The ketogenic diet is a very low-carb, high-fat diet that has been used as a therapeutic nutrition plan for over 100 years. While it was originally introduced to treat children with epilepsy, today it is primarily used to promote weight loss and manage blood sugar levels. The diet involves restricting your body of carbohydrates and increasing calories from fat, which helps your body switch its main fuel source from glucose to ketones. This metabolic state is called ketosis.
The time it takes to enter ketosis varies from person to person, but it generally takes 2-4 days if you eat 20-50 grams of carbs per day. However, some people may find it takes a week or longer, especially if they are coming from a high-carb diet. During this transition, some people experience symptoms like headaches, fatigue, nausea, bad breath, and increased thirst, sometimes known as the keto flu.
While the keto diet can be an effective way to lose weight, it is not for everyone. It is important to consult your doctor before starting this diet, especially if you have a liver or kidney condition. Additionally, the long-term health implications of the keto diet are still unknown, and there are concerns about potential side effects such as fat buildup in the liver, kidney stones, inadequate protein levels, and vitamin deficiency.
For women in their 30s, weight loss can be more challenging due to hormonal changes, slower metabolism, and muscle mass loss associated with aging. However, the keto diet may be an effective tool for weight loss in this age group, provided it is done safely and under medical supervision. It is important to note that the research on keto for women is still emerging, and most studies have been conducted on male participants.
To increase the chances of success on the keto diet, women in their 30s may need to make some adjustments. For example, a gradual reduction in carb intake over a few weeks may be more effective than a drastic cut. Additionally, intermittent fasting, resistance training, and tracking food intake can help with weight loss. It is also crucial to ensure adequate calorie intake and not restrict calories too much, as this can be unhealthy.
In summary, while the keto diet may be a fast and effective way to lose weight for women in their 30s, it should be approached with caution and under medical guidance. It is important to make adjustments as needed and ensure adequate nutrient intake to support overall health.

What You'll Learn
The keto diet can help with weight loss and managing blood sugar levels
The keto diet is a high-fat, low-carbohydrate diet. It was initially developed in the 1920s as a treatment for epilepsy, but it has since been studied for its effects on type 2 diabetes and weight loss.
The keto diet can help with weight loss in several ways. Firstly, by restricting carbohydrates, the body is forced to use up its glycogen stores for energy and eventually switch to burning fat for fuel. This process, known as ketosis, can lead to rapid weight loss, with individuals on a keto diet potentially losing up to 10 pounds in 2 weeks. Additionally, the keto diet can reduce calorie intake, as carbohydrate-rich foods often contribute a large share of calories.
However, it is important to note that the keto diet is not a sustainable long-term solution for weight loss. It can be challenging to adhere to due to its restrictive nature, and weight loss may slow down or plateau after the initial rapid loss.
The keto diet can also be beneficial for managing blood sugar levels, especially for individuals with type 2 diabetes. By limiting carbohydrates, the keto diet helps to minimise fluctuations in blood sugar levels and improve overall blood sugar control. This is because carbohydrates are broken down into glucose, which raises blood sugar levels. Therefore, reducing carbohydrate intake can lead to lower blood sugar levels and a reduced need for insulin.
However, it is crucial to consult a healthcare professional before starting the keto diet, especially for individuals with diabetes, as there are potential risks and side effects associated with the diet. Additionally, the long-term health implications of the keto diet are still unknown, and more research is needed to fully understand its consequences.

How to Tell Whether You're in Ketosis
As your body transitions into ketosis, you may experience several symptoms, including headaches, fatigue, nausea, bad breath, and increased thirst. These symptoms are sometimes known as the "keto flu." While these symptoms may indicate that your body is transitioning, the best way to tell whether you're in ketosis is to test your body's ketone levels.
Ways to Measure Ketone Levels
Testing your body's ketone levels is the best way to know whether you're in ketosis. There are three types of ketones: acetoacetate, acetone, and beta-hydroxybutyrate. These can be measured through your urine, breath, and blood, respectively.
Multiple factors, including age, metabolism, exercise level, and current carb, protein, and fat intake, can affect how long it takes to enter ketosis. Taking longer to enter ketosis is usually due to unintentionally eating more carbs than recommended for a ketogenic diet. Eating too many carbs can stop your body from producing ketones.

The keto diet is not recommended for people with liver and kidney conditions
The keto diet is a low-carb, high-fat diet that has been around since the 1920s. It was initially introduced as a therapeutic nutrition plan to treat children with epilepsy. Today, it is primarily used to promote weight loss and manage blood sugar levels.
The keto diet involves drastically reducing your intake of carbohydrates to under 50 grams per day, which forces your body to use up its glycogen stores for energy and, eventually, switch to using ketones as fuel. This metabolic state, known as ketosis, typically takes 2-4 days to achieve, but it can take some people a week or longer.
While the keto diet can lead to rapid weight loss, it is not recommended for everyone. In particular, people with liver and kidney conditions are advised to avoid the keto diet due to the following risks:
Liver Problems
The keto diet requires the body to metabolise a large amount of fat, which can overload the liver and make any existing liver conditions worse. In addition, the high intake of saturated fats encouraged by the keto diet has been linked to an increased risk of heart disease.
Kidney Problems
The kidneys play a crucial role in metabolising protein, and the high protein content of the keto diet may overload them. The current recommended intake for protein is 46 grams per day for women and 56 grams for men, but the keto diet often exceeds this amount.
Nutrient Deficiency
The keto diet restricts fruits and vegetables, which are rich in essential vitamins and minerals. This can lead to deficiencies in micronutrients such as selenium, magnesium, phosphorus, and vitamins B and C.
Constipation
The keto diet is low in fibrous foods like grains and legumes, which can lead to constipation.
Fuzzy Thinking and Mood Swings
The brain functions best when it has a steady supply of sugar from healthy carbohydrates. The low-carb nature of the keto diet may cause confusion and irritability.
Kidney Stones
Kidney stones are a well-noted potential side effect of the keto diet, especially when it includes a high intake of animal proteins. This is because a high intake of animal proteins increases the acidity of urine and raises calcium and uric acid levels, which can lead to the formation of kidney stones.
In conclusion, while the keto diet may be an effective way to lose weight, it is not suitable for everyone. People with liver and kidney conditions, in particular, should avoid the keto diet due to the potential risks outlined above. It is always advisable to consult a doctor and a registered dietitian before starting any new diet, especially one as restrictive as keto.

The keto diet can be challenging to stick to while travelling
The ketogenic diet is a high-fat, low-carb diet that has gained popularity in recent years. It can be challenging to stick to while travelling due to limited food options, the temptation to indulge in new foods and drinks, disruptions to your normal routine, and difficulty in tracking your macros and preparing meals. However, with some planning and flexibility, you can stay on track with your keto diet even when you're on the go. Here are some tips to help you stick to your keto diet while travelling:
Plan ahead
Do some research on keto-friendly restaurants and grocery stores at your destination. If you're flying, don't rely on airline food. Instead, bring your own low-carb meals and snacks, such as meat, eggs, fish, nuts, jerky, and cheese crisps. If you're driving, you can bring a cooler with more options.
Book accommodation with kitchen facilities
Consider staying in a hotel room with a kitchenette or an apartment where you can prepare your own meals. Most major travel sites offer an option to search for self-catered accommodation. You can also rent an Airbnb with a full kitchen, which will make it easier to store and prepare your meals.
Tell your server about your keto diet
Keto is a well-known diet these days, and many restaurants cater to keto customers. When dining out, don't be shy about mentioning that you're on a keto diet. The server will be able to steer you towards suitable dishes, and you can also ask for modifications to make dishes more keto-friendly, such as swapping out buns for lettuce leaves or asking for sauces and dressings on the side.
Shop for groceries
Stock up on keto-friendly groceries, especially if you have access to a kitchen. Buy staple keto foods such as avocados, sardines in extra virgin oil, nut butters, cheese, and olives. If you're in a hot climate, MCT powder can be a useful addition to your coffee instead of butter or oil.
Stay active
Exercising while travelling will help you stay in ketosis. Start your day with a run, take advantage of any fitness facilities at your hotel, or try bodyweight exercises like squats, push-ups, and lunges in your room.
Try intermittent fasting
Intermittent fasting pairs well with the keto diet. If you're fat-adapted, you can access body fat for energy, making fasting easier. This can be especially useful when travelling, as you may not always have keto-friendly food options readily available.
Stay hydrated
Drinking plenty of water is important on the keto diet, as it can help prevent dehydration and reduce cravings for high-carb foods. Always carry a reusable water bottle with you, and refill it frequently. Unsweetened tea and black coffee are also good options.
Be cautious with alcohol
Alcoholic drinks can be high in carbs, so be mindful of your consumption and choose low-carb options such as pure forms of alcohol like whiskey, gin, tequila, rum, and vodka, combined with low-carb mixers.

The keto diet can cause constipation
The keto diet is a very high-fat, very low-carb, and moderate-protein eating pattern. This way of eating induces a phenomenon called ketosis, where the body burns fat instead of glucose for energy. While the keto diet may help burn fat, there can also be side effects, many of which are related to the gastrointestinal (GI) tract reacting to the absence of carbs. One such side effect is constipation.
Causes of Constipation on the Keto Diet
The keto diet drastically reduces carbohydrate intake, which can lead to digestive issues like constipation. Carbohydrates like fruits and whole grains are common sources of fiber in the diet, and transitioning to a low-carb diet can result in a lack of fiber. Additionally, some people may have difficulty adjusting to the very high-fat content of the diet, which can also cause GI upset.
The keto diet typically restricts carbohydrate intake to 20-50 grams per day, which is significantly lower than the recommended intake of 225-325 grams based on a 2,000-calorie diet. This restriction makes it challenging to consume enough fiber, which is essential for maintaining healthy bowel movements.
Another reason for constipation on the keto diet is a reduced intake of low-carb, high-fiber foods. It is important to ensure that the carbohydrates consumed on the keto diet are of the right kind, such as nutritious, high-fiber, keto-friendly foods like non-starchy vegetables and limited amounts of berries.
Furthermore, individuals following the keto diet may consume more dairy, which can be a common cause of constipation due to the presence of lactose, a type of sugar in milk that can be difficult to digest.
Reduced water intake can also contribute to constipation on the keto diet. With a lower consumption of fruits and vegetables, water intake may decrease without realizing it. Additionally, a sudden drop in carb intake can lead to dehydration and an imbalance of electrolytes.
Treating and Preventing Constipation on the Keto Diet
To treat and prevent constipation on the keto diet, it is recommended to:
- Increase the consumption of high-quality fats, aiming for 55-60% of daily calories from healthy fats like nuts, nut butter, extra virgin olive oil, avocado oil, avocados, meats, eggs, and fatty fish.
- Add more fiber-rich, low-carb foods to the diet, such as leafy greens, broccoli, nuts, seeds, and berries.
- Engage in regular physical activity, as exercise can help deplete the body's glycogen stores, encouraging the production of ketones.
- Ensure adequate water intake, as sufficient hydration is essential for the body to effectively rid itself of waste.
- Gradually introduce the keto diet to allow the digestive system to adjust. Starting with a higher daily carb intake and slowly reducing it can make it easier to stick to the diet and reduce side effects.
- Choose whole foods over processed meals and fast food, as they are typically low in fiber and can put extra stress on the GI system.
- Consume enough keto-friendly, high-fiber foods, such as non-starchy vegetables, including greens, broccoli, asparagus, and cauliflower.
