A 900-calorie diet is a weight-loss plan that involves limiting your daily caloric intake to approximately 900 calories. This can be achieved by consuming 300 calories per meal (breakfast, lunch, and dinner), trying intermittent fasting with two larger meals of 450 calories each, or even trying the OMAD (one meal a day) diet. While this diet can lead to rapid weight loss, it is considered a very low-calorie diet (VLCD) and may not be sustainable or healthy for most adults. Without medical supervision, it can lead to short-term side effects like fatigue, nausea, and headaches, as well as long-term health risks such as gallstones and nutrient deficiencies. It is important to consult with a healthcare professional before starting any drastic diet plan like this one.

Potential side effects
A 900-calorie diet plan involves limiting your daily caloric intake to approximately 900 calories. This can be achieved by consuming 300 calories per meal, i.e., breakfast, lunch, and dinner, or through intermittent fasting, with slightly bigger meals of 450 calories. Some people even opt for the OMAD (one meal a day) diet, where they consume a 900-calorie meal once per day.
However, a 900-calorie diet is considered a very low-calorie diet and can lead to several potential side effects, both short-term and long-term. Here are some of the possible side effects you may experience:
Short-term side effects:
- Fatigue: You may experience tiredness and a lack of energy due to the reduced caloric intake.
- Constipation or diarrhea: The diet can disrupt your digestive system, leading to either of these issues.
- Nausea: Feelings of sickness or upset stomach may occur due to the restricted diet.
- Dry mouth: Reduced food intake can result in decreased saliva production, causing a dry mouth.
- Cramps: Muscle cramps or abdominal cramps may be experienced due to electrolyte imbalances or dehydration.
- Headaches: These can be a result of dehydration, low blood sugar, or nutrient deficiencies.
- Dizziness: Dizziness or lightheadedness can occur due to reduced blood sugar or inadequate nutrition.
- Extreme hunger: The diet may not provide sufficient energy, leading to intense feelings of hunger.
Long-term side effects:
- Gallstones: When you don't consume enough food or lose weight rapidly, the liver secretes more cholesterol into bile, which can form gallstones.
- Hair loss: Prolonged adherence to a very low-calorie diet can lead to hair loss due to nutritional deficiencies.
- Nutritional deficiencies: A 900-calorie diet may not provide all the essential nutrients your body needs, leading to deficiencies over time.
- Weight regain: Very low-calorie diets can lead to rebound binge eating when extreme hunger sets in. This may result in weight regain or even weight gain beyond the original starting point.
- Health problems: Without proper nutrition, you may develop or exacerbate existing health issues.
It is important to note that a 900-calorie diet should only be considered under medical supervision and for specific health reasons. Consult with a healthcare professional before making any drastic changes to your diet to ensure your safety and well-being.

Meal frequency
Three Meals a Day
One approach is to divide the daily calorie allowance into three equal meals, with each meal containing approximately 300 calories. This can include breakfast, lunch, and dinner, providing a structured routine for meal times throughout the day.
Intermittent Fasting
Another option is to practice intermittent fasting, which involves alternating between periods of eating and fasting. This method doesn't require strict calorie counting but focuses on when you eat. For example, you might have two slightly larger meals a day, each consisting of approximately 450 calories. Intermittent fasting has been associated with improved metabolic health and potential longevity benefits.
One Meal a Day (OMAD)
Some individuals may opt for the extreme approach of consuming their entire daily calorie allowance in one meal, known as the OMAD (one meal a day) diet. This means eating a single 900-calorie meal, which can be challenging and may not be suitable for everyone.
Customizable Plans
There are also customizable meal plans available online that allow you to tailor your calorie intake to your specific needs and preferences. These plans can help you create recipes, track your intake, and generate grocery lists to support your 900-calorie diet.
It is important to note that a 900-calorie diet is considered a very low-calorie diet (VLCD) and may not be suitable for everyone. Such diets are typically supervised by medical professionals and are designed for rapid weight loss in specific situations. Prior to starting a 900-calorie diet or any significant dietary changes, it is strongly advised to consult with a healthcare provider or registered dietitian to ensure it is safe and appropriate for your individual needs.

Medical supervision
A 900-calorie diet is a very low-calorie diet (VLCD) and is considered a rapid weight-loss program. It is a drastic change in eating habits and can lead to a caloric intake that may be insufficient to properly sustain an adult.
Due to the extreme nature of the 900-calorie diet, it is not recommended without medical supervision. A doctor will be able to advise if this diet is suitable for you, taking into account your individual circumstances, such as age, sex, lifestyle, level of physical activity, and height.
For example, very low-calorie diets are not normally used for patients with a BMI between 27 and 30 unless they have medical conditions related to their weight, such as diabetes or high blood pressure. These diets are also not usually considered appropriate for older people or children and teens due to potential side effects and medication needs.
If you decide to proceed with a 900-calorie diet, it is important to do so under strict medical supervision. A healthcare provider can help monitor for any signs of metabolic slowdown, muscle loss, and weight loss plateaus, which can lead to long-term health complications. They can also advise on any required behaviour changes to ensure long-term healthy eating habits.
Additionally, a doctor may prescribe meal replacement products that are specially formulated to contain adequate vitamins and nutrients, ensuring your nutritional requirements are met.

Calorie-counting
To adhere to a 900-calorie diet, individuals must carefully track their food and drink intake to stay within the calorie limit. This typically involves consuming 300 calories per meal (breakfast, lunch, and dinner) or trying intermittent fasting with two larger meals of 450 calories each. Some people may even opt for the OMAD (one meal a day) diet, consuming their entire 900-calorie intake in one meal.
While calorie-counting is essential for staying within the strict limits of a 900-calorie diet, it is crucial to prioritize health and well-being. This type of diet can lead to short-term side effects like fatigue, nausea, and headaches, and in the long term, gallstones and severe nutrient deficiencies may develop. It is not recommended without medical or professional supervision due to the potential health risks and should only be considered in specific situations under appropriate guidance.
Additionally, it is worth noting that very low-calorie diets are not a one-size-fits-all solution, and individual differences should be considered. Factors such as age, sex, lifestyle, physical activity levels, and height all play a role in determining the recommended calorie intake for an individual. For most adults, a 900-calorie diet is unsustainable and may lead to a miserable and dangerous experience, with potential long-term health consequences.

Alternative diets
A 900-calorie diet is a very low-calorie diet (VLCD) that restricts daily caloric intake to 800–900 calories. This diet may not provide enough energy for adults to function properly and may lead to short-term side effects like fatigue, constipation, nausea, dry mouth, cramps, headaches, and dizziness. More severely, gallstones may develop as a long-term effect.
Mediterranean Diet
This diet includes a balance of whole grains, fruits, vegetables, legumes, nuts, and fish. It supports weight management and provides anti-inflammatory and antioxidant benefits, improving overall health and preventing diseases.
Vegan Diet
A well-planned vegan diet can help with weight reduction and improved heart health. It encourages the exploration of a variety of plant-based foods, which can be both creative and fulfilling.
Intermittent Fasting
This method alternates between periods of eating and fasting, which can lead to a natural reduction in calorie intake. It has been linked to health benefits like improved metabolic health and possibly a longer lifespan.
Whole30, Low FODMAP, and Pescetarian Diets

A 900-calorie diet is considered a very low-calorie diet (VLCD) and is a rapid weight-loss program. It is recommended that you consult a doctor or dietitian before starting this diet. Foods that can be included in this diet are complex carbohydrates like brown rice, oats, and quinoa; low-calorie fruits such as strawberries and grapefruits; vegetables, especially dark leafy greens like kale and Swiss chard; and proteins from lean meats and oily fish rich in omega-3 fatty acids. Beverage choices are limited to water, black coffee, green tea, and herbal teas.
A 900-calorie diet is not recommended for most people as it can be considered a starvation diet and may lead to short-term side effects like fatigue, nausea, and headaches. It is almost always prescribed for medical reasons to help manage obesity and related conditions when other weight-loss attempts have failed.
A 900-calorie diet may lead to rapid weight loss in the short term. However, it can be difficult to sustain and may lead to long-term health risks such as gallstones and severe nutrient deficiencies. It may also lead to increased irritability and a negative impact on mental health. Safer and more sustainable methods of weight loss that do not compromise health are often recommended instead.
