What is OK during fasting?

Published in Fasting Guidelines 1 min read

During fasting, consuming water and zero-calorie beverages is permitted.

Essentially, you're aiming to keep your calorie intake at zero during the fasting period. This helps your body enter the desired metabolic state. Here's a breakdown of what's usually acceptable, based on maintaining that zero-calorie goal:

Acceptable Beverages During Fasting

The following beverages generally do not break a fast:

  • Water: Plain water is always a good choice and essential for hydration.
  • Black Coffee: Without any milk, sugar, or sweeteners, black coffee is typically acceptable.
  • Tea: Plain, unsweetened tea (herbal, black, green, etc.) is usually fine.

Key Considerations

  • Zero-Calorie Beverages: As long as a beverage truly has zero calories, it should be acceptable. Be cautious of hidden sugars or calories in seemingly "diet" or "zero-calorie" options. Read labels carefully.
  • Artificial Sweeteners: The impact of artificial sweeteners is debated. Some believe they can trigger an insulin response, potentially breaking the fast, while others find them acceptable.
  • Listen to Your Body: Pay attention to how your body responds to different beverages during your fast.
