If you’re trying to navigate the world of intermittent fasting, you might wonder: does adding unsweetened almond milk to your coffee break your fast? In this blog post, we will unpack this question, giving you the information you need to make the best decision for your health.

Author’s Note

Intermittent fasting has been great for my mental clarity. When I fast, I only have water and black coffee, no unsweetened almond milk or anything else. Keeping it simple with just water and coffee works best for me, helping me stay focused and feel great during fasting. If you’re considering intermittent fasting, remember you don’t have to add anything to your coffee. Stick to water and plain coffee to reap the benefits. Let’s explore the scientific evidence behind it.

Does Unsweetened Almond Milk in Coffee Break a Fast?

Intermittent fasting involves abstaining from food and caloric beverages for a certain period, usually between 12 and 24 hours. The goal is to allow your body to enter a fasting state, which relies on stored fat for energy instead of glucose from food.

Adding unsweetened almond milk, a popular choice for those looking to cut down on dairy products or artificial sweeteners, to your cup of coffee can be a point of contention for some fasting enthusiasts. The concern stems from almond milk containing a small number of calories and trace amounts of protein and carbohydrates.

But, the overall impact of these nutrients on your fasting state is minimal, and it’s unlikely to significantly disrupt the benefits of intermittent fasting.

While the actual caloric content of almond milk can vary depending on the brand and specific product, it generally contains around 30 calories per cup. This is a negligible amount compared to most individuals’ daily caloric intake.

Moreover, unsweetened almond milk’s protein and carbohydrate content is relatively low, with approximately 1 gram of protein and less than 1 gram of carbohydrates per cup.

The Impact of Unsweetened Almond Milk on Insulin and Autophagy

To better understand the impact of adding unsweetened almond milk to coffee while fasting, let’s explore its potential effects on two important aspects of fasting: insulin levels and autophagy.

Insulin Levels

Insulin is a hormone that plays a crucial role in regulating blood sugar levels. When you consume food or beverages that contain calories, including unsweetened almond milk, your body releases insulin to manage the incoming glucose1. This insulin response can temporarily interrupt the fasting state and affect insulin sensitivity.

Nevertheless, unsweetened almond milk, with its low carbohydrate content and zero added sugar, has a minimal impact on insulin levels compared to other milk alternatives. It’s an excellent choice for maintaining lower insulin levels during fasting, which can promote better insulin sensitivity and help regulate blood glucose levels.


Autophagy is a natural cellular process in which the body breaks down and recycles old or damaged cells. It’s believed to have several health benefits, including improved cellular function and potential anti-aging effects. Fasting triggers autophagy as the body adapts to the absence of food.

While drinking unsweetened almond milk in coffee may slightly decrease autophagy compared to a strict water-only fast, it’s crucial to note that autophagy is a continuum. Even a partial activation of autophagy can have significant health benefits. Therefore, incorporating unsweetened almond milk into your fasting routine is unlikely to halt the benefits of autophagy completely.

Factors to Consider

While unsweetened almond milk is generally considered acceptable during fasting, it’s important to consider individual factors affecting your fasting goals and overall health. Here are a few factors to consider:

1. Caloric intake

Although the calorie content of unsweetened almond milk is low, if you consume large quantities throughout your fasting window, the cumulative calories may exceed the fasting threshold. To stay within the desired range, it’s critical to be mindful of your overall caloric intake during fasting periods.

2. Personal Goals

The primary goal of intermittent fasting varies among individuals. If your main objective is weight loss, the minimal calories in unsweetened almond milk will unlikely hinder your progress. But, if autophagy (the cellular repair process) is your focus, you may prefer to avoid any caloric intake during fasting to optimize its benefits.

3. Sensitivity to Insulin

Some individuals may have higher insulin sensitivity; even small amounts of protein or carbohydrates can trigger a more significant insulin response. Suppose you find that adding unsweetened almond milk affects your energy levels or hunger during fasting. In that case, you may want to eliminate it from your routine or try other milk alternatives.

4. Digestive Sensitivity

Individuals may experience digestive issues, such as bloating or discomfort, when drinking almond milk. If this applies to you, avoiding almond milk during fasting is advisable to ensure a comfortable experience and maintain overall digestive health.

Remember, the ultimate goal of intermittent fasting is to find an approach that works best for your body and lifestyle. It’s important to listen to your body’s cues and adjust accordingly.

Unsweetened Almond Milk & Fasting: Benefits vs. Drawbacks

If you’re fasting and love your coffee, adding a bit of unsweetened almond milk could be a game-changer. It not only makes your black coffee creamier and tastier without messing up your fast, but it also comes with some health perks. The healthy fats in almond milk can give you a steady stream of energy and help your brain work better while you’re fasting. But be careful—if you’re trying to stick to eating absolutely no calories before it’s time to break your fast, this might not be the best idea.


  • Low-calorie alternative: Adding unsweetened almond milk to coffee can enhance its flavor without significantly breaking your fast.
  • Sustained energy and brain health: The healthy fats in almond milk, like monounsaturated fatty acids, provide sustained energy and support brain function during fasting.
  • Curbs hunger and maintains satiety: The presence of fats and proteins in almond milk can help you feel fuller, which can be beneficial for individuals who struggle with hunger during fasting.


  • Individual variations: Everyone’s body reacts differently, so paying attention to your body’s signals and adjusting accordingly is important.
  • Potential impact on fasting state: While the effects are minimal, it’s worth noting that adding almond milk, even unsweetened, may slightly disrupt the fasting state due to its low calorie and nutrient content.

Unsweetened Almond Milk Nutrition

Unsweetened almond milk is a great addition to coffee if you’re fasting, as it provides several benefits without adding unwanted calories or sugar. It is low in calories, carbohydrates, and fats, and it’s packed with essential vitamins and minerals, such as calcium, potassium, Vitamin E, Manganese, Magnesium, and Zinc.

An 8-ounce serving of unsweetened almond milk contains:

  • Calories: 40.
  • Protein: 1 gram.
  • Fat: 3 grams.
  • Carbohydrates: 2 grams.
  • Fiber: 1 gram.
  • Sugar: 0 grams.

These nutrients contribute to healthy skin, hair, bone health, and metabolism. Consuming almond milk in coffee also enhances your daily intake of antioxidants, which can help combat free radicals in the body and reduce inflammation. It can also add a subtle, nutty flavor to your coffee, which many people prefer over dairy creamers.

However, there are a few potential drawbacks. Almond milk has a low-fat content, which might not be ideal for those looking for a creamier option in their coffee. Also, if you have a nut allergy, almond milk would not be a suitable choice for you​​.

The Importance of Calories and Macronutrients

When considering whether unsweetened almond milk in coffee breaks a fast, evaluating the impact of calories and macronutrients is important. Even though unsweetened almond milk is low in calories, it still contains some carbohydrates, proteins, and fats. These macronutrients contribute to overall calorie intake, influencing the fasting state and fat burning.

Drinking no more than 50 calories during the fasting period is generally recommended to maintain a fasting state. Since unsweetened almond milk typically contains around 30-40 calories per cup, adding a small amount to your coffee is unlikely to impact your fasting goals significantly.
