While bearded dragons can survive without food for 1-2 weeks, it is not recommended to deprive them of regular meals. A consistent diet is vital for their overall health and well-being. If you are going to be away for an extended period, it is essential to arrange for someone to care for your bearded dragon and provide them with their dietary requirements.

Metabolism and Energy Requirements of a Bearded Dragon


Energy Requirements

Generally, a bearded dragon’s diet should consist of a balance between protein, fruits, and vegetables. Protein-rich foods like insects and small rodents provide the necessary energy for growth and maintenance. Fruits and vegetables, on the other hand, contribute to proper digestion and the supply of essential vitamins and minerals.

Bearded dragons have a unique digestive system that allows them to efficiently process and absorb nutrients from their food. They have a high calcium requirement, as it is crucial for the development and maintenance of their bones and overall health. Calcium-rich foods, such as calcium powder or calcium-rich vegetables, should be included in their diet.

Food Storage and Feeding Patterns

Food Storage

Furthermore, live insects should be gut-loaded before being fed to the bearded dragon. Gut-loading refers to feeding the insects with nutrient-rich foods to enhance their nutritional content before they are consumed by the reptile. This ensures that the bearded dragon receives an adequate amount of nutrients from its prey.

Feeding Patterns

Bearded dragons are diurnal creatures, meaning they are active during the day and sleep at night. Their feeding patterns are influenced by their natural habitat, which consists of arid regions with limited food resources. In the wild, they typically forage for food in the morning and early afternoon when temperatures are optimal.

When kept as pets, bearded dragons should be provided with a consistent feeding schedule. They should be offered food twice per day, with meals spaced out in the morning and afternoon. This mimics their natural feeding habits and allows them to regulate their metabolism accordingly.

Additionally, the size of the food provided should be appropriate for the bearded dragon’s age and size. Juveniles may require smaller prey and more frequent feedings, while adults can eat larger prey less frequently. Monitoring their weight and adjusting the portion sizes accordingly is essential to prevent overfeeding or underfeeding.

Factors affecting how long a bearded dragon can live without food


Metabolism plays a significant role in determining how long a bearded dragon can live without food. Bearded dragons have a relatively slow metabolism compared to mammals. This means they can survive for longer periods without food compared to other animals. However, the exact duration they can go without eating depends on several factors.

Age and size

The age and size of a bearded dragon can also affect how long it can survive without food. Younger dragons that are still growing and developing have higher energy requirements. They need to eat more frequently compared to adult dragons. Generally, adult bearded dragons can go longer without food compared to juveniles and hatchlings.

Overall health and weight

The overall health and weight of a bearded dragon also play a crucial role in determining how long it can survive without food. A healthy dragon with a proper body weight will have more energy stores to rely on during periods of food scarcity. On the other hand, an underweight or sick dragon will have limited energy reserves and may not survive for long without food.

Environment and temperature

The environment and temperature in which a bearded dragon is kept can impact its food consumption and energy requirements. Cold temperatures can slow down a dragon’s metabolism, making it difficult for them to digest food. Additionally, extreme temperatures can also affect their appetite and overall health. Therefore, maintaining a suitable temperature range is important to ensure a healthy appetite and prevent potential complications.

Stress and emotional well-being

Stress and emotional well-being can also affect a bearded dragon’s food consumption and overall health. Like humans, bearded dragons can experience stress, which can lead to a loss of appetite. Stressors can include changes in their environment, handling, or the presence of other animals. Creating a stress-free and stimulating environment can help ensure a healthy appetite and overall well-being for your bearded dragon.

The bottom line

The potential risks of not feeding a bearded dragon

Feeding is a vital aspect of a bearded dragon’s life, and not providing them with food can have serious consequences. Bearded dragons are omnivorous reptiles, meaning they require a balanced diet consisting of both animal protein and plant matter to meet their nutritional needs.

Without proper nutrition, a bearded dragon’s health can deteriorate rapidly. One of the most significant risks of not feeding a bearded dragon is malnutrition. A lack of essential nutrients can lead to various health issues, including weakened immune system, stunted growth, bone disorders, and reproductive problems.

In addition to malnutrition, not feeding a bearded dragon can result in weight loss and muscle wasting. Bearded dragons rely on stored fat reserves to provide energy when food is scarce. If they go without food for an extended period, these fat reserves will deplete, leading to weight loss and weakness.

Another risk of not feeding a bearded dragon is dehydration. Bearded dragons obtain a portion of their hydration from the food they consume. Without regular food intake, they may not be getting enough moisture, which can lead to dehydration and associated health complications.

Furthermore, not feeding a bearded dragon can lead to behavioral issues. When hungry, bearded dragons may become more aggressive, restless, or even exhibit unusual foraging behavior. It is their natural instinct to search for food, and not fulfilling this instinct can affect their overall well-being.

Overall, not feeding a bearded dragon can have severe implications for their health and well-being. It is essential to provide them with a proper diet that meets their nutritional requirements to ensure they lead a healthy and happy life. Regular feeding schedules, along with a varied and balanced diet, are key to maintaining a bearded dragon’s optimal health.

How long can a bearded dragon survive without food?

Bearded dragons are omnivores and their diet consists of a variety of insects, vegetables, fruits, and greens. They need a combination of animal and plant-based foods to meet their nutritional needs. In the absence of food, a bearded dragon’s body begins to rely on its fat stores for energy. However, prolonged fasting can lead to weight loss, muscle wasting, and weakened immune function.

When a bearded dragon doesn’t have access to food, its energy requirements decrease as its metabolic rate slows down. This is an adaptive mechanism that allows them to conserve energy and survive in times of scarcity. However, this does not mean they can go indefinitely without eating.

Food storage and feeding patterns also play a role in how long a bearded dragon can survive without food. They have the ability to store energy in their fat reserves and can adjust their feeding patterns based on food availability. However, these reserves are limited, and if they are not replenished, the bearded dragon will eventually starve.

Several factors can affect a bearded dragon’s food consumption and the length of time they can survive without eating. These include age, health, temperature, and activity level. Younger and healthier dragons tend to have higher energy requirements and may not be able to tolerate prolonged fasting as well as older or less active individuals.

Not feeding a bearded dragon for an extended period of time can have serious consequences. It can lead to malnutrition, weakened immune system, organ failure, and ultimately death. Regular feeding and providing a balanced diet is essential for the overall health and well-being of a bearded dragon.
