A 600-calorie diet is an extreme calorie restriction diet that is often unsustainable and unsafe. It is considered a rapid weight loss diet, which is generally unsafe for children, teens, pregnant women, and older adults. However, in certain cases, such as clinical settings or treating obesity, very low-calorie diets (VLCDs) can be safe under proper medical supervision. The 5:2 diet is an example of an intermittent fasting regime that restricts calories to 500-600 per day for two days a week, but it may not be suitable for everyone. While a 600-calorie diet can lead to weight loss, it can also have physical, hormonal, and mental health risks.

What You'll Learn
The 5:2 diet
A 600-calorie diet is typically associated with rapid weight loss and is generally not safe for everyone. It is usually recommended for adults with obesity and related health issues. Intermittent fasting is a popular weight loss tool that involves eating normally on certain days and fasting on others. The 5:2 diet is an example of an intermittent fasting regime.
On fasting days, it is important to focus on nutritious, high-fibre, and high-protein foods to promote satiety. Soups are a great option, as they can make you feel fuller. There are no specific rules for eating on fasting days, so it is important to experiment and find what works best for you.
While the 5:2 diet may be effective for some people, it is not suitable for everyone. It is important to consult with a healthcare provider or registered dietitian before starting this or any other diet plan, especially if you have an underlying health condition.

Potential health risks
A 600-calorie diet is considered a very low-calorie diet (VLCD), which typically ranges from 800 to 1200 calories per day. While VLCDs can be effective for weight loss, they are not without potential health risks. Here are some of the possible dangers associated with a 600-calorie diet:
- Nutritional Deficiencies: Restricting your calorie intake to 600 calories per day may not provide sufficient nutrients, such as essential vitamins and minerals. This can lead to nutritional deficiencies, which can have adverse effects on your health. For example, a lack of certain vitamins and minerals can cause fatigue, weakened immune system, and increased risk of disease.
- Rapid Weight Loss: While rapid weight loss may be appealing, it can be unsafe and is generally not recommended for the long term. Losing weight too quickly can lead to health issues such as gallstones, electrolyte imbalances, and a higher risk of muscle loss. Additionally, rapid weight loss is often difficult to sustain, and individuals may regain the weight once they return to their usual eating habits.
- Health Complications: A 600-calorie diet may not be suitable for everyone and can potentially lead to health complications, especially for individuals with certain medical conditions. It is crucial to consult a healthcare professional before starting such an extreme diet to ensure it is safe for your specific circumstances. For example, it may not be advisable for individuals with diabetes, heart disease, or other health issues.
- Physical, Hormonal, and Mental Risks: A 600-calorie diet is a significant deficit in energy intake, which can have wide-ranging impacts on your body. It may lead to physical issues such as fatigue, dizziness, and reduced physical performance. Hormonal imbalances may also occur, affecting reproductive health and overall well-being. Additionally, extreme calorie restriction can take a toll on mental health, potentially leading to increased stress, anxiety, and even depression.
- Sustainability and Rebound Effects: VLCDs are typically not recommended for long-term weight loss as they are challenging to sustain. Once an individual returns to a normal diet, there is a risk of regaining the weight, known as the "rebound effect." This can lead to a cycle of yo-yo dieting, which is unhealthy and may cause further harm to both physical and mental health.
While a 600-calorie diet may be suitable as a short-term solution or under medical supervision, it is generally not recommended as a long-term weight loss strategy due to the potential health risks outlined above. It is always advisable to consult with a healthcare professional or a dietician before starting any extreme diet to ensure it is safe and appropriate for your individual needs.

Weight loss
A 600-calorie diet is a form of intermittent fasting that involves eating only 600 calories per day. This is a very low-calorie diet, with the typical nutritional value of low-calorie diets ranging from 1200 to 1500 calories. The 600-calorie diet is often referred to as the 5:2 diet, which involves eating normally for five days and restricting calorie intake to 500-600 calories on the remaining two days.
This type of diet can be effective for weight loss, as it creates an energy deficit, causing the body to use its reserves and resulting in the loss of body mass and body fat. While this diet can lead to rapid weight loss, it is not without risks. A very low-calorie diet can lead to physical, hormonal, and mental health risks, and it is generally not enough for a healthy adult female. It is important to note that losing weight quickly and eating very low-calorie diets are dangerous and should be done only under the supervision of a doctor and nutritionist.
Some people may experience minor side effects such as fatigue, constipation, nausea, and diarrhea, especially when following a very low-calorie diet for an extended period. In addition, gallstones are the most common serious side effect of very low-calorie diets, occurring more frequently during rapid weight loss. When the body experiences a calorie deficit, it breaks down fat for energy, causing the liver to secrete more cholesterol. This increase in cholesterol, combined with bile, can lead to the formation of gallstones.
Despite the risks, a 600-calorie diet may be appropriate for short-term weight loss or as part of medical treatment under the supervision of healthcare professionals. Studies have shown that very low-calorie diets can be safe and effective for treating obesity in individuals with a body mass index (BMI) of at least 30 kg/m^2. Losing as little as 5% of body weight can improve medical conditions such as diabetes, high blood pressure, and high cholesterol. However, in the long run, very low-calorie diets are not more effective than more modest diets.

Before embarking on this diet, it is important to consult a healthcare professional to ensure it is safe for you. It is also crucial to focus on nutrient density and monitor your health, as rapid weight loss can lead to muscle loss, nutrient deficiencies, and other health issues.
When creating meal plans for the 600-calorie diet, it is essential to plan your meals to maximise nutritional value. You can opt for one bigger meal or several smaller portions throughout the day. Here is a sample meal plan with daily averages of 595 calories, 45g protein, 21g fat, and 62g carbs:
