Everything You Need to Know Before Trying the Cyclical Ketogenic Diet

Updated 03/23/18

By now you've probably heard a friend, family member, or perhaps even a celebrity touting the benefits of the popular ketogenic diet, which cuts carbs and increases fats so the body is forced into a fat-burning state. If that sounds extreme, fear not. A cyclical version of the diet exists, and it may suit your lifestyle better.

We tapped wellness doctor and author Josh Axe, DNM, DC, CNS, who recently created a diet and fitness plan based on the ketogenic method, to give us the scoop on this way of eating. In addition to expanding on the specifics of a cyclical ketogenic diet, we asked this nutrition expert to tell us who makes a good candidate, what the biggest misconception is, and what side effects you might experience. Basically, consider this your CKD 101.

What It Is

According to Axe, a cyclical version of the ketogenic diet is characterized by the fact that it alternates between high- and low-carb days. "Typically, someone following this plan would eat more carbs about one to two days per week, aiming to get 100 grams of net carbs or more on higher-carb days," he explains, "The other five to six days of the week, they would restrict carbs to about 25 to 35 net grams per day, with about 75% more of their calories coming from fat." The benefit of eating this way, as opposed to the traditional keto diet, is replenishing muscle glycogen, which is an energy source.

Additionally, notes Axe, carb-cycling can help with metabolism, breaking through plateaus experienced in weight-loss journeys, and exercise recovery.

Who It's For

As for who makes a good candidate for the cyclical ketogenic diet, it seems that more physically active types are at the top of the list. "If you're someone who is athletic, cycling may be a good strategy for keeping your energy levels up and supporting muscle growth and recovery." If you're someone who tried to go keto but found it too restrictive—or found that the side effects (explained below) made it too difficult to totally commit—you might also benefit from carb-cycling since it allows a bit more flexibility.

Biggest Misconceptions

Don't let the "high fat" description fool you, as Axe tells us that those who consider the cyclical ketogenic diet (or any keto diet) to be a free-for-all for bacon, ice cream, and other fatty indulgences should think again. "One of the biggest mistakes I see is when they indulge in any and all types of fatty or high-protein foods, many of which are highly processed and not very healthy," he explains, "Just because a food provides fats or won't throw you out of ketosis doesn't mean it's good for you." He recommends using whole, clean foods as a means of getting both fats and protein.

For example, opt for wild-caught salmon over processed meats or grass-fed butter over refined oils and get your carbohydrates from whole grains and starchy veggies.

What to Expect

While many have found the cyclical ketogenic diet (as well as traditional keto) to be an effective way to burn fat, it's not without potential side effects. And as Axe is quick to point out, different bodies can have different results based on factors like weight, age, medical history, and frequency of physical activity. "When you first begin the ketogenic diet, you might experience some temporary side effects like low energy, brain fog, trouble sleeping, or cravings for sugar/carbs," he elaborates, "these feelings are totally normal when you drastically restrict carbohydrates."

But while anyone interested in this type of diet should be aware of these potential side effects, the potential gains might make this interim period worth it. "With patience, these issues usually go away within a range of a few days to several weeks," Axe reports. And after cycling a few times, dieters very likely could see these symptoms subside.

Now that we know a bit more about who's a good candidate for the cyclical ketogenic diet as well as what to expect when switching over to this way of eating, we have to admit one definite plus is the fact that—unlike straightforward low-carb diets—we may still get to indulge in the occasional slice of pizza. So there's that. Would you give it a whirl?
