How Long Can Bearded Dragons Go Without Food?

Curious about your bearded dragon’s dining habits? Let’s dive right in. Bearded dragons can typically go without food for about 1 to 2 weeks without significant concerns. However, understanding the nuances of their fasting behavior is essential for responsible reptile care.

How Often Should Bearded Dragons Be Fed?

Feeding frequency for juveniles

Juvenile bearded dragons are in a stage of rapid growth and development, and they require more frequent feedings compared to adults. Aim to feed them two to three times a day. Offer a variety of appropriately sized insects such as crickets, mealworms, and small dubia roaches. Additionally, include fresh vegetables and greens to provide a well-rounded diet rich in vitamins and minerals.

As a young bearded dragon, their diet should consist of about 80% protein (insects) and 20% vegetables and greens. This balance helps support their growth and provides essential nutrients for bone development.

Feeding frequency for adults

Adult bearded dragons have different dietary requirements than juveniles. At this stage, you can transition to feeding them once a day. Their diet should now consist of about 80% vegetables and greens, and 20% protein. Adult dragons still benefit from the occasional insect meal, but the emphasis shifts towards a more plant-based diet.

We recommend you monitor their weight and adjust the amount of food accordingly. Overfeeding can lead to obesity, which may have adverse effects on their health.

Maintaining a balanced diet is crucial for the overall well-being of bearded dragons at any stage of life. A well-rounded diet ensures they receive the necessary nutrients for proper growth, bone health, and overall vitality.

Providing a variety of food options helps prevent nutritional deficiencies and encourages the natural foraging behavior of these reptiles. Calcium and vitamin supplements may also be necessary, especially for growing juveniles and females during egg-laying periods.

Always ensure fresh water is available, and dusting insects with a calcium supplement can contribute to their calcium intake.

What Factors Influence Bearded Dragons’ Feeding Frequency?

  1. Age: The age of a bearded dragon significantly impacts its feeding frequency. Juveniles, in their rapid growth phase, require more frequent meals, typically two to three times a day. As they mature into adults, the frequency decreases to once a day or even every other day.
  2. Metabolic Rate: Bearded dragons, like all reptiles, have a metabolic rate that varies with factors such as temperature and activity level. Warmer temperatures usually increase metabolism, leading to a higher need for food. Conversely, during cooler periods or brumation (a form of hibernation), their metabolism slows down, and they may eat less frequently.
  3. Health Status: The health of a bearded dragon plays a vital role in its appetite. Illness, injury, or stress can affect their eating habits. Monitoring their behavior, appearance, and bowel movements is essential to detect any signs of health issues that might impact their feeding.
  4. Seasonal Changes: Bearded dragons may exhibit changes in appetite based on seasonal variations. During the breeding season, for example, males may eat less, and females might increase their intake. Understanding these natural patterns helps in adjusting their diet accordingly.
  5. Diet Composition: The type and variety of food offered influence a bearded dragon’s feeding habits. A balanced diet that includes a mix of protein (insects) and vegetables is crucial. If their diet lacks variety or essential nutrients, it can impact their appetite and overall health.
  6. Environmental Conditions: The conditions within their enclosure, such as lighting, temperature, and humidity, can affect a bearded dragon’s appetite. Ensure that their habitat replicates their natural environment as closely as possible for optimal health and feeding behavior.
  7. Individual Preferences: Each bearded dragon is unique, and individual preferences can play a role in their feeding habits. Some may prefer certain types of insects or vegetables, so offering a variety of food ensures they receive a well-rounded diet.

How Can You Determine if Your Bearded Dragon is Hungry or Malnourished?

On the contrary, malnourished dragons may exhibit lethargy, weight loss, or a lack of interest in food. Check for any unusual changes in appearance, such as sunken eyes or prominent bones, which could signal malnutrition. Regularly monitor bowel movements for consistency.

If you notice prolonged disinterest in food, consult a reptile veterinarian promptly. In essence, attentive observation and responsiveness to your bearded dragon’s signals are key in maintaining its health and addressing any potential nutritional concerns.

How Long Can Bearded Dragons Safely Go Without Food?

Bearded dragons can safely go without food for about 1 to 2 weeks. Factors like age, health, and environmental conditions influence their fasting duration. Juveniles, being in a growth phase, may need more frequent meals, while adults can sustain longer periods between feedings.

Risks Associated with Prolonged Fasting in Bearded Dragons?

  1. Weight Loss and Muscle Wasting: Extended fasting can lead to significant weight loss and muscle wasting in bearded dragons, particularly in juveniles and those already in a weakened state.
  2. Nutritional Deficiencies: Lack of food intake for an extended period can result in nutritional deficiencies. Bearded dragons require a balanced diet for essential vitamins and minerals; prolonged fasting may lead to imbalances and health issues.
  3. Weakened Immune System: Insufficient nutrition weakens the immune system, making bearded dragons more susceptible to infections and illnesses.
  4. Organ Dysfunction: Prolonged fasting can impact organ function, particularly the liver and kidneys. These organs play a crucial role in digestion and waste elimination.
  5. Bone Health Issues: Bearded dragons are prone to metabolic bone disease (MBD) if calcium intake is inadequate. Prolonged fasting can exacerbate this risk, affecting bone density and structure.
  6. Reproductive Problems: Female bearded dragons may experience reproductive issues if they are malnourished, leading to complications during egg-laying.
  7. Dehydration: Lack of food intake is often associated with reduced water consumption, potentially leading to dehydration. Proper hydration is essential for overall health.
  8. Behavioral Changes: Prolonged fasting can result in lethargy, apathy, and changes in behavior. A normally active and curious dragon may become sluggish or unresponsive.

Here’s a step-by-step guide, considering both juvenile and adult bearded dragons:

For Juvenile Bearded Dragons

  • Check Environmental Conditions: Ensure the enclosure temperature and lighting mimic their natural habitat. Incorrect conditions can impact appetite. Aim for a basking spot of around 95-100°F (35-38°C) and a cooler side around 80°F (27°C).
  • Assess Diet Composition: Confirm you are offering a varied diet suitable for juveniles. They require a higher protein intake, so ensure a good mix of appropriately sized insects, such as crickets and small dubia roaches, along with finely chopped vegetables.
  • Monitor for Parasites: Young dragons are more susceptible to parasites. A fecal examination by a reptile veterinarian can rule out parasitic infections, a common cause of appetite loss.
  • Check for Mouth or Dental Issues: Inspect the mouth for signs of injury or infection. Dental issues can affect eating habits. If you notice any abnormalities, consult a veterinarian.
  • Consider Brumation: Juvenile dragons don’t typically brumate, but stress or incorrect conditions may mimic this behavior. Ensure their environment is stable and comfortable.

For Adult Bearded Dragons

  • Evaluate Diet Composition: Adult bearded dragons need a balanced diet with a higher proportion of vegetables. Ensure you are offering a mix of leafy greens, vegetables, and occasional insect feedings.
  • Temperature and Lighting: Confirm that the basking and ambient temperatures are suitable. Adult dragons generally prefer slightly lower temperatures than juveniles, so adjust accordingly.
  • Veterinary Check-Up: If refusal persists, consult with a reptile veterinarian. They may perform blood tests to check for underlying health issues like metabolic bone disease or organ dysfunction.
  • Dental Examination: Dental problems can affect older dragons. Inspect for signs of mouth issues, and if in doubt, seek professional veterinary advice.
  • Behavioral Observation: Monitor overall behavior. Changes in activity levels, lethargy, or abnormal postures may indicate underlying health problems.
  • Hydration: Ensure your dragon is adequately hydrated. Dehydration can impact appetite. Provide fresh water and consider occasional bathing to encourage drinking.


Addressing a bearded dragon’s refusal to eat involves assessing environmental conditions, diet composition, and potential health issues. For juveniles, focus on proper temperature, a protein-rich diet, and monitoring for parasites.

Adults require a balanced diet with attention to dental health and a comfortable habitat. Regular veterinary check-ups are essential for both age groups.

Patience and vigilance are paramount. Be proactive in maintaining a suitable environment, offering a diverse and nutritious diet, and seeking professional veterinary advice promptly if appetite issues persist. A holistic approach ensures the long-term health and happiness of your cherished bearded dragon.
