This deficit will help you achieve weight loss while still providing enough energy for your body to function properly.

It’s important to consult with a healthcare professional or registered dietitian to determine your specific calorie needs based on your age, gender, activity level, and other factors.

What Happens if You Consume Too Many Calories During Intermittent Fasting?

If you consume too many calories during your eating periods, you may not see the weight loss results you desire.

Consistently consuming more calories than you burn can lead to weight gain and other negative health outcomes.

However, it’s important to have balance and not become obsessive about calorie counting. Intermittent fasting can still be beneficial for overall health even if you occasionally consume more calories than intended.

What Foods Should You Consume During Intermittent Fasting?

Avoid highly processed foods, sugary drinks, and foods high in saturated and trans fats. These foods provide little nutritional value and can contribute to negative health outcomes.

Do Calories Matter When Intermittent Fasting?


In conclusion, determining the number of calories to consume during intermittent fasting can be a bit of a challenge. However, it is important to keep in mind that the goal is not about restricting calories but rather about giving your body the time it needs to heal and repair itself.

It is recommended that you consult with a healthcare professional or a registered dietitian to determine the appropriate caloric intake for your body type and lifestyle. Additionally, it is important to focus on consuming nutrient-dense foods during your eating windows to ensure that you are getting the necessary vitamins and minerals your body needs.

Remember, intermittent fasting is not a one-size-fits-all approach, and it may take some time to find what works best for you. Listen to your body, be patient, and don’t forget to enjoy the journey towards a healthier lifestyle.
