Carb Reintroduction On Keto: What To Expect

The Ketogenic Diet is a low-carbohydrate method of eating that helps people with diabetes, epilepsy, autoimmune disorders, acid reflux, inflammation, hormonal imbalances, and other issues. When on the keto diet, it is recommended to stay under 20g of carbs per day to stay in deep ketosis. However, the number varies from person to person, and going over the limit can have different effects. Some people report feeling bloated, having stomach cramps, or experiencing increased arthritis and migraine symptoms when consuming more than 20g of carbs. Others find that it takes them about a day to get back into ketosis after going over the limit. It is important to note that going over the carb limit can lead to a slippery slope mentality, where one carb-heavy meal turns into days or weeks of falling off the diet.

Weight gain and water retention

When reintroducing carbs after following a keto diet, it is possible to experience weight gain and water retention. The extent of these effects can vary depending on individual factors, such as the number of carbs consumed, the duration of the keto diet, and one's level of physical activity.

Weight gain can occur due to an increase in calorie intake when reintroducing carbs. The body will start burning glucose from carbs instead of ketones, which can slow down weight loss or lead to weight regain. The weight gain may be influenced by the duration of carb consumption, as prolonged periods of high-carb intake can impact weight more significantly.

Water retention is another potential consequence of reintroducing carbs. Carbs are stored as glycogen in the muscles, and each gram of glycogen binds to water molecules, leading to increased water weight. This can result in a higher number on the scale, but it is important to distinguish it from fat gain. The water weight gain may be temporary and can be reduced by returning to a low-carb diet.

The keto diet typically recommends keeping carb intake under 20 grams per day to maintain ketosis. However, some individuals can consume up to 30 or 50 grams of carbs while still remaining in ketosis. Exceeding this limit can lead to a reset of the ketosis process, and it may take about a day to get back into ketosis by restricting net carbs again.

It is worth noting that the effects of reintroducing carbs can vary from person to person. Some individuals may experience bloating, stomach cramps, fatigue, or other physical discomforts when increasing their carb intake. Additionally, carb cravings can return, making it challenging to maintain a low-carb diet.

Stomach issues and lethargy

When reintroducing carbs into your diet after a period of keto, it is possible to experience stomach issues and lethargy. This is due to the body readjusting to a new fuel source, with glucose taking the place of ketones. The stomach issues can manifest as bloating, stomach cramps, and even diarrhea. These symptoms can be accompanied by lethargy, headaches, and poor sleep.

The severity and duration of these symptoms can vary depending on the individual and how long they have been on the keto diet. For some, consuming more than 20 grams of carbs in a day can lead to these issues, while others can tolerate up to 35 grams without experiencing any adverse effects. However, it is generally recommended to stay under 20 grams of carbs per day to maintain "deep" ketosis and maximize the benefits of the keto diet.

The transition period from keto to a higher-carb diet can be challenging, and it is important to listen to your body and make adjustments as needed. For some, the stomach issues and lethargy may be a sign that their body is struggling to adjust to the new diet, and it may be necessary to gradually increase the amount of carbs over time. This gradual approach can help reduce the intensity of the symptoms and make the transition smoother.

It is worth noting that the keto diet itself can also cause stomach issues and lethargy, especially during the initial adjustment period. However, for some individuals, reintroducing carbs may trigger these symptoms, highlighting the importance of a balanced and individualized approach to nutrition and diet.

If you are experiencing stomach issues and lethargy after reintroducing carbs, it may be beneficial to assess your carb tolerance and adjust your diet accordingly. It is also important to stay hydrated, get enough rest, and listen to your body's signals to support your overall well-being during this transition.

Carb cravings

When adhering to a keto diet, it is generally recommended to stay under 20 grams of carbs per day to ensure "deep" ketosis. However, this number may vary from person to person, and some individuals can remain in ketosis while consuming up to 30 or even 50 grams of carbs. Nonetheless, exceeding this limit can lead to a disruption in ketosis and the associated benefits.

The challenge with carb cravings arises when individuals accidentally or intentionally consume more carbs than their limit allows. This can happen due to a lack of awareness of carb content in certain ingredients or during social occasions where carb-heavy foods are prevalent. Giving in to carb cravings can lead to a "slippery slope" mentality, where one carb-filled meal turns into days or weeks of deviating from the keto diet.

To manage carb cravings, it is crucial to understand that a minor slip-up doesn't have to turn into a full-blown relapse. While it may take 24 hours to reset and get back into ketosis, it's important to remember that one carb doesn't obligate you to eat every carb. Enjoy the carbs that are worth it to you, and then get right back on track. This mindset can help prevent a single indulgence from becoming a long-term deviation from your keto goals.

Additionally, it's essential to be mindful of the potential physical effects of giving in to carb cravings. Consuming too many carbs can lead to bloating, stomach cramps, fatigue, and water weight gain. These unpleasant side effects can serve as a reminder of the importance of sticking to your keto plan.

Arthritis and migraines

While the long-term risks and consequences of a low-carb diet are still being researched, some health experts have expressed concern over the potential negative health consequences of such diets. One concern is the increased risk of developing gout, a form of arthritis caused by excess uric acid in the body. Since many low-carb diets emphasise animal-based fat and protein, people following this diet may eat enough purine to trigger a gout attack.

Some people who have tried the keto diet have reported that their arthritis pain has either reduced or disappeared completely. One person reported that their arthritis flare-ups had reduced significantly, while another person with osteoarthritis reported that their pain was gone after trying the keto diet for two weeks.

However, it is important to note that the keto diet may not work for everyone, and individual experiences may vary. Some people have reported that their arthritis flares up when they consume more than a certain amount of carbs. For example, one person on Reddit mentioned that if they go over 35g of carbs, their arthritis flares up, and their migraines increase.

Therefore, while the keto diet may provide relief for some people with arthritis, it is crucial to approach it with caution and consult a healthcare professional before starting any new diet, especially if you have a medical condition.

Glycogen stores and ketosis

Glycogen is a stored form of glucose, which is stored in the liver and muscles. For every 1 gram of stored glycogen, there are about 3 grams of water. When you eat fewer carbohydrates, your body will start to break down and use the glycogen in your liver, releasing it into the bloodstream to be used to generate energy. The glycogen stores in your muscles will also decrease as they get utilised for energy production within the muscles themselves. As your body uses up its glycogen stores, the water once attached to it becomes released and excreted. Thus, as you use up your glycogen, you also lose some water weight.

The prevailing theory regarding the initiation of ketosis is that ketone body production is triggered once the body depletes its glycogen stores. However, this glycogen depletion hypothesis has been challenged by research showing that keto-adaptation was not related to glycogen levels. In fact, long-term ketosis has been shown to reduce liver glycogen content.

When reintroducing carbs after keto, the body will start to break down and use the newly ingested carbohydrates, which will be prioritised as an energy source over fat. This means that the body will revert to a state of glycolysis (using sugar for fuel) rather than ketosis (using fat for fuel). The shift back to glycolysis will depend on individual factors, such as the duration of the keto diet, the amount of carbs ingested, and the person's metabolic health.

The shift back to glycolysis can have several effects on the body. In terms of weight loss, it may slow things down or cause water weight gain. Additionally, individuals may experience varying side effects, such as bloating, stomach cramps, fatigue, headaches, and achiness. These side effects are likely due to the body's adjustment to the new fuel source and the resulting changes in metabolism.

To summarise, when going back on carbs after keto, the body will utilise the ingested carbohydrates and deplete its glycogen stores, resulting in a shift from ketosis to glycolysis. This transition can have varying effects on weight loss and may be accompanied by side effects as the body adjusts to the new fuel source.
