Longer Cycles On Keto: What's The Deal?

why have my cycles gotten longer on keto

The ketogenic diet is a high-fat, very low-carb approach that has been linked to weight loss and other health benefits. However, it can also have a strange effect on your period. Some women who follow the keto diet report irregular periods, while others say their monthly cycle vanished altogether — a phenomenon called amenorrhea. In some research, 45% of female participants reported menstrual dysfunction. This could be due to the quick weight loss that the keto diet is known to cause. However, it is important to note that missed periods can be a sign of a larger health issue, so be sure to see your doctor if your periods aren’t regular.

Keto cycling can help with intense cravings for carbs and sugar

Keto Cycling: A Solution for Carb and Sugar Cravings

The ketogenic diet is a weight loss plan that involves drastically reducing carbohydrate intake, moderating protein consumption, and increasing fat intake. While this diet can lead to weight loss, better glucose control, and improved cholesterol, it is challenging to maintain due to intense cravings for carbs and sugar. This is where keto cycling comes in.

Keto cycling involves following the keto diet for a certain period, usually five to six days, and then taking a day or two off. During the "off" period, individuals can consume a higher amount of carbohydrates. This approach makes the keto diet more flexible and can help individuals stick to the diet for longer.

  • Structured Carbohydrate Reintroduction: Keto cycling allows for a planned and controlled reintroduction of carbohydrates. This can help individuals manage their cravings by knowing that they will have designated days to enjoy carbs. The structure of keto cycling can make it easier to resist cravings during the keto diet period.
  • Reduced Deprivation: The keto diet's extreme carb restriction can lead to feelings of deprivation and make cravings more intense. Keto cycling alleviates this sense of deprivation by providing regular breaks from carb restriction. This can make the overall diet more sustainable and reduce the likelihood of "falling off the wagon."
  • Metabolic Shift: The keto diet involves a metabolic shift from using glucose (from carbohydrates) to ketones (from fats) as the body's primary fuel source. This shift can reduce sugar cravings over time as the body becomes less reliant on sugar and carbohydrates. Keto cycling may support this metabolic shift by providing a gradual transition, making it easier to manage cravings.
  • Improved Energy and Mood: The keto diet can cause an initial lack of energy and "keto flu" symptoms, which can be challenging to cope with. Keto cycling can improve overall energy levels and mood by providing a break from strict carb restriction, potentially making it easier to manage cravings.

Tips for Keto Cycling:

  • Start Gradually: Begin with just one day off the keto diet to see how your body responds and how quickly you return to ketosis.
  • Choose Healthy Carb Sources: When reintroducing carbs, opt for whole foods with low amounts of sugar, such as fruit, sweet potatoes, and whole grains, instead of highly processed or sugary carbs.
  • Exercise After High-Carb Days: Engage in vigorous exercise the morning after a high-carb day to help your body burn the glycogen you consumed and get back to burning fat.
  • Avoid Overindulging: Be mindful of portion sizes and overall calorie intake during high-carb days to prevent weight gain and intense cravings.
  • Maintain a Healthy Diet: Ensure that your overall diet is nutritious and well-balanced, focusing on whole foods, quality proteins, and heart-healthy unsaturated fats.
  • Know Your Limits: Keto cycling may not be suitable for everyone. If you struggle with sugar addiction or have a history of disordered eating, consult a healthcare professional before starting keto cycling.

It can be a good option for athletes or those who are more active

Keto Cycling for Athletes and Active People

Keto cycling, also known as cyclical keto, is a less restrictive and more sustainable approach to the standard ketogenic diet. It involves following a strict high-fat, low-carb ketogenic diet for a few days, and then taking a break to eat more carbs for a day or two. This can be beneficial for athletes and highly active people who are already on a standard keto diet and want to increase their athletic performance or gain muscle.

Keto cycling can also be a good option for those who are following a strict keto diet and want a "cheat day" to break up the routine and add some diversity to their meals. This freedom of a cycling day can make you more willing to stick with traditional keto for the rest of the week without feeling deprived.

During the high-carb days, it is important to choose healthy sources of carbs such as whole grains, sweet potatoes, beans, milk, and fruit, instead of processed and sugary options. These high-carb days can be planned around workout days or high-activity days to make use of the extra carbohydrates as energy.

However, it is important to note that keto cycling may not be for everyone. It can be challenging to go back to a standard low-carb keto diet if you enjoy the cheat days too much. Additionally, since you are burning carbs for fuel instead of fat on the off days, you might not see as much weight loss progress as you would on a regular keto diet.

Before trying keto cycling, it is recommended to stick to a strict carb-restricted keto diet for at least 4 weeks to allow your body to develop its fat-burning potential.

It can be beneficial for those who want a cheat day

Keto Cycling and Cheat Days

Keto cycling is a less restrictive and more sustainable way to get the benefits of a ketogenic lifestyle while allowing for more freedom in your diet. It involves following a ketogenic diet for a few days in a row, then taking a break to eat more carbs for one or two days. This can be beneficial for those who want a "cheat day" or some variety in their eating routine, especially if they are active or want to gain muscle.

Benefits of Cheat Days

Keto cycling can be good for those who are following a strict keto diet and want a "cheat day" to break up the routine and add some diversity to their meals. This freedom can make you more willing to stick to traditional keto for the rest of the week, without feeling deprived. It can also be beneficial for athletes on a standard keto diet to increase their athletic performance.

Drawbacks of Cheat Days

However, if you enjoy the cheat day too much, it could make it hard to go back to a standard low-carb keto diet. It may also take longer to get back into ketosis, depending on how often you cycle and how restrictive you are after the cheat day. Additionally, since you are burning carbs for fuel instead of fat on the cheat days, you might not see as much weight loss progress as you would like.

How to Cheat Correctly

If you choose to incorporate cheat days into your keto diet, it is recommended to eat healthy foods as your carb sources. Instead of white bread and cookies, opt for whole grains like quinoa, buckwheat, or brown rice, or sweet potatoes, which offer some fiber and antioxidants. You can also include more high-carb fruit like apples or mangoes. It is still important to eat good protein and fats and ensure your carb sources are clean.

It can be hard to go back to a standard keto diet after a cheat day

While the keto diet is popular for its weight loss effects, it is very strict, and it can be hard to resist the occasional high-carb food. Cheat meals or days are common strategies for strict diets, but they are not ideal for keto. This is because the keto diet relies on your body staying in ketosis, a metabolic state in which your body burns fat as its primary source of energy instead of carbs.

To stay in ketosis, you need to eat fewer than 50 grams of carbs per day. Eating more than 50 grams can kick your body out of ketosis. As carbs are your body's preferred energy source, your body will use them over ketone bodies (derived from fats) as soon as a sufficient number of carbs are available. A single cheat meal can easily exceed your daily carb allowance, and a cheat day is almost certain to surpass 50 grams of carbs.

In addition, some research suggests that suddenly reintroducing a high-carb meal to a ketogenic diet may damage your blood vessels. It is also worth noting that it is easy to overeat while cheating, which may sabotage your weight loss efforts and promote unhealthy eating habits.

If you do decide to indulge in a cheat meal, it will take several days to one week to get back into ketosis, depending on your carb intake, metabolism, and activity levels. Here are some tips to help you get back into ketosis:

  • Try intermittent fasting: This may help your body shift its fuel source from carbs to fat.
  • Track your carb intake: Taking note of your daily carb intake ensures that you don't underestimate it.
  • Try a short-term fat fast: Fat fasts like egg fasts may help expedite ketosis and are very high-fat, low-carb diets meant to last only a brief period.
  • Exercise more: Physical activity depletes your glycogen stores, which are your body's stored form of carbs, thus promoting ketosis.
  • Try a medium-chain triglyceride (MCT) supplement: MCTs are a rapidly absorbed fatty acid that is easily converted into ketones.

To resist the urge to cheat on keto, try keeping carbs out of the house, roping in an accountability partner, practising mindfulness, and making a strong daily diet plan.

It can help prevent keto flu symptoms

The keto diet is a very low-carb, high-fat, and moderate-protein diet that can cause keto flu symptoms, such as nausea, constipation, headaches, fatigue, and sugar cravings. These symptoms are caused by the body adapting to a new diet consisting of very few carbohydrates. However, there are ways to prevent and alleviate these symptoms:

  • Stay hydrated: Drinking enough water is essential for optimal health and can help reduce keto flu symptoms. A keto diet can lead to rapid water loss, increasing the risk of dehydration.
  • Replace electrolytes: When following a ketogenic diet, insulin levels decrease, causing the body to release excess sodium and electrolytes. Consuming salty foods or drinking sports drinks can help maintain electrolyte balance and reduce symptoms such as fatigue, muscle cramps, and body weakness.
  • Get enough sleep: Fatigue and irritability are common during the keto diet transition. Lack of sleep can increase levels of the stress hormone cortisol, which can negatively impact mood and make keto flu symptoms worse. Aim for at least seven hours of sleep per night, and if necessary, take power naps during the day.
  • Avoid strenuous exercise: While light activities like walking, yoga, or leisurely biking may improve symptoms, it is best to avoid intense workouts during the keto flu.
  • Eat nutritious foods: Eat nutrient-dense whole foods like vegetables, meat, fish, eggs, and nuts. These foods provide essential vitamins, minerals, and protein to support reproductive health and overall well-being.
  • Consider a slower transition: Instead of immediately limiting carbohydrate intake, try reducing carbs gradually over a few days or weeks. This allows your body to adjust to the new diet naturally and can help prevent keto flu symptoms.
  • Take supportive supplements: Supplements such as exogenous ketone base, electrolyte supplements, micronutrient greens, and MCT oil can help balance electrolytes, improve micronutrient intake, and support ketone production during the transition to a keto diet.

By following these tips, you can help prevent and manage keto flu symptoms, making the transition to a ketogenic diet more comfortable and sustainable.

Frequently asked questions

Yes, it is normal for your cycle to be irregular on keto. Dramatic changes to your diet can lead to hormonal changes that may influence your menstrual cycle. Some women on the keto diet report irregular periods or their cycle halting completely. This is known as amenorrhea and can be caused by rapid weight loss, which is common on keto.

Keto can disrupt the normal release of hormones from the brain, which is necessary for a regular period. Estrogen, which regulates the menstrual cycle, can decrease with weight loss. Additionally, keto can affect the gonadotropin-releasing hormone (GnRH), which is involved in stimulating ovarian production of estrogen and progesterone, leading to potential ovulation issues.

To resume regular periods, you can try increasing your weight a little by adding more calories to your diet or reducing the intensity of your workouts. You can also consider keto cycling, which involves staying in ketosis for most days and then having higher-carb intake for a day or two. This can help stabilize reproductive hormones.
