The keto diet is a high-fat, low-carbohydrate, and moderate-protein diet. It is advertised as a weight-loss wonder, but it is actually a medical diet that comes with serious risks. It is important to note that the keto diet is not about eating unlimited amounts of food; it is about drastically reducing your carbohydrate intake and increasing your fat intake. Eating too many calories, even if they are from keto-approved foods, can hinder weight loss. To maximise weight loss on a ketogenic diet, it is important to pay attention to portion sizes, increase physical activity, and consume whole, nutritious, low-carb foods.

What You'll Learn
Eating too many calories
On the keto diet, it is possible to consume too many calories, especially if portion sizes are not monitored. Eating large portions or snacking on high-calorie foods throughout the day can quickly lead to an excess of calories, hindering weight loss efforts. To avoid this, pay attention to portion sizes and choose nutritious, whole foods that are recommended for the keto diet, such as fish, meat, poultry, non-starchy vegetables, healthy fats, and full-fat dairy products.
Snacking between meals can also contribute to excessive calorie intake. Keto-friendly snack bars, desserts, and packaged foods often provide extra calories and lack essential nutrients. Instead, opt for nutrient-dense, unprocessed foods, and if snacking is necessary, do so in moderation. Additionally, be mindful of your intake of convenience foods like hot dogs and fast food, as they tend to be high in calories and low in nutritional value.
It is important to note that the keto diet is not just about calorie counting but also about carbohydrate restriction. To enter and maintain ketosis, a state where your body burns fat for energy instead of glucose, you must drastically reduce your carbohydrate intake. However, this does not mean unlimited consumption of fatty foods. Even on the keto diet, excessive calorie intake can occur, leading to weight loss plateaus or even weight gain. Therefore, it is crucial to strike a balance between reducing carbohydrates and maintaining a healthy calorie intake.
In conclusion, while the keto diet may be an effective tool for weight loss, it is important to remember that eating too many calories can sabotage your efforts. To maximize weight loss on keto, focus on portion control, choose nutritious whole foods, limit snacking, and stay physically active. By creating a calorie deficit and adhering to the recommended macronutrient ranges, you can increase your chances of success on the keto diet and improve your overall health.

Lack of activity
Lack of physical activity can negatively impact weight loss when on a keto diet. Engaging in physical activity not only burns calories but also helps build muscle, which boosts metabolism by increasing the amount of energy burned at rest.
To lose weight, it is critical to create a calorie deficit, which can be achieved by reducing calorie intake or expending more calories through physical activity. The keto diet is high in fat and calories, so it is important not to overindulge. Many keto-friendly foods, such as avocados, olive oil, full-fat dairy, and nuts, are calorie-dense, and it is easy to consume too many calories if portion sizes are not monitored.
Additionally, the keto diet is associated with fatigue, especially when starting out. This is because the body switches from using glucose as its primary fuel source to burning fat for energy, which requires adjustments in the body. As a result, some people may feel more tired and less motivated to engage in physical activity.
To combat this, it is important to be mindful of portion sizes and to increase physical activity levels gradually. Creating a workout schedule and sticking to it can help establish a healthy exercise habit. Aim for three to four days a week and choose a convenient time to exercise. Staying active and consuming a balanced keto diet with whole, nutritious, low-carb foods can help maximize weight loss and improve overall health.

Not eating enough vegetables
Vegetables are a vital part of a healthy diet, and they are also key components of a successful ketogenic diet. In fact, people on a keto diet eat even more vegetables than those on an average diet. Vegetables form the basis of every meal, replacing potatoes, rice, and pasta as "side dishes" for satiety.
However, not all vegetables are suitable for a keto diet. Some vegetables contain too many carbs to be suitable. Starchy vegetables, such as peas, potatoes, and legumes, are considered some of the least keto-friendly vegetables and should be avoided. Root vegetables, such as onions, carrots, and beets, are also higher in carbs and should be consumed in moderation.
So, which vegetables should you eat on a keto diet? Above-ground vegetables are generally lower in carbs and a great option. Leafy green vegetables, such as lettuce, spinach, kale, arugula, Swiss chard, and other greens, are good ketogenic options. They are low in carbs and provide the body with important micronutrients, such as vitamins A, C, and K, and iron. They also help fight inflammation and provide antioxidants and fiber.
Other keto-friendly vegetables include zucchini, cucumber, avocado, tomatoes, cabbage, broccoli, cauliflower, mushrooms, and eggplant. These vegetables are low in carbs and can be prepared in a variety of ways, such as raw, grilled, roasted, or sautéed.
It is important to note that the keto diet may not be suitable for everyone, and it is always recommended to consult with a doctor or registered dietitian before starting any restrictive diet.

Consuming too much meat
The keto diet is a low-carb, high-protein, and high-fat diet. It is advertised as a weight-loss solution, but it is actually a medical diet that comes with serious risks. It is a controversial diet, with many doctors and nutritionists considering it harmful to health.
Meat is important for keto, as it is a key source of protein and nutrients like vitamin B12. However, it is not an all-meat diet. Eating too much meat can increase your risk of health problems. Cooking meat at high temperatures can produce harmful compounds that could increase your risk of cancer. Processed meat takes the risk even further, as it contains trans fats, which are linked to an increased risk of health problems.
To avoid these risks, it is important to prioritize monounsaturated fats from foods like avocados, fish, nuts, and seeds, and unprocessed oils like olive oil or coconut oil. It is also important to eat meat in moderation, and to supplement your diet with other sources of protein such as eggs, dairy, and nuts.
In addition, it is important to be mindful of portion sizes and to increase physical activity when following the keto diet. This will help create the calorie deficit needed to lose weight.

Not getting enough fibre
The keto diet is a low-carb, high-protein eating plan that has been adopted by many looking to lose weight and improve their health. However, it is often criticised for lacking fibre, which can lead to constipation and other digestive issues.
Dana Elia, RDN, an integrative and functional medicine dietitian, notes that dietitians frequently see patients who complain of constipation when they go keto. This is because most fibre-rich foods, such as whole grains, fruits, and legumes, are also high in carbohydrates, which are restricted on the keto diet. As a result, it can be challenging to get enough fibre on the keto diet, which is essential for digestive health.
High-fat diets, such as keto, can slow digestion and decrease GI motility, so it is crucial to ensure adequate fibre intake. The USDA's 2020-2025 Dietary Guidelines for Americans recommend a daily fibre intake of 28 to 34 grams, depending on age and sex. While following the keto diet, it is essential to be diligent and choose high-fibre, low-carb foods to meet these recommendations. Examples of keto-friendly, high-fibre foods include:
- Raspberries: A half-cup of fresh raspberries offers 4 grams of fibre and 3.3 grams of net carbs.
- Avocado: A medium-sized avocado provides 9 grams of fibre without any sugar.
- Asparagus: Asparagus, in both its fresh and cooked forms, is a good source of dietary fibre.
- Coconut: A small piece of coconut meat offers about 3 grams of net carbs and 4 grams of fibre.
- Artichokes: One canned artichoke heart offers 1.7 grams of fibre and less than 1.9 grams of net carbs.
- Cauliflower: A 1-cup serving of this low-carb veggie has about 3 grams of net carbs and 2 grams of fibre.
- Brussels sprouts: Each cup of boiled, broiled, or pan-fried Brussels sprouts has 4 grams of fibre.
- Pistachios: When compared to other nuts, pistachios are richer in fibre, with about 10% of their weight coming from insoluble fibre.
- Flaxseed: Each tablespoon of flaxseed has about 1.9 grams of fibre and contains virtually no digestible carbohydrates.
If you find it challenging to meet your fibre goals through diet alone while on keto, you can consider adding a fibre supplement like Metamucil to ensure you reach the recommended daily intake. It is important to talk to your healthcare provider if you have any questions or concerns about your diet and fibre intake.
