Carb Consumption Post-Keto: What To Expect

Quitting the keto diet and reintroducing carbs will have several effects on your body and mind. Firstly, you may experience carbohydrate intolerance or a sensitive response to eating carbs, as your body has adapted to using fat as fuel and has become less efficient at processing carbohydrates. This can lead to a spike in glucose levels and insulin resistance, resulting in symptoms like abdominal pain, bloating, fatigue, and digestive issues. To counter this, it is recommended to slowly reintroduce carbs, starting with a low glycemic index and increasing by 25% each week.

Another consequence of stopping keto is weight fluctuation. Initially, much of the weight loss on keto is water weight, so when carbs are reintroduced, water retention can occur, making it seem like rapid weight gain. However, this is a natural part of the process. Additionally, constipation and gastrointestinal discomfort may arise due to the lack of fiber in the keto diet, but these issues should subside as your body adjusts.

You may also notice changes in your energy levels and mental clarity. Some people report having more energy and better concentration after reintroducing carbs, as glucose is the body's main fuel source. On the other hand, others may experience blood sugar fluctuations, resulting in jitteriness, mood changes, hyperactivity, and fatigue. It is important to monitor how your body responds and make adjustments accordingly.

It is crucial to have a plan when transitioning off the keto diet to avoid potential negative consequences. Gradually increase your carb intake, starting with unprocessed carbs like whole grains, beans, legumes, fruits, and non-starchy vegetables. Be mindful of portion sizes, as it is easy to overindulge when reintroducing carbs. Seek guidance from a dietitian to ensure a smooth transition and maintain your health and weight loss goals.

What Happens When I Stop Keto and Start Eating Carbs?

You may experience the keto flu

The keto flu is a collection of symptoms that occur when the body enters ketosis, which is a metabolic state where the body burns stored fat for energy instead of carbohydrates. This can be triggered by a very low-carb diet, like the keto diet, which restricts carbohydrates to 20 to 50 grams per day.

The keto flu can cause a range of flu-like symptoms, including:

• Weakness
• Fatigue
• Dizziness
• Headaches
• Stomach pain
• Nausea
• Vomiting
• Diarrhea
• Constipation
• Muscle soreness
• Irritability
• Trouble sleeping
• Brain fog
• Sugar cravings

The keto flu is thought to be the body's response to withdrawing from carbohydrates, as they are the body's default source of energy. The symptoms of the keto flu can range from mild to severe and can last from a few days to several weeks, and in extreme cases, up to a month.

To manage the keto flu, it is recommended to:

• Drink plenty of water to stay hydrated
• Replace electrolytes, such as salts, potassium, and magnesium
• Get plenty of rest
• Avoid strenuous exercise
• Slowly reintroduce carbohydrates and increase fat intake
• Eat more colorful vegetables

It is important to note that the keto flu is not a medically recognized condition, and if you feel very ill, it is recommended to consult a doctor.

Your body will readjust its glucose and insulin response

When you stop the keto diet and start eating carbs, your body will readjust its glucose and insulin response. This is because your body depends on carbohydrates for energy in the form of glucose. Carbohydrates are a basic nutrient that your body turns into glucose or blood sugar to make energy for your body to work.

Low-carb diets like keto can temporarily disrupt the body's glucose and insulin response. This is because your body becomes more efficient at using fat as a fuel source and less efficient at using carbohydrates. This can lead to a condition called carbohydrate intolerance or temporary insulin resistance, where your body has difficulty properly metabolizing carbohydrates.

When you stop the keto diet and start eating carbs, your body will readjust its glucose and insulin response by becoming more efficient at using carbohydrates as a fuel source again. This process can take some time, and you may experience symptoms such as abdominal pain, bloating, gas, diarrhea, constipation, and fatigue during the transition.

To help your body readjust, you can slowly reintroduce carbs back into your diet. Start with foods that have a low glycemic index, and gradually increase your carb intake over time. This will help you avoid uncomfortable side effects and maintain weight loss. It's also important to make sure you're getting enough fiber, as this is something that people tend to miss on a low-carb or keto diet.

Overall, when you stop the keto diet and start eating carbs, your body will readjust its glucose and insulin response by becoming more efficient at using carbohydrates for energy again. This process may take a few weeks, and you can help it along by slowly reintroducing carbs and making sure you're getting enough fiber.

You might gain weight

When you stop the keto diet and start eating carbs again, you might gain weight. This is because, initially, much of the weight lost on a keto diet is water weight. When you reintroduce carbs, you also reintroduce additional water; for every gram of carb, you get 4 grams of water. This can make you feel like you've gained weight rapidly, and it will be more noticeable if you've been on a keto diet for a short period.

However, weight gain will depend on several factors, including how your body metabolizes carbs, your overall diet, and your activity levels. If you've been on keto for a long time and have lost a significant amount of weight, you might not gain weight when you reintroduce carbs.

To help maintain weight loss, it's recommended to seek advice from a registered dietitian. It's also important to adopt some of the healthy behaviours you developed while on the keto diet, such as increasing your intake of lean proteins, vegetables, and wholesome carbohydrates, while still consuming healthy fats like avocado and olive oil.

Additionally, when transitioning off the keto diet, it's crucial to do it slowly and gradually. Start by adding carbs to one meal per day and track your weight and how you feel. Continue adding carbs one meal or snack at a time until you're comfortable eating them throughout the day. This slow transition will help you avoid gastrointestinal discomfort and maintain weight loss, as fibre intake is associated with more successful weight loss.

You may have more energy

Carbohydrates are one of the body's primary sources of energy. When we eat carbs, our digestive system breaks them down into glucose, which is then absorbed into the bloodstream and used as fuel. Therefore, eating carbs can make us feel energised.

However, it is more complicated than that. While you may experience an initial energy surge, your energy will drop just as suddenly as it rose, and soon you’ll find yourself putting all your remaining energy into staying focused and awake. This is because when we eat a meal high in carbs, especially refined carbs found in white bread, pasta, and sugary snacks, our blood sugar levels will quickly rise. In response, the pancreas releases extra insulin, a hormone tasked with transporting glucose from the bloodstream into cells for energy or storage. As insulin ushers glucose into the cells, blood sugar levels drop. This rapid decline in blood sugar is what triggers post-meal fatigue.

This fatigue can be avoided by eating complex carbs such as whole grains, legumes, whole fruits, and leafy greens. These foods have a lot of fibre, which slows down the absorption of glucose into the bloodstream, providing a more sustained release of energy and keeping you full for longer.

Therefore, if you stop the keto diet and start eating carbs, you may have more energy. However, it is important to eat the right kinds of carbs. If you eat simple carbs, your blood sugar levels will fluctuate, and you will experience an energy crash. But if you eat complex carbs, you will have a sustained release of energy.

You could experience digestive issues

When you stop the keto diet and start eating carbs again, you may experience some digestive issues. This is because your body has become more efficient at using fat as fuel and less efficient at using carbohydrates. This can lead to temporary insulin resistance and carbohydrate sensitivity, resulting in a variety of symptoms, including digestive issues.

The key to avoiding these issues is to reintroduce carbs slowly and gradually. Start by adding carbs to one meal per day and see how your body responds. If things go well, you can slowly add carbs to another meal or snack. This slow transition will help your body adjust to using carbs for fuel again.

It is also important to choose the right types of carbs when transitioning off the keto diet. Opt for unprocessed carbs like whole grains, beans, legumes, fruits, and non-starchy vegetables instead of processed carbs like pasta, doughnuts, and cupcakes. This is because your body has likely been missing out on fiber, and slowly reintroducing fiber-rich carbs can help improve your gut health and avoid constipation.

Another thing to keep in mind is that you may experience weight gain when reintroducing carbs. This is mostly due to water weight, as cutting carbs wipes out glycogen stores in your muscles, which helps your body retain water. However, this weight gain is temporary, and you can maintain a healthy weight by seeking advice from a registered dietitian.

In addition to digestive issues, you may also experience other physical effects when stopping the keto diet, such as blood sugar fluctuations, increased energy, and feeling hungrier. It is important to be prepared for these changes and make a plan for how you will transition off the keto diet in a healthy way.
