How many calories to eat during intermittent fasting 16/8?


Intermittent fasting has gained popularity as an effective way to manage weight and improve overall health. One of the most common fasting methods is the 16/8 intermittent fasting, where individuals fast for 16 hours and have an eating window of 8 hours. However, a common question that arises is how many calories to consume during the eating window. In this article, we will explore the recommended calorie intake during the 16/8 intermittent fasting and its potential benefits.

Calorie Intake During 16/8 Intermittent Fasting

During the eating window of the 16/8 intermittent fasting, it is essential to consume an adequate amount of calories to meet your body’s nutritional needs. The exact number of calories will vary depending on factors such as age, sex, weight, activity level, and overall health goals. However, a general guideline is to consume the same number of calories as you would during a regular day without fasting.

Calorie Calculation: To determine your calorie intake, you can use various methods such as the Harris-Benedict equation or online calorie calculators. These tools take into account your age, sex, weight, height, and activity level to estimate your daily calorie needs. Once you have determined your daily calorie needs, you can allocate them within your eating window during the 16/8 intermittent fasting.

Macronutrient Distribution: While the total calorie intake is important, it is also crucial to consider the distribution of macronutrients (carbohydrates, proteins, and fats) within your eating window. A balanced distribution of macronutrients ensures that your body receives the necessary nutrients for optimal functioning.

Potential Benefits of 16/8 Intermittent Fasting

16/8 intermittent fasting has been associated with several potential benefits beyond weight management. Some of these benefits include:

Improved Insulin Sensitivity: Intermittent fasting has been shown to improve insulin sensitivity, which is essential for regulating blood sugar levels. This can be particularly beneficial for individuals with prediabetes or type 2 diabetes.

Enhanced Fat Burning: During the fasting period, your body depletes its glycogen stores and starts utilizing stored fat as an energy source. This can lead to increased fat burning and potentially aid in weight loss.

Reduced Inflammation: Intermittent fasting has been found to reduce inflammation in the body, which is associated with various chronic diseases such as heart disease and cancer.

Improved Brain Health: Some studies suggest that intermittent fasting may have neuroprotective effects and improve brain health. It may enhance cognitive function and protect against age-related neurodegenerative diseases.


In conclusion, the recommended calorie intake during the 16/8 intermittent fasting is generally the same as your regular daily calorie needs. It is important to calculate your calorie requirements based on factors such as age, sex, weight, height, and activity level. Additionally, ensure a balanced distribution of macronutrients within your eating window to meet your body’s nutritional needs. 16/8 intermittent fasting has potential benefits beyond weight management, including improved insulin sensitivity, enhanced fat burning, reduced inflammation, and improved brain health.
