Eating only 600 calories a day can have severe and long-lasting effects on your overall health and well-being. While it may seem like a quick fix for weight loss, drastically reducing your daily caloric intake can lead to malnutrition, fatigue, and a host of other health problems. In this article, we’ll explore the risks and consequences of consuming only 600 calories a day and provide guidance on how to maintain a healthy weight without sacrificing your overall health.
What is a Calorie and Why Do We Need Them?
Before we dive into the effects of eating only 600 calories a day, it’s essential to understand what calories are and why our bodies need them. A calorie is a unit of energy that our bodies use to function, grow, and repair tissues. We get calories from the food we eat, and our bodies use them to power our daily activities, from breathing and digestion to exercise and physical activity.
The recommended daily caloric intake varies depending on factors such as age, sex, weight, height, and activity level. Generally, the recommended daily caloric intake is:
- 1,600-2,000 calories for sedentary women
- 1,900-2,400 calories for moderately active women
- 2,000-2,400 calories for sedentary men
- 2,200-2,800 calories for moderately active men
What Happens When You Eat Only 600 Calories a Day?
Eating only 600 calories a day is considered a very low-calorie diet (VLCD). When you drastically reduce your caloric intake, your body is forced to adapt by using stored energy sources, such as fat and muscle mass, to function. While this may lead to weight loss in the short-term, it can have severe and long-lasting effects on your overall health.
Some of the effects of eating only 600 calories a day include:
- Malnutrition: When you don’t consume enough calories, you’re also not getting enough essential nutrients, such as vitamins, minerals, and protein. This can lead to malnutrition, which can cause a range of health problems, from fatigue and weakness to impaired immune function.
- Fatigue and Weakness: When your body doesn’t have enough energy to function, you may feel tired, weak, and lacking in energy. This can make it difficult to perform daily activities, exercise, or even get out of bed.
- Loss of Muscle Mass: When your body doesn’t have enough energy to function, it may start to break down muscle mass to use for energy. This can lead to a loss of muscle mass, which can slow down your metabolism and make it harder to lose weight in the long-term.
- Slowed Metabolism: When you drastically reduce your caloric intake, your metabolism may slow down to conserve energy. This can make it harder to lose weight in the long-term and may even lead to weight gain once you start eating normally again.
- Hormonal Imbalance: Eating only 600 calories a day can disrupt hormone levels, including a decrease in leptin, which can lead to an increase in hunger and a slower metabolism.
- Reduced Immune Function: Malnutrition and a lack of essential nutrients can impair immune function, making you more susceptible to illness and infection.
- Bad Breath, Hair Loss, and Skin Problems: Malnutrition and a lack of essential nutrients can also cause bad breath, hair loss, and skin problems, such as acne and dry skin.
The Risks of Eating Only 600 Calories a Day
Eating only 600 calories a day can have severe and long-lasting effects on your overall health. Some of the risks include:
Short-Term Risks
- Dehydration: When you don’t consume enough calories, you may not be getting enough fluids, which can lead to dehydration.
- Electrolyte Imbalance: Malnutrition and a lack of essential nutrients can lead to an electrolyte imbalance, which can cause muscle cramps, weakness, and heart arrhythmias.
- Low Blood Sugar: Eating only 600 calories a day can cause low blood sugar, which can lead to dizziness, weakness, and fainting.
Long-Term Risks
- Organ Damage: Malnutrition and a lack of essential nutrients can cause damage to organs, such as the heart, liver, and kidneys.
- Osteoporosis: A lack of essential nutrients, such as calcium and vitamin D, can lead to osteoporosis, which can increase the risk of fractures and osteopenia.
- Anemia: Malnutrition and a lack of essential nutrients can cause anemia, which can lead to fatigue, weakness, and shortness of breath.
Who Should Not Eat Only 600 Calories a Day
Eating only 600 calories a day is not suitable for everyone, particularly:
- Pregnant or Breastfeeding Women: Pregnant or breastfeeding women need more calories and essential nutrients to support the growth and development of their baby.

Seek Professional Help
If you’re struggling to lose weight or need guidance on how to maintain a healthy weight, consider seeking professional help from a registered dietitian or a healthcare professional. They can help you develop a personalized weight loss plan that takes into account your unique needs and health goals.
In conclusion, eating only 600 calories a day is not a sustainable or healthy way to lose weight. While it may lead to weight loss in the short-term, it can have severe and long-lasting effects on your overall health. By focusing on healthy eating habits, regular physical activity, and lifestyle changes, you can achieve a healthy weight and maintain it for the long-term.
What happens to my body when I eat only 600 calories a day?
Eating only 600 calories a day can lead to a range of physical changes in the body. Initially, the body will use stored glycogen for energy, but once these stores are depleted, it will begin to break down fat for fuel. This can result in weight loss, but it can also lead to a loss of muscle mass and a decrease in metabolism. As the body adapts to the reduced calorie intake, it may also experience changes in hormone levels, including a decrease in leptin, which can affect hunger and satiety.
Additionally, eating too few calories can cause the body to go into “starvation mode,” where it conserves energy by reducing non-essential functions. This can lead to fatigue, weakness, and dizziness, as well as a range of other symptoms. In extreme cases, severe calorie restriction can even lead to organ damage and other serious health problems. It is essential to ensure that you are getting enough calories to support your body’s basic needs, and to consult with a healthcare professional before starting any restrictive diet.
Will I lose weight if I eat only 600 calories a day?
Eating only 600 calories a day will likely result in weight loss, at least in the short term. When the body is not getting enough calories, it will use stored energy sources, such as fat, to make up the difference. This can lead to a rapid weight loss, especially in the first few weeks. However, this weight loss is often not sustainable, and it can be difficult to maintain once you return to a normal calorie intake.
Furthermore, much of the weight lost on a very low-calorie diet is likely to be muscle mass, rather than fat. This can slow down your metabolism, making it harder to lose weight in the long term. Additionally, restrictive dieting can lead to a range of negative side effects, including nutrient deficiencies, fatigue, and a higher risk of chronic diseases. A more sustainable approach to weight loss is to focus on making healthy lifestyle changes, such as increasing physical activity and eating a balanced diet.
What are the risks of eating only 600 calories a day?
Eating only 600 calories a day can pose a range of health risks, particularly if it is continued for an extended period. One of the most significant risks is nutrient deficiency, as it can be challenging to get enough essential vitamins and minerals on such a low-calorie diet. This can lead to a range of health problems, including fatigue, weakness, and impaired immune function.
Other risks associated with very low-calorie diets include a higher risk of osteoporosis, hair loss, and poor wound healing. Additionally, restrictive dieting can lead to disordered eating patterns and a higher risk of eating disorders, such as anorexia nervosa. It is essential to prioritize your overall health and well-being, rather than focusing solely on weight loss. If you are considering a very low-calorie diet, it is crucial to consult with a healthcare professional to discuss the potential risks and benefits.
Can I eat only 600 calories a day and still get enough nutrients?
It can be challenging to get enough nutrients on a 600-calorie diet, particularly if you are not careful about the foods you choose. To ensure that you are getting enough essential vitamins and minerals, it is crucial to focus on nutrient-dense foods, such as fruits, vegetables, whole grains, and lean protein sources. You may also need to consider taking supplements to fill any nutritional gaps.
However, even with careful planning, it can be difficult to get enough of certain nutrients on a very low-calorie diet. For example, it may be challenging to get enough protein, healthy fats, and fiber, which are essential for maintaining good health. Additionally, restrictive dieting can lead to a range of negative side effects, including fatigue, weakness, and impaired immune function. A more balanced approach to eating is often a better choice, as it allows you to get the nutrients you need while also supporting your overall health and well-being.
How long can I safely eat only 600 calories a day?
It is not recommended to eat only 600 calories a day for an extended period. While it may be safe to follow a very low-calorie diet for a short period, such as a few weeks, under the close supervision of a healthcare professional, it is not a sustainable or healthy approach to eating in the long term. Prolonged calorie restriction can lead to a range of negative side effects, including nutrient deficiencies, fatigue, and a higher risk of chronic diseases.
In general, it is recommended to aim for a more balanced approach to eating, with a daily calorie intake that supports your body’s basic needs. For most adults, this means consuming at least 1,200-1,600 calories per day, although individual calorie needs may vary depending on factors such as age, sex, and physical activity level. If you are considering a very low-calorie diet, it is essential to consult with a healthcare professional to discuss the potential risks and benefits.
Can eating only 600 calories a day affect my hormones?
Eating only 600 calories a day can affect hormone levels in the body, particularly those related to hunger and satiety. When the body is not getting enough calories, it can lead to changes in hormone levels, including a decrease in leptin, which helps regulate energy balance and body weight. This can lead to increased hunger and a higher risk of overeating when you do eat.
Additionally, very low-calorie diets can also affect other hormone levels, including a decrease in insulin-like growth factor-1 (IGF-1), which is important for growth and development. This can lead to a range of negative side effects, including fatigue, weakness, and impaired immune function. Furthermore, restrictive dieting can also lead to changes in cortisol levels, which can affect stress and anxiety. It is essential to prioritize your overall health and well-being, rather than focusing solely on weight loss.
Can I eat only 600 calories a day and still exercise regularly?
It is not recommended to eat only 600 calories a day and exercise regularly. When you are not getting enough calories, it can be challenging to support your energy needs, particularly if you are engaging in regular physical activity. This can lead to fatigue, weakness, and a higher risk of injury or illness.
Additionally, very low-calorie diets can also affect your performance and progress in exercise. When you are not fueling your body adequately, you may not have the energy to perform at your best, and you may not be able to recover properly after exercise. This can lead to a range of negative side effects, including decreased muscle mass, decreased bone density, and a higher risk of chronic diseases. A more balanced approach to eating and exercise is often a better choice, as it allows you to support your energy needs and achieve your fitness goals in a healthy and sustainable way.
