helpful nor healthy approach to weight loss on the ketogenic diet.

By severely restricting calories and supplementing it with high-intensity or prolonged cardio workouts, you will burn out. This is a recipe for feeling mentally and physically exhausted, and will not lead to significant weight loss. The more you adhere to this approach, the more likely you will only put more stress on your body.

Some side effects of this are an increase in chronic inflammation and even the accelerated aging of your cells. Its simply not a sustainable way to lose weight and can hurt your body in the end.

By eating nutritious whole foods that are also low in carbs along with a moderate amount of protein and high-fat foods, you will naturally eat less because of this diets appetite-suppressing effects[1]. And then of course, weight loss will come.

Moderate amounts of low-intensity cardio is great for your body, so do it! Activities like walking, swimming, hiking, and cycling are all excellent workouts that are also health-improving.

In regards to cardio exercise, what is not helpful is endless hours of running, extreme spinning, or hard-core classes.

Most people think of cardio as the ultimate fat-burning method, but in the end, its a race you cannot win. Its not a sustainable lifestyle for the majority of people.

Here are some reasons why:

Weight training is perfectly fine on the ketogenic diet, but you may need to make some small adjustments to fit your carb needs for the amount of exercise.

Its generally a good idea to consume 15-30 grams of fast-acting carbohydrates, like fruit, up to 30 minutes before your workout and up to 30 minutes after.

This ensures your muscles are getting the proper amount of glycogen to perform during training and also during recovery. Your carbs will be used for this specific purpose without the risk of leaving ketosis.

When doing this form of exercise, be sure to focus on your major muscle groups and add some squats into the mix.

The ketogenic diet has the added benefit of muscle-sparing effects that help you preserve and build lean mass.

This kind of exercise includes intense bursts of anaerobic exercise, such as sprinting with short intervals for recovery.

Similar to weight training, carbohydrates are the primary fuel source for HIIT, so your typical keto diet alone will most likely not be enough energy for these types of workouts.

This includes activities like stretching and yoga, and are great for the ketogenic diet. These exercises are helpful for stretching your muscles, improving muscle range motion, and supporting your joints.

Increasing your flexibility can help to prevent injuries that are typically caused by the shortening of the muscles over time, so do it!

Exogenous ketones are a pretty hot product on the market for keto dieters. These are ketones that are taken externallytypically in the form of a pill, liquid, or powderas opposed to being

naturally produced by your body, and are an excellent way to supplement your ketogenic diet, especially if you are very active.

If you plan on engaging in more intense exercise and prefer not adding more fast-acting carbs before and after your workout, try supplementing your diet with exogenous ketones instead.

This is a great way to get the energy your body needs for a longer workout while still being able to jump right back into ketosis faster afterwards.

Supplementing your ketogenic diet with moderate exercise has been shown to provide some significant benefits. In one three-hour-long study on athletes on a low-carb diet, they were seen to burn 2-3 times more fat than those on a high-carb diet[2].

This same study also showed these low-carb athletes used and replenished the same amount of muscle glycogen as their high-carb counterparts.

Other benefits include:

There are a lot of carb-heavy philosophies that give ketosis a bad reputation when it comes to exercise, but the truth is that low-carb diets like the ketogenic diet can work well with low-to-moderate forms of exercise and yield plenty of health benefits.

If you have a very active lifestyle and are interested in going keto, it can absolutely work, you just may need to make some small adjustments to your diet.
