The ketogenic diet is a low-carb, high-fat diet that has been shown to produce beneficial metabolic changes in the short term, including weight loss and improved health parameters associated with carrying excess weight. However, it's important to note that simply following a ketogenic diet does not guarantee weight loss. Many keto-friendly foods are high in calories, so it's possible to consume too many calories on this diet, especially if portion sizes are too large or if high-calorie snacks are consumed throughout the day. This can lead to weight gain instead of weight loss. Therefore, paying attention to portion size, increasing physical activity, and snacking in moderation are important factors to consider when following a ketogenic diet.

Weight loss
The ketogenic diet is a low-carb, high-fat diet that can lead to weight loss. However, it is important to watch your calorie intake, as many keto-friendly foods are high in calories. For example, avocados, olive oil, full-fat dairy, and nuts are all calorie-dense foods.
If you are not careful, it is possible to consume too many calories on a ketogenic diet by eating large portions or snacking on high-calorie foods throughout the day. To lose weight, you need to create a calorie deficit, which can be achieved by paying attention to portion size, increasing physical activity, and snacking in moderation between meals.
The ketogenic diet has been shown to produce beneficial metabolic changes in the short term, leading to weight loss and improvements in health parameters associated with carrying excess weight, such as insulin resistance, high blood pressure, and elevated cholesterol and triglycerides.
A very low-calorie ketogenic diet (VLCKD) is characterised by a daily caloric intake of less than 800 kcal, low carbohydrate intake (50 g/day), and normoproteic (1-1.5 g of protein/kg of ideal body weight) contents. This type of diet has been shown to induce significant weight loss and improve lipid parameters, blood pressure, glycaemic indices, and insulin sensitivity in patients with obesity and type 2 diabetes mellitus.

Insulin resistance
A ketogenic diet is high in fat and low in carbohydrates. If you don't watch your calorie intake, you're unlikely to lose weight. Many keto-friendly foods, such as avocados, olive oil, full-fat dairy and nuts, are high in calories. It's therefore important not to overdo it. You can still consume too many calories on a ketogenic diet by eating portions that are too large or by snacking on high-calorie foods throughout the day.
A very low-calorie ketogenic diet (VLCKD) is characterised by a daily caloric intake of less than 800 kcal/day, a low carbohydrate intake of less than 50 g/day and a normoproteic content of 1-1.5 g of protein/kg of ideal body weight. This type of diet has been shown to induce significant weight loss and an improvement in insulin sensitivity in patients with obesity and type 2 diabetes mellitus.
Proponents of the ketogenic diet state that if the diet is carefully followed, blood levels of ketones should not reach a harmful level (known as 'ketoacidosis') as the brain will use ketones for fuel, and healthy individuals will typically produce enough insulin to prevent excessive ketones from forming.

A very low-calorie ketogenic diet (VLCKD) is characterised by a daily caloric intake of less than 800 kcal/day, and has been found to induce significant weight loss and improvements in blood pressure, glycaemic indices and insulin sensitivity in patients with obesity and type 2 diabetes mellitus.

However, it is important to note that the number of ketone bodies that accumulate in the blood can vary from person to person, depending on factors such as body fat percentage and resting metabolic rate.

Snacking
To avoid this, it's important to pay attention to portion sizes and not snack excessively throughout the day. Most people find that ketogenic meals and snacks are very filling due to the high fat and protein content. However, if you don't eat enough fat on a keto diet, you may not feel full, which can lead to snacking and consuming more calories than you need.
To prevent this, ensure you're consuming adequate amounts of healthy fats, such as those found in avocados, nuts, and olive oil. These foods can help you feel satisfied between meals and reduce the urge to snack. Additionally, increasing your physical activity can help create the calorie deficit needed to lose weight.
It's worth noting that a very low-calorie ketogenic diet (VLCKD) is characterised by a daily caloric intake of less than 800 calories, along with low carbohydrate and adequate protein intake. This type of diet has been shown to induce significant weight loss and improve health parameters associated with carrying excess weight, such as insulin resistance, high blood pressure, and elevated cholesterol. However, it's important to carefully monitor your calorie intake and ensure you're getting enough nutrients to avoid potential health risks.
