The keto diet is a popular weight loss strategy, but it doesn't work for everyone. The diet involves a high intake of fat, moderate protein, and very few carbohydrates. This puts the body into a metabolic state called ketosis, where it burns fat for energy instead of glucose. However, there are several reasons why some people may not lose weight on the keto diet. These include not achieving ketosis, eating too much protein, consuming too many acceptable carbs, not counting calories, constant snacking, lack of exercise, underlying medical conditions, stress, unrealistic weight loss expectations, and nutrient deficiencies. Additionally, the keto diet can be challenging to sustain due to its restrictive nature and may not be suitable for everyone.
What You'll Learn
Eating too many carbs
Carbs can be tricky to track as they can be hidden in vegetables, sauces, and dressings. It's important to use a macronutrient tracker to monitor your net carbs (total carbs minus fibre and sugar alcohols). Even if you feel like you've drastically reduced your carb intake, you may still be consuming enough carbs for your body to produce energy from glucose, which can slow down your progress.
To achieve and maintain ketosis, it's crucial to be mindful of your total carbohydrate intake. This includes carbs from acceptable keto foods such as nuts and dairy. While these foods are nutrient-dense and high in fat, they still contain carbohydrates. Eating too many of these foods can prevent you from reaching and maintaining ketosis.
Additionally, not all sugar alcohols are created equal. For example, maltitol, a low glycemic index sugar, can still impact blood sugar levels and potentially prevent ketosis. Therefore, it's important to be mindful of your consumption of sugar alcohols as well.
If you're struggling to reduce your carb intake, there are a few tips that can help. First, fill up on low-carb vegetables such as leafy greens, cucumbers, asparagus, and zucchini. These should make up the majority of your plate at every meal. Second, be mindful of higher-carb veggies like broccoli, Brussels sprouts, cabbage, and cauliflower. While they are healthy, they contain more carbs than other vegetables. Third, reserve keto-friendly fruits, such as berries, for occasional desserts. Finally, focus on high-fat proteins. Pair an egg, grass-fed burger, or wild-caught salmon with a green leafy salad and avocado for a filling and keto-friendly meal.

Eating too many calories
Even if you are on a keto diet, it is still possible to overeat. To lose weight, you need to be in a calorie deficit, which means eating fewer calories than you burn. On a keto diet, this can happen naturally due to the satiating effects of fat and protein, but it is not guaranteed.
Fat is calorie-dense, with 9 calories per gram compared to 4 calories per gram for carbohydrates. As such, it is easy to overdo it and consume too many calories, especially since many keto-friendly foods such as avocados, olive oil, full-fat dairy, and nuts are high in calories.
Portion sizes are important to monitor. Even if you are eating the right foods, having too much of them can lead to a calorie surplus. Snacking on high-calorie foods throughout the day can also contribute to this. For example, half a cup of almonds contains over 400 calories.
To get an idea of how many calories you should be consuming, it is best to meet with a dietitian, who can help you determine your ideal calorie intake based on your needs. You can then use a fitness tracker to monitor your calorie intake and ensure it is within the ideal range for weight loss.

Eating too much protein
On the keto diet, protein should make up less than 35% of your diet. This is because your body tends to break down excess protein into amino acids, which can then be turned into sugar. This process is called gluconeogenesis, and it can disrupt ketosis, which is the metabolic state where your body burns fat for energy instead of glucose.
To avoid eating too much protein on the keto diet, it is recommended that the average person consume between 1.5 and 2.0 grams of protein per kilogram of body weight, or about 0.7 to 0.9 grams per pound of body weight. This amount of protein will help maintain muscle mass and improve body composition without causing weight gain.
However, it is important to note that the ideal amount of protein can vary depending on factors such as age, gender, weight, and activity level. For example, older adults looking to remain active and healthy may benefit from a higher protein intake of more than 20% of calories from protein. Similarly, those who are looking to maintain muscle mass while losing weight may need a higher protein intake, as research suggests that diets containing 18%-25% protein can result in greater muscle maintenance when compared to lower protein diets.
In addition, it is worth mentioning that the quality of your protein sources matters as well. While on the keto diet, it is recommended to choose healthy, unprocessed protein sources such as fatty cuts of grass-fed meat, full-fat dairy, nuts, and eggs.
By being mindful of your protein intake and choosing high-quality protein sources, you can help ensure that you are getting the full benefits of the keto diet.

Eating too many acceptable carbs
The keto diet is a low-carb, high-fat, and moderate-protein diet. It is designed to force the body into a state of ketosis, where it burns fat for energy instead of glucose. To achieve ketosis, you need to drastically cut back on your carb consumption, typically to 20-50 grams per day, and sometimes as low as 20 grams.
On the keto diet, several types of carbohydrates are acceptable, including nuts, dairy, and some fruits like berries, avocados, and coconuts. These foods are typically high-fat and nutrient-dense, making them a great addition to a keto diet. However, they also contain carbohydrates, and eating too many of them can prevent you from achieving and maintaining ketosis.
Sugar alcohols are generally a good option for people on the keto diet, as they provide sweetness without increasing net carbs in the body. However, not all sugar alcohols are created equal. For example, maltitol can affect blood sugar levels and may prevent you from entering ketosis.
To achieve and maintain ketosis, it's important to carefully track your carb intake. This can be done by using a macronutrient tracker app, such as MyFitnessPal or Carb Manager, which help you monitor your net carbs. Additionally, planning your meals in advance can help ensure you stay within your daily carb limit.
By limiting your consumption of acceptable carbs and tracking your intake, you can maximize your chances of success on the keto diet and reap the benefits of increased fat burning, reduced blood sugar and insulin levels, and improved mental focus.

Not exercising enough
Exercising is an important part of staying healthy and can be crucial to losing weight on a keto diet. Even if you are in a state of ketosis, you still need to burn more calories than you consume to lose weight. Exercise stimulates the body's metabolism and burns calories. It also helps build muscle, which can give your metabolism a boost by increasing the amount of energy burned at rest.
If you are not exercising enough, you may not be creating a sufficient calorie deficit to lose weight. This is especially important on a keto diet, as the high-fat foods you are eating are very calorie-dense.
To boost your weight loss efforts, try incorporating more physical activity into your lifestyle. You can set a goal of exercising three to four days a week and choose a time that is most convenient for your schedule. To stay motivated, you can prepare a workout bag in advance or lay out your exercise clothes before bed.
In addition to helping with weight loss, regular exercise provides numerous health benefits. It lowers your risk of chronic conditions such as heart disease, diabetes, depression, anxiety, and obesity. It also improves your overall health and well-being.
By increasing your physical activity levels, you can maximize your chances of weight loss success on a keto diet.
