What Breaks a Fast? Foods, Drinks, and Supplements: A Comprehensive Guide for Beginners

Fasting has gained popularity in recent years as a way to improve health, promote weight loss, and even boost cognitive function. But what exactly is fasting, and what breaks a fast? In this comprehensive guide, we will explore the ins and outs of fasting, including the types of fasting, the foods and drinks that break a fast, and the supplements that can be consumed while fasting.

Types of Fasting

Fasting can take on various forms, each with its own unique set of rules and benefits. Here are some of the most common types of fasting:

  • Intermittent Fasting (IF): This involves cycling between periods of fasting and eating. The most popular IF methods include the 16/8 method, where you fast for 16 hours and eat within an 8-hour window, and the 5:2 method, which involves eating normally for 5 days and restricting calorie intake to 500-600 calories for 2 non-consecutive days.

  • Water Fasting: This is a more extreme form of fasting where only water is consumed for a set period of time. Water fasting typically lasts for 24-72 hours but can be longer depending on individual goals and health conditions.

Foods to Avoid While Fasting

When it comes to fasting, it’s important to know which foods and drinks can break your fast. Here are some foods to avoid while fasting:

  • High-calorie and processed foods: These foods can spike insulin levels and disrupt the fasting state. Examples include sugary snacks, fast food, and processed snacks.

  • Foods containing carbohydrates and sugars: Consuming foods high in carbs and sugars can lead to an increase in blood sugar levels, which can break a fast. Avoid foods like bread, pasta, rice, and sweets.

  • Foods with artificial additives and sweeteners: Artificial additives and sweeteners can trigger an insulin response and break a fast. Be wary of foods labeled ‘sugar-free’ or ‘diet’ as they often contain these additives.

When it comes to beverages, here are some that break a fast:

  • Sugary drinks and fruit juices: These beverages are high in calories and sugar, which can disrupt the fasting state. Opt for water or unsweetened herbal teas instead.

  • Milk and dairy products: Dairy products contain lactose, a type of sugar that can break a fast. Avoid milk, cream, and other dairy-based beverages while fasting.

  • Alcoholic beverages: Alcohol is high in calories and can interfere with the fasting process. It’s best to abstain from alcohol while fasting.

Safe Foods and Drinks During Fasting

While there are many foods and drinks to avoid while fasting, there are also options that are safe to consume. Here are some examples:

  • Zero-calorie beverages: Water, black coffee, and tea without any additives or sweeteners are safe to consume during fasting. These beverages do not contain any calories or nutrients that can break a fast.

  • Supplements and their impact on fasting: When it comes to supplements, it’s important to choose ones that do not interfere with the fasting state. Here are some supplements that are generally safe to consume while fasting:

    • Vitamins and minerals: Most vitamins and minerals are safe to take while fasting. However, it’s best to consult with a healthcare professional to ensure you’re taking the right ones for your specific needs.

    • Electrolytes: Electrolyte supplements can help replenish essential minerals lost during fasting. Look for options that do not contain any added sugars or calories.

    • Protein powders and branched-chain amino acids (BCAAs): These supplements can be consumed during fasting to support muscle growth and recovery. However, it’s important to choose options that do not contain any added sugars or calories.

    • Pre-workout supplements: Some pre-workout supplements contain ingredients that may break a fast, such as sugars or artificial additives. It’s best to check the label and choose options that are specifically designed for fasting.

Common Misconceptions about Fasting

Fasting is surrounded by various myths and misconceptions. Let’s debunk some of the most common ones:

  • Myth: Fasting slows down metabolism. Fact: Fasting can actually boost metabolism and promote fat burning.

  • Myth: Fasting leads to muscle loss. Fact: When done properly, fasting can help preserve muscle mass.

  • Myth: Fasting is only for weight loss. Fact: While weight loss is a common goal of fasting, it also offers numerous other health benefits, including improved insulin sensitivity and reduced inflammation.


In conclusion, fasting can be a powerful tool for improving health and achieving weight loss goals. However, it’s important to understand what breaks a fast to ensure optimal results. Avoid high-calorie and processed foods, foods high in carbohydrates and sugars, and foods with artificial additives and sweeteners while fasting. Stick to zero-calorie beverages like water, black coffee, and tea, and choose supplements that do not interfere with the fasting state. Remember to consult with a healthcare professional or registered dietitian before making any significant changes to your fasting or dietary habits.
