So, you're looking at that mason jar of murky, gelatinous liquid in your fridge and wondering if it’s actually a weight-loss miracle or just overpriced soup water. Honestly, everyone talks about the collagen and the "glow," but when it involves a bone broth calorie count, things get weirdly confusing. People assume it’s basically zero calories because it looks like water. It isn't. Not even close. If you’re sipping on a cup of high-quality, long-simmered beef bone broth, you might be looking at 80 calories, whereas a thin, store-bought chicken version might barely hit 35.
That’s a huge range.
If you're tracking macros or trying to stay in a deficit, that's the difference between a light snack and a rounded-off meal addition. It matters.
The complexity of bone broth calorie density comes down to one thing: protein. Specifically, collagen. When you simmer marrow bones, knuckles, and patellas for twenty-four hours, you aren't just flavoring water; you are physically breaking down connective tissue into gelatin. That gelatin is protein. Protein has four calories per gram. Therefore, the thicker and more "jiggly" your broth is when it’s cold, the higher the calorie count is going to be. It’s a direct correlation. If your broth stays liquid in the fridge, it’s low calorie because it’s mostly just water and sodium. If you can practically cut it with a knife, it’s a nutritional powerhouse, but it’s definitely going to show up on your tracking app.
Why Your Bone Broth Calorie Count Varies So Much
You've probably noticed that no two brands have the same label. Take Kettle & Fire versus a generic store brand like Swanson. A standard 1 cup serving of Kettle & Fire Beef Bone Broth usually hovers around 40 to 50 calories. However, if you go to a local butcher or a craft kitchen where they use a high bone-to-water ratio, you could easily see 70 to 90 calories per cup.

Why? Fat content.
Most commercial brands are incredibly diligent about skimming the fat cap off the top of the vat. Fat is nine calories per gram. If a producer leaves even a small amount of that yellow "liquid gold" tallow or schmaltz in the broth, the calories spike. Many home cooks prefer to leave some fat in for the flavor—and honestly, for the vitamins—but it turns a "light" drink into something much more substantial.
The Protein Factor
Every gram of protein counts. A high-quality broth should have between 6 and 12 grams of protein per cup.
- Low Protein Broth: 3g protein = roughly 15-20 calories.
- Medium Protein Broth: 7g protein = roughly 30-45 calories.
- High Protein Broth: 10g+ protein = 50-80+ calories.
It’s actually pretty simple math once you look at the lab results. Dr. Cate Shanahan, a noted metabolic health expert, often points out that the glycine found in this protein is what helps with metabolic health, but you can’t get that glycine without the calories that come attached to the protein chain. You just can't.
The "Hidden" Calories in Your Mug
Are you just drinking it straight? Or are you doing what most people do and "upgrading" it? This is where the bone broth calorie math gets messy.
I’ve seen people add a tablespoon of grass-fed butter or MCT oil to their morning broth. Suddenly, your 45-calorie healthy snack is a 180-calorie fat bomb. That’s fine if you’re doing Keto, but if you’re just trying to bridge the gap between lunch and dinner, you might be accidentally sabotaging your deficit. Even adding a splash of coconut aminos or a bit of miso paste adds sugars and fermentation byproducts that nudge those numbers up.
Then there’s the sodium. While salt doesn't have calories, it does cause water retention. If you step on the scale after a day of heavy broth sipping and see the number went up, it’s not fat. It’s just the 1,500mg of sodium holding onto water.
Beef vs. Chicken vs. Turkey
Interestingly, beef bones tend to produce a more caloric broth than chicken. Beef bones are denser and contain more marrow. Marrow is pure fat. Even after skimming, beef broth often retains a richer profile. Chicken bone broth is typically lighter and more "accessible" for people who aren't used to the heavy, earthy taste of bovine bones. If you're looking for the absolute lowest bone broth calorie option, reach for a chicken version that has been well-strained.
Is It Actually Good for Weight Loss?
Basically, yes. But not because it's magic.
It works because of satiety. There was a study published in the journal Appetite that looked at how soup affects hunger. They found that liquids containing protein and high levels of umami (that savory taste) are significantly more satiating than plain water or even some solid foods. When you drink a 50-calorie cup of bone broth, your brain registers "food" because of the amino acid profile. You feel full.
You’re replacing a 300-calorie latte or a 200-calorie bag of chips with something that has 50 calories. That's a 150-calorie win. Over a week, that's over 1,000 calories saved. That is how bone broth "causes" weight loss. It’s a tool for displacement.
However, don't fall for the "bone broth fast" traps without understanding the math. If you're only consuming 400 calories a day via broth, you're in a massive caloric deficit. You'll lose weight, sure, but you're also losing muscle mass because, while broth has protein, it isn't a complete protein. It lacks certain essential amino acids like tryptophan. You cannot live on it alone.
What to Look for on the Label
Don't just trust the front of the box. Marketing is loud; labels are quiet.
- Check the ingredient list first. If the first ingredient is "Chicken Base" or "Yeast Extract," put it back. That’s just salty water flavored to taste like broth.
- Look for "Protein" grams. If it says 0g or 1g of protein, it isn't bone broth. It's stock. Real bone broth must have at least 6g to 9g to be worth your time.
- Scan for "Added Sugars." Some brands add cane sugar or fruit juice concentrates to balance the bitterness of over-boiled bones. This is a sneaky way the bone broth calorie count creeps up.
Making It at Home: The Calorie Control Method
If you make it yourself, you have total control. Roast your bones first—this renders out a lot of the heavy fat before you even start the water simmer.
After you've cooked your broth for 12 to 24 hours, strain it and put it in the fridge overnight. The next morning, you'll see a white, hard layer on top. That’s the fat. If you scrape that off, you've just dropped the calorie count of your broth by about 50%. What's left underneath is the protein-rich gelatin.
This home-brewed version is usually the best quality. It hasn't been watered down for profit margins. You’re getting the maximum amount of proline and hydroxyproline (the stuff that actually helps your joints and skin) for the lowest possible caloric investment.
Moving Forward with Your Goals
To get the most out of bone broth without blowing your calorie budget, treat it as a strategic tool rather than a free-for-all beverage.

- Switch your afternoon snack. Instead of reaching for processed carbs, have one cup of beef bone broth with a pinch of sea salt and some cracked pepper.
- Use it as a base. Instead of cooking rice or quinoa in water, use a lower-calorie chicken bone broth. It adds protein to the grain and makes it taste way better.
- Watch the additives. If you're at a "broth bar," be wary of the added fats like butter or oils that can quadruple the calorie count in seconds.
- Prioritize gelatin. If your broth doesn't turn into a jelly-like substance when cold, it's missing the protein density you're paying for.
Focus on the protein-to-calorie ratio. If a cup has 50 calories and 10 grams of protein, that is an elite-tier health food. If it has 50 calories and 2 grams of protein, it’s just expensive water. Check your labels, skim your home-cooked fats, and use it to stay full between your actual meals.
