They may also feel very tired or experience digestive issues when they reintroduce the carbs they once enjoyed, and even regain a bit of weight due to higher insulin levels. This phenomenon (known as carbohydrate intolerance) is a normal response when the body is adapting to these changes in diet.
Eating carbs after following a keto diet can cause a phenomenon called "carbohydrates refeeding" or "keto-flu" which can cause symptoms such as fatigue, headaches, and irritability. This is because your body needs time to adjust to the changes in your nutrient intake.

Fortunately, the answer is no. You will not necessarily regain the weight, provided you are thoughtful during and after the transition. There are many reasons people choose to stop maintaining a high-fat diet that keeps you in a state of ketosis.
It is normal to gain back some weight after stopping a particular diet – sometimes as much as 5-10 pounds, immediately. You should not worry too much about this, as it is not fat that you are regaining that quickly. In the case of the Keto diet, this will be primarily due to water weight.
Ketosis Isn't Forever.
It's recommended that you follow this diet to arrive at a state in which your body adapts to burning fat and glucose stores for fuel. Then you'll want to take an occasional ketosis holiday, adding a serving of unprocessed, whole grains to allow your body to chance to work less hard.
Even if you are in ketosis and counting your calories, you may reach a weight loss plateau or keto plateau. Over time, the body begins to adapt to changes in diet and begins needing fewer calories in order to keep going. There is no need to worry as there are other ways to measure your progress.
To reverse carbohydrate intolerance, it's important to add carbs back in slowly, starting with small servings and low-GI foods like fruits, vegetables, and whole grains. These foods have “good carbs,” which are higher in fiber, which can help prevent large blood sugar spikes.
Gradually Increase How Many Carbs You Eat
Add in an additional 10 g of carbohydrates per day for the first week, says Keene. Opt for carbs from healthy sources like whole grains, beans, fruits, and starchy veggies. Grab a pad of paper and track your weight and how you feel.
So how long does it take for excess carbohydrates to turn to body fat? Once a meal is consumed, your body either uses the calories as fuel, or stores the calories in fat cells to be used a later time.

Keto cycling doesn't have a strict definition. Some people choose to have five or six days on keto followed by a day or two off. Others will do keto for 10 to 12 days followed by three to four days off. Devine typically doesn't recommend taking more than two days off keto.

Keto stabilizes blood sugar levels so a sudden cheat day can have the potential to cause dangerous spikes to your blood sugar levels. For the average person, this may cause you to feel nauseous for a few days at most, but for diabetics, this could be potentially life-threatening if too much sugar is consumed.
Usually, when a person does not lose weight on the keto diet, it is because they have not achieved ketosis. The most common reason for not getting into ketosis is not cutting back enough on carbs. According to a 2019 article on the ketogenic diet, carbohydrates should represent only 5–10% of a person's calorie intake.
People tend to gain weight after following the keto diet for several reasons: They don't exercise enough. They return to eating high-sugar, ultra-processed foods [1] They don't eat enough fiber.
Sudden weight gain on keto is often due to an overconsumption of fats like coconut oil, butter, olive oil, and other types of oils and fats. While these ingredients are perfectly acceptable on the keto diet, too much can lead to sudden weight gain.
A prolonged 1,200 calorie-per-day diet can slow metabolism, so it is best to only do it short-term. There are risks to consuming too few calories, including: Not getting adequate nutrition.
Cut the carbs—When you cut out refined carbs like white bread, rice, bagels, pasta, cookies, candy and chips and focus on nutrient- and fiber-rich carbs such as vegetables, and low-glycemic fruits, you start to lose belly fat, because, once again, your body is burning fat for fuel.
The best way to tell if you have visceral fat is to measure your waist. The waist circumference is a good indicator of how much fat is deep inside the belly, around the organs. For women, your risk of chronic disease is increased if the waist circumference is 80 cm or more and for men 94cm or more.
