Reap the Benefits of CrossFit and Intermittent Fasting: A Comprehensive Guide

CrossFit and Intermittent Fasting: A Comprehensive Guide

The CrossFit nutrition recommendation is to eat meat, vegetables, nuts and seeds, some fruit, little starch, and no sugar while keeping a balanced diet. A review article published by John Hopkins University concluded that intermittent fasting could boost physical performance and detailed how men and women could benefit from it. However, can these two nutritional approaches be combined? Read on to learn more about how CrossFit and intermittent fasting can work together to help you reach your health and fitness goals.

Breakfast: The Most Important Meal of the Day

It’s no secret that breakfast is the most important meal of the day. Eating as soon as you wake up to break the fast helps set you up for healthy eating for the rest of the day. But what if you are looking for a way to mix CrossFit and intermittent fasting?

Intermittent fasting (IF) is a type of dietary restriction. It involves going for a predetermined period of time without eating anything. During this time, your body is relying on stored energy from fat and muscle to power you through. In order to maximize the potential benefits of IF, you need to ensure you are eating the right food during your eating window.

Get Grass-Finished Meat Delivered To Your Doorstep With CrossFit and Intermittent Fasting

The evidence suggests that you can mix CrossFit and intermittent fasting, although the success depends on what you are currently eating. For example, if you are eating a high-carb diet, then you may have difficulty transitioning to an intermittent fasting plan. Instead, you should focus on eating healthy, grass-finished meats and vegetables to fuel your body and help you reach your goals.

With an intermittent fasting model, a general schedule may have a 16-hour fasted period with an 8-hour feeding window. This means you are fasting for 16 hours in between meals. Alternatively, you can also try the 5:2 diet, where you consume only 500–600 calories on two non-consecutive days of the week.

CrossFit and Intermittent Fasting: A Perfect Combination

It takes over 24 hours of fasting before your body goes into a starvation mode and taps into muscle for fuel. Doing CrossFit on an empty stomach should not induce this mode, so it is safe to do CrossFit while fasting. Combining CrossFit and intermittent fasting can result in burning body fat for fuel as your main energy source instead of burning carbs for energy.

To get the most out of CrossFit and intermittent fasting, you should focus on eating the right food during your eating window. Eating healthy, grass-finished meats and vegetables will help fuel your body and support your goals. Additionally, it is important to stay hydrated and get enough sleep when incorporating CrossFit and intermittent fasting into your routine.


CrossFit and intermittent fasting can be a great combination if you are looking to improve your health and fitness. Eating healthy, grass-finished meats and vegetables during your eating window, while also staying hydrated and getting enough sleep, will be key to success. With a balanced approach and proper nutrition, there is no reason why you cannot reap the benefits of CrossFit and intermittent fasting.

Does CrossFit work with intermittent fasting?

Intermittent fasting is often practiced within the CrossFit community, with the most popular protocols being the 16:8 method, the 5:2 method, and the 1:1 method. The 16:8 method involves fasting for 16 hours and then having an 8-hour window to eat.

Is it permissible to exercise while following an intermittent fasting plan?

Yes, it is acceptable to exercise while fasting as the combination of fasting and sprint training has been shown to provide considerable benefits when it comes to weight loss and muscle gain. Hormone optimization is an important factor to consider when attempting to lose weight and build muscle, and fasting combined with sprint training does this effectively.

What type of nutritional plan do Crossfitters typically follow?

In summary, CrossFit recommends the Zone Diet, which emphasizes a balanced intake of lean proteins, vegetables, nuts, seeds and low glycemic fruit, while limiting starches and refined sugar. This dietary pattern is beneficial for health, as it may help control hunger and reduce levels of blood sugar and inflammation.

Is it possible to shed pounds quickly by doing CrossFit?

Experts in the field concur that CrossFit can facilitate rapid weight loss; for an average person, participating in CrossFit for five-plus hours a week should lead to burning roughly 3,000 calories.
