The ketogenic diet is a low-carb, high-fat, and moderate-protein eating style that has become popular for weight loss and health improvement. However, it is not always effective, and there are several reasons why someone may not lose weight on a keto diet.
Firstly, it is crucial to understand that achieving ketosis, a metabolic state where the body burns fat for energy instead of glucose, is essential for weight loss on a keto diet. This requires a drastic reduction in carbohydrate intake, typically to 20-50 grams per day, and close monitoring of macronutrient consumption.
Even when in ketosis, weight loss may be hindered by factors such as consuming too many calories, frequent snacking, insufficient exercise, stress, inadequate sleep, underlying medical conditions, and consuming too much dairy or unhealthy foods.
Additionally, the quality of fats and the accuracy of macronutrient tracking are important considerations. It is also worth noting that weight loss is not always linear, and there may be fluctuations or plateaus.
In summary, while the keto diet can be effective for weight loss, it requires careful planning, monitoring, and addressing of any underlying issues to ensure success.

What You'll Learn
Eating too many carbs
Carbs can be sneaky and are often hidden in vegetables, sauces, dressings, and even some keto-friendly foods. For example, nuts are high in carbs and calories and can be easy to overeat. Dairy products are also high in carbs and can affect your metabolism, hindering weight loss. Even some healthy sugars, like coconut sugar or raw cane sugar, are high in carbs and can prevent your body from adapting to the low-carb diet.
To avoid eating too many carbs, it's important to track your macronutrient intake. Use a macronutrient tracker to monitor your net carbs (total carbs minus fiber minus sugar alcohols). Aim for no more than 20-50 grams of net carbs per day. Fill up on low-carb vegetables like leafy greens, cucumbers, asparagus, and zucchini, and be mindful of higher-carb veggies like broccoli and cabbage.
In addition to tracking your carbs, make sure you're not overeating in general. Even on a keto diet, it's possible to consume more calories than you burn, leading to weight gain. Half a cup of almonds, for example, contains over 400 calories. Track your calorie intake using fitness apps or trackers to ensure you're consuming within an ideal range for weight loss.
Finally, be cautious of processed and packaged keto-friendly foods. These may contain hidden carbs and can provide extra calories that hinder weight loss. Stick to unprocessed, whole foods like full-fat dairy, eggs, fish, meat, and healthy fats like avocado and olive oil.

Eating too many calories
Even when following a keto diet, it is still possible to consume too many calories, which can prevent weight loss. This is because, to lose weight, you need to be in a calorie deficit, meaning you are consuming fewer calories than you burn.
On a keto diet, it is easy to overindulge in high-calorie foods such as nuts, avocados, olive oil, full-fat dairy, and other keto-friendly snacks. For example, half a cup of almonds contains over 400 calories. Therefore, it is important to pay attention to portion sizes and not snack too frequently throughout the day.
To ensure you are in a calorie deficit, you can use fitness trackers to monitor your calorie intake and expenditure. Additionally, creating a food journal can help you identify any problem areas in your diet.

Eating too much protein
The body's metabolic process, called gluconeogenesis, is triggered when there are not enough carbohydrates in the body. In this process, the body produces glucose from non-carbohydrate sources, such as amino acids, as it needs a small amount of glucose to function properly. As a result, if there is an excess of protein, the body will opt to use amino acids to produce glucose instead of breaking down fat into ketones. Thus, a person will not enter ketosis and will remain in a state of burning sugar for energy.
There are a few signs that indicate a person is consuming too much protein on a keto diet. One sign is if a person's breath smells like ammonia. This is because ammonia is produced when the body digests and breaks down protein, and excess protein intake can lead to increased ammonia production, which is then exhaled. Another sign is experiencing flu-like symptoms, such as low energy, irritability, headaches, muscle cramps, and digestive issues. This is due to shifts in electrolyte levels and hydration, similar to the symptoms experienced when first starting a keto diet, known as the "keto flu."
To ensure they are getting the right amount of protein, it is recommended that individuals calculate their protein intake based on their body composition, activity levels, and goals. Generally, individuals should aim for about 20% of their daily calories to come from protein, which is about 1 gram of protein per kilogram of body weight. Tracking food intake through an app or testing ketone levels with at-home strips can also help individuals monitor their protein intake and ensure they are staying within the optimal range for ketosis.

Not exercising enough
Exercise is an important part of staying healthy and can be especially important when following a keto diet. It stimulates the body's metabolism, burning calories and helping to create a calorie deficit, which is necessary for weight loss.
If you are not losing weight on a keto diet, it may be because you are not exercising enough. To lose weight, you need to burn more calories than you consume, and exercise is a crucial part of this.
The keto diet is a high-fat diet, and it can be easy to consume more calories than you realise. Even if you are in a state of ketosis, where your body is burning fat for energy instead of glucose, you may still need to exercise to create a calorie deficit and lose weight.
Exercise also has other health benefits. It helps you build muscle, which boosts your metabolism by increasing the amount of energy burned at rest. This means you will burn more calories even when you are not exercising.
In addition, exercise lowers your risk of chronic conditions such as heart disease, diabetes, depression, anxiety and obesity. It is an important part of a healthy lifestyle, and can help to improve your overall health and well-being.
If you are not losing weight on a keto diet, try incorporating more physical activity into your routine. This could include cardio, such as interval training, or muscle-building exercises such as weightlifting. Creating a workout schedule and sticking to it can help you develop a healthy exercise habit.
Remember, weight loss is not always linear, and there may be other factors at play if you are not losing weight on a keto diet. However, ensuring you are getting enough physical activity is an important step in reaching your weight loss goals.

Not managing stress
When you start a keto diet, your body goes through a lot of changes and adaptations. Restricting carbohydrates can initially be interpreted by the body as a form of acute stress, as it may seem like there is a food shortage. This can cause a rise in cortisol levels, which is the "stress" hormone. However, this doesn't mean that being on a keto diet will cause chronic stress.
In fact, a well-constructed ketogenic diet can naturally decrease stress, especially when you focus on eating certain stress-fighting keto foods. For example, a 2021 study found that obese men in their 50s and 60s experienced a significant decrease in their salivary cortisol levels after 8 weeks on a calorie-restricted keto diet. Additionally, a study published in the journal *Metabolism* found that after 6 weeks on a keto diet, there was no change in cortisol levels, while fat mass significantly decreased.
It's important to note that the stress response to a keto diet may depend on age, gender, and various other factors. For instance, a study published in the *Journal of Physiology and Pharmacology* found that after 3 days on a keto diet, participants had an increase in cortisol, adrenaline, and noradrenaline levels. However, this was an acute reaction, and longer-term studies have shown that stress levels can decrease once the body is thoroughly in ketosis and adapted to the diet.
To manage stress while on a keto diet, it is recommended to focus on eating high-quality, keto-friendly foods such as good fats (avocado, coconut oil, grass-fed butter), moderate amounts of protein (grass-fed beef, wild salmon, pasture-raised eggs), and high-fiber, low-carb plant foods (non-starchy veggies, nuts, seeds). Additionally, including stress-fighting foods such as avocados, berries, dark chocolate, and fermented foods can help to reduce stress levels.
While a keto diet has the potential to reduce stress, it is important to be mindful of symptoms and make adjustments as needed. If you feel that the keto diet is contributing to mental health challenges, consider increasing your carbohydrate intake or seeking professional help.

Frequently asked questions
There are several reasons why you might not be losing weight on keto. Some common reasons include eating too many carbs, not achieving ketosis, eating too many calories, not exercising enough, and not getting enough sleep.
There are a few ways to test for ketosis. You can use urine strips, ketone breath meters, or blood meters to measure ketone levels in your body. Alternatively, look for signs such as strong-smelling breath, increased energy and focus, fewer cravings, and keto flu symptoms.
Ketosis is a metabolic state in which your body burns fat for energy instead of glucose. This happens when you drastically reduce your carbohydrate intake, and your body doesn't have enough stored carbs for fuel.
On keto, you should restrict your carb intake to about 20-50 grams per day. However, the exact amount may vary depending on your body and activity level.
To achieve ketosis, it's important to minimize your carbohydrate intake. Make sure to read labels and track your net carb intake, as carbs can be hidden in vegetables, sauces, and dressings. Additionally, consider using MCT oil, which can help kick-start ketosis.
