The calorie count for bone broth is not a fixed number; it's a dynamic figure influenced by several key variables. For most people, a cup of bone broth is a very low-calorie addition to their diet, but understanding the details can help with precise meal planning, especially for those on restrictive diets like keto or those counting calories for weight management.
Factors Influencing Bone Broth Calories
The total energy content of your bone broth is primarily determined by its macronutrient profile, mainly protein and fat. The carbohydrates present are typically negligible unless a significant amount of starchy vegetables are used and not strained out. The following factors play the most crucial role:
Type of Bones and Animal
- Beef Bones: Beef bone broth may contain more collagen (specifically Type III) and protein per gram. If fat is removed, a 1-cup serving can range from 30 to 45 calories.
 - Chicken Bones: Chicken bone broth can yield a high amount of Type II collagen and often falls within the 30-60 calorie range.
 
Fat Content and Removal
- Skimming the Fat: The biggest factor in calorie content is removing the fat cap after refrigeration. Fat has 9 calories per gram. Removing it can reduce a 50-75 calorie cup to 30-45 calories.
 
Preparation and Ingredients
- Homemade vs. Store-Bought: Homemade allows control over concentration and ingredients. Some store-bought options may have thickeners or higher fat.
 - Added Ingredients: Vegetables strained out have minimal caloric impact. Adding oil or butter will significantly increase calories.
 
Homemade vs. Store-Bought Bone Broth
| Feature | Homemade Bone Broth | Store-Bought Bone Broth | 
|---|---|---|
| Calorie Control | High. You can control fat content and concentration. | Low. Depends entirely on the brand's recipe. | 
| Ingredient Control | High. You know exactly what goes in. | Low. Must rely on label; some may contain additives. | 
| Flavor Profile | Customizable. Can be tailored to personal preference with herbs and spices. | Fixed. Flavor profile is set by the manufacturer. | 
| Typical Calories/Cup | 30-60 (varies based on fat skimming). | 30-60 (varies by brand and formulation). | 
| Cost | More cost-effective, especially when using leftover bones. | Can be more expensive, especially premium brands. | 
| Nutrient Density | Often higher, especially with a long simmer time and acid (like vinegar) to extract minerals. | Varies significantly. Look for labels detailing protein and collagen content. | 
| Convenience | Low. Requires time and effort for simmering. | High. Ready to heat and serve. | 
The Low-Calorie Powerhouse
Bone broth is considered a nutritional powerhouse due to its protein and amino acid content. Benefits include:
- Supports Weight Management: Protein and gelatin can promote fullness, reducing appetite.
 - Boosts Gut Health: Amino acids may help repair the gut lining and reduce inflammation. Gelatin supports digestion.
 - Aids Joint Health: Glucosamine, chondroitin, and collagen support cartilage and joint maintenance.
 - Promotes Healthy Skin: Collagen is crucial for skin elasticity, with beef broth (Type III collagen) noted for skin benefits.
 - Enhances Immune Function: Amino acids in bone broth may support the immune system with anti-inflammatory properties.
 
To make your own, combine bones, water, apple cider vinegar, and optional vegetables and herbs. Simmer for 12-24 hours. Strain and chill to easily remove fat, ensuring a low-calorie broth.
