The Calorie Breakdown: Why Broth Isn't Zero
While chicken broth is extremely low in calories, it's a common misconception that it contains absolutely none. Calories are a measure of energy, and energy is derived from the macronutrients present in the food and drink we consume: protein, fat, and carbohydrates. Even the clearest broth contains trace amounts of these macronutrients, which come from the simmering of chicken meat, bones, and vegetables.
For example, standard chicken broth typically contains a small amount of protein, usually between 1.5 and 5 grams per cup, which contributes to its overall calorie count. Fat content also plays a role, especially if the fat is not fully skimmed from the surface after simmering. Any carbohydrates from added vegetables like carrots and onions also add to the final total. When you add up the calories from these components, the result is never zero, though it remains very minimal.
Homemade vs. Store-Bought: The Calorie Difference
The caloric value of chicken broth can vary significantly based on whether it is homemade or store-bought, and the specific ingredients used.
Homemade Broth
Homemade chicken broth offers the most control over ingredients and, therefore, calorie content. The primary determinants of calorie count in homemade broth are:
- Meat vs. Bones: Using more meat and skin in the recipe will result in higher calorie and fat content than using just bones.
- Fat Content: Skimming the fat that rises to the top during cooling can dramatically reduce the final calories per serving.
- Vegetables and Herbs: Adding vegetables like carrots or potatoes can introduce more carbs, slightly increasing calories.
- Duration: Longer simmering times for bone broths extract more nutrients and can concentrate flavors, but do not dramatically increase calories unless more ingredients are added.
Store-Bought Broth
Commercial chicken broth offers convenience but requires careful label reading. The calorie count can range from as little as 5 calories per cup for fat-free, no-salt-added versions to over 30 calories for regular varieties.
- Fat-Free Versions: Many brands offer specific fat-free versions where the fat has been removed during processing, resulting in the lowest calorie count possible.
- Regular Varieties: These often contain small amounts of fat and potentially added sugars or flavorings, which increase the calorie content.
- Bone Broth vs. Broth: Store-bought chicken bone broth is typically simmered for much longer and contains more protein, and therefore more calories, than standard chicken broth.
| Feature | Homemade Chicken Broth | Store-Bought Chicken Broth | Store-Bought Chicken Bone Broth | 
|---|---|---|---|
| Calorie Range (per cup) | 10-40+ calories | 5-30 calories | 30-60 calories | 
| Ingredients | Customizable; uses meat, bones, vegetables | Standardized; can have added flavorings, preservatives | Uses bones; often higher in protein and collagen | 
| Nutrient Density | High; depends on ingredients and simmer time | Varies; often lower in nutrients than homemade | Highest; richest in protein and minerals | 
| Sodium Content | Fully controllable | Often high; low-sodium options available | Varies by brand; often higher than standard broth | 
| Fat Content | Customizable; can be fully skimmed | Varies; fat-free versions available | Varies; depends on processing | 
Chicken Broth and Dieting: More Than Just Calories
For those on a keto diet or intermittent fasting, chicken broth is a useful tool, but it's important to understand how its calorie content affects these plans.
- Keto and Low-Carb Diets: Chicken broth is a staple in ketogenic diets because it is very low in carbohydrates and helps replenish electrolytes, which can be thrown off by the diet's restrictive nature. It provides a savory, low-carb liquid for hydration and satisfaction.
- Intermittent Fasting: While any caloric intake technically 'breaks a fast,' the low-calorie nature of chicken broth means it won't cause a significant insulin response. Some intermittent fasting experts consider a small amount of broth acceptable to stave off hunger and replenish minerals, especially during longer fasting windows.
Nutritional Benefits Beyond the Calorie Count
Even though it has a small calorie count, chicken broth is not nutritionally empty. It contains valuable components that offer health benefits:
- Hydration: As a liquid, broth is excellent for maintaining hydration, which is crucial for overall health and is especially beneficial when sick. The electrolytes, like sodium and potassium, can help replenish fluids lost due to sweating or illness.
- Gut Health: Chicken broth, particularly bone broth, contains beneficial amino acids like glutamine and glycine that can support and soothe the digestive tract.
- Immune Support: It provides vitamins and minerals that can bolster the immune system, which is why it has been a traditional remedy for colds and flu. Research also indicates chicken broth can have anti-inflammatory effects.
- Satiety: The small amount of protein in broth can contribute to a feeling of fullness, which can be beneficial for weight management by curbing hunger between meals.
Conclusion
In summary, the notion that chicken broth has zero calories is a myth. While it is not calorie-free, its extremely low energy content, coupled with its hydrating and nutritional benefits, makes it an excellent addition to a healthy diet. Whether homemade or store-bought, chicken broth offers more than just a savory taste; it provides minerals, electrolytes, and amino acids that support hydration, gut health, and immune function. For those managing calorie intake for weight loss, keto, or fasting, chicken broth is a smart, low-impact choice, provided you consider the small caloric contribution and opt for lower-sodium versions when possible.

Can Chicken Broth Help You Lose Weight?
Yes, chicken broth can support weight loss, but it is not a magic solution. It is low in calories but can promote satiety due to its protein and fluid content, helping to reduce overall calorie intake. Replacing higher-calorie meals with a cup of broth can help create the necessary calorie deficit for weight loss.
How Is Bone Broth Different from Chicken Broth?
The key difference is the simmering time and the resulting nutrient profile. Bone broth is simmered for much longer, sometimes for over 24 hours, to extract more protein, collagen, amino acids, and minerals from the bones. This results in a more nutrient-dense, and often higher-calorie, liquid than standard chicken broth.
Can I Drink Chicken Broth While Intermittent Fasting?
Technically, any amount of calories will break a true fast, and chicken broth does contain a small number of calories. However, many people who practice intermittent fasting do consume small amounts of plain chicken broth to help manage hunger and replenish electrolytes without causing a significant insulin response.
Is Low-Sodium Chicken Broth Lower in Calories?
Not necessarily. The low-sodium label refers to the salt content, not the calories. The calorie count is determined by the macronutrients (protein, fat, carbs) and can vary based on other ingredients. However, low-sodium broth is a healthier choice for those monitoring their sodium intake, especially if they have blood pressure concerns.
