Keto Body Repairs: How Long Before You See Results?

The ketogenic, or keto, diet is a high-fat, low-carbohydrate diet that has been used for over 100 years. Originally a therapeutic nutrition plan to treat epilepsy, it is now primarily used to promote weight loss and manage blood sugar levels. The diet involves limiting your carbohydrate intake to under 50 grams per day, which forces your body to use fat for energy instead of glucose. This metabolic state is called ketosis. It can take anywhere from two to four days, or even longer, to enter ketosis, depending on factors such as age, metabolism, and physical activity level. While the keto diet can lead to rapid weight loss, it can also have negative side effects, including keto flu, constipation, and micronutrient deficiencies.

How long does it take to enter ketosis?

Entering ketosis usually takes anywhere from two to four days, but this can vary from person to person. Some people may find it takes a week or longer to reach this state.

Factors that influence the time it takes to enter ketosis:

• Carbohydrate, fat, and protein intake
• Physical activity level
• Age
• Basal metabolic rate
• Illnesses that affect the thyroid (hypothyroidism)
• Lifestyle factors such as exercise, sleep, and stress

Tips to achieve ketosis:

• Eat 20–50 grams of carbs per day
• Track your carb intake
• Limit eating out at restaurants
• Be aware of hidden carb sources
• Increase your intake of high-quality fats
• Try intermittent fasting
• Exercise more
• Test your ketone levels regularly

Signs that you have entered ketosis:

• Flu-like symptoms ("keto flu") such as headaches, fatigue, nausea, bad breath, and increased thirst
• Accelerated weight loss
• Dehydration from body water loss
• Ketones in the bloodstream and urine

Ways to measure ketone levels:

• Urine testing strips: A cheap and simple way to test for ketones in the urine, but may not be as accurate as other methods.
• Ketone breath meter: A meter that flashes a colour to indicate whether you are in ketosis and what your ketone levels are.
• Blood ketone meter: A tool that measures ketone levels in the blood, similar to a glucometer for testing blood glucose levels.

What are the signs you're in ketosis?

Signs You're in Ketosis

The "keto flu" is a common experience for people starting a ketogenic diet. This includes symptoms such as fatigue, mental fogginess, irritability, headaches, and nausea. However, there are several other signs that your body has entered the fat-burning state of ketosis.

• Weight Loss: You will likely experience rapid weight loss in the first week of a keto diet, primarily due to the reduction of water weight.
• Bad Breath: Ketones, specifically acetone, are released from the body through breath and urine, resulting in an unusual, fruity odour.
• Increased Ketones in the Blood: One of the defining features of a keto diet is a reduction in blood sugar and an increase in ketones. This can be measured through a blood ketone meter, which is the most accurate method.
• Increased Ketones in the Breath: A breath analyser can be used to monitor acetone, one of the three main ketones in the blood during ketosis.
• Appetite Suppression: Many people on a keto diet report decreased hunger, possibly due to alterations in hunger hormones and increased protein intake.
• Increased Focus and Energy: After the initial "keto flu" phase, many people experience increased focus and energy, as their bodies start burning ketones instead of glucose.
• Short-Term Fatigue: The switch to a keto diet can cause weakness and fatigue, as it takes time for the body to adapt to burning fat for fuel instead of carbohydrates.
• Short-Term Decreases in Exercise Performance: The reduction in carbohydrate intake leads to a decrease in glycogen, the most efficient fuel source for high-intensity exercise. This can cause a temporary decline in exercise performance.
• Muscle Spasms and Cramps: The loss of water weight and reduced glycogen levels can lead to muscle cramps and spasms due to dehydration and electrolyte imbalances.
• Dry Mouth: As the body loses water weight, you may experience increased thirst and a dry mouth. Dehydration is a common side effect of ketosis and can lead to more serious health complications if not addressed.
• Fatigue or Sleep Changes: Switching to a keto diet can disrupt your sleep patterns, causing nighttime waking or difficulty falling asleep. This is usually a short-term effect.
• Change in Bowel Movements: Dietary changes can lead to digestion issues such as constipation and diarrhoea.

What are the risks of staying on a keto diet?

Staying on a keto diet for a long period of time can be risky. Here are some of the potential risks associated with long-term adherence to a keto diet:

• Nutrient deficiencies: The keto diet restricts several food groups, including nutrient-dense fruits, whole grains, and legumes. This may result in deficiencies of vitamins and minerals such as calcium, vitamin D, magnesium, phosphorus, folate, thiamin, and vitamins A, B6, B12, C, E, and K.
• Liver problems: The liver has to work hard to metabolize the large amount of fat in the keto diet. This could worsen any existing liver conditions.
• Kidney problems: The high intake of animal foods and protein in the keto diet may cause kidney stones and overload the kidneys, leading to a potential increase in the risk of chronic kidney disease.
• Digestive issues: The keto diet is low in fiber due to the restriction of high-carb fruits, starchy vegetables, whole grains, and beans. This can lead to digestive discomfort and constipation.
• Bone health: The keto diet has been associated with impaired bone health and reduced bone mineral density in several studies.
• Chronic diseases and early death: There is evidence suggesting that long-term, animal-based, low-carb diets like keto may lead to higher death rates from heart disease, cancer, and all causes. However, vegetable-based low-carb diets have been associated with lower death rates from these causes.
• Fuzzy thinking and mood swings: The keto diet may cause confusion and irritability due to the low intake of healthy carbohydrates, which are the brain's preferred energy source.
• Water loss: In the initial stages of the keto diet, water loss can occur before fat loss, leading to dehydration.
• Gastrointestinal issues: Common side effects include constipation, diarrhea, nausea, and vomiting, with diarrhea being more frequent due to the body's difficulty in absorbing the high-fat content of the diet.
• Reduced athletic performance: Research has shown that athletes may experience reduced performance in high-intensity cycling and running tasks after being on a ketogenic diet for a few days.
• Vitamin and mineral deficiencies: The restriction of fruits and vegetables on the keto diet may lead to a lower intake of important vitamins and minerals, including folate, thiamin, and vitamins A, B6, B12, C, E, and K.
• Keto flu: Some people may experience the "keto flu," which includes symptoms such as fatigue, mental fogginess, irritability, headaches, dizziness, nausea, and constipation. These symptoms usually improve within a few weeks, but it's important to monitor them and stay hydrated.
• Weight regain: Due to the restrictive nature of the keto diet, people may regain any lost weight when they return to their initial eating patterns.

What are the challenges of the keto diet?

The keto diet is a high-fat, low-carb, and moderate-protein eating plan. It is advertised as a weight-loss wonder, but it is actually a medical diet that comes with serious risks. Here are some of the challenges of the keto diet:

Keto-adapting

During the first month, the body goes through an adaptation process as it switches from burning sugar to burning ketones for energy. Common symptoms during this phase include fatigue and flu-like symptoms. These symptoms are similar to those experienced in any kind of detox program and are not necessarily a sign that the diet is harmful. However, it is important to consult a doctor if these symptoms arise to ensure that everything is moving forward as expected.

Cheating

Cheating on the keto diet can be detrimental. Eating a larger amount of carbs even once can bounce the body out of ketosis, and it may take several days to get back into it. Therefore, it is important to avoid cheating on the keto diet and to monitor ketone and blood sugar levels closely.

Carb creep

It is important to keep track of daily carb intake, especially in the beginning. Over time, it is easy to let the number of carbs creep up, which can cause ketone levels to drop.

Phases of the diet

The long-term necessity of the keto diet is unclear. Some experts recommend staying on the diet for 18 to 24 months, while others suggest that it should only be a short-term dietary change to jump-start weight reduction.

Food restrictions and repetition

The keto diet is very restrictive, and it can be challenging to eat a variety of foods. It involves eating just 20 grams of carbs per day, which can be difficult to stick to. As a result, meals can become repetitive, with a lot of bacon, cheese, eggs, and meat.

Social challenges

Eating at restaurants and social events can be difficult while on the keto diet, as it is hard to find keto-friendly options.

Micronutrient deficiencies

The keto diet can lead to nutrient deficiencies, especially if a wide variety of vegetables, fruits, and grains are not consumed.

Health risks

The keto diet is associated with an increased risk of heart disease, kidney problems, constipation, fuzzy thinking, and mood swings. It is also high in saturated fat, which is linked to heart disease. Therefore, it is crucial to consult a doctor and a registered dietitian before attempting the keto diet.

What are the benefits of the keto diet?

The keto diet has been associated with several health benefits. Here are some of the advantages of following a keto diet:

Weight Loss

The keto diet is well-known for promoting weight loss. By restricting carbohydrate intake and increasing fat consumption, the body is forced to use fat as its primary fuel source, leading to a reduction in overall body fat. The process can also help reduce hunger cravings, making it easier to maintain a calorie deficit.

Increased Energy

The keto diet can lead to increased energy levels and a reduction in the typical mid-afternoon energy slumps. This is because fats are a more efficient fuel source for the body and brain than carbohydrates. The stable energy levels throughout the day can improve productivity and overall well-being.

Improved Focus and Mental Clarity

Research suggests that the brain functions more efficiently when using ketones (derived from fat breakdown) as fuel, compared to glucose (derived from carbohydrates). Therefore, the keto diet may enhance focus and mental clarity.

Management of Chronic Illnesses

The keto diet has been used to treat and manage various chronic illnesses, including epilepsy, Alzheimer's disease, autism, brain cancers, type 2 diabetes, and heart disease. By altering the body's fuel source and reducing inflammation, the keto diet can have a positive impact on neurological and metabolic conditions.

Blood Sugar Regulation

The keto diet is effective in managing blood sugar levels, making it beneficial for individuals with type 2 diabetes or those at risk of developing diabetes. By reducing carbohydrate intake, the body's reliance on glucose as the primary fuel source decreases, leading to improved blood sugar control.

Reduced Cravings and Improved Eating Habits

The keto diet can help reduce cravings for sugary and refined carbohydrate foods. Many people report finding it easier to stick to a keto diet after the initial adjustment period, as their taste buds adapt and they become less interested in highly processed, sugary foods.

While the keto diet offers these potential benefits, it is important to note that it may not be suitable for everyone. It is always advisable to consult with a healthcare professional before starting any new diet, especially if you have existing health conditions. Additionally, the keto diet can be challenging to follow due to its restrictive nature, and it may lead to some initial side effects, such as the "keto flu," which includes symptoms like fatigue, headaches, and nausea.
