You're standing in your kitchen, spoon in hand, staring at a bag of tiny black specks that look more like landscaping gravel than "superfood." You want to sprinkle them on your Greek yogurt, but you’re tracking your macros. You need to know the damage. Specifically, you're wondering about how many calories in a tablespoon of chia seeds and whether that tiny scoop is actually going to move the needle on your weight loss goals or just get stuck in your teeth.
It’s about 60.
Roughly 58 to 65 calories per tablespoon, depending on the brand and how high you heap that spoon. That might sound like a lot for something that takes up almost zero space in your bowl. But honestly, calories are the least interesting thing about these seeds. If you’re just counting the energy density, you’re missing the entire point of why people obsess over Salvia hispanica.
Why the Calorie Count is Deceptive
Standard nutrition labels, like those you'll find on a bag of Navitas or Bob’s Red Mill, usually list a serving as two tablespoons. That’s about 120 to 130 calories. So, when you break it down to a single tablespoon, you’re looking at that 60-calorie mark.
But here’s the kicker.
About 80% of the carbohydrates in chia seeds are actually fiber. If you look at the back of the bag, you’ll see roughly 5 grams of carbs per tablespoon, but 4 of those grams are fiber. Because your body doesn't fully digest fiber, the "net" caloric impact might actually be lower than the raw math suggests. Some researchers, including those looking at the physiology of seed digestion, suggest that if you eat the seeds whole without grinding them, you might not even absorb every single calorie tucked inside that tough outer shell.
They’re tiny tanks.
The Science of the "Chia Gel"
Have you ever left chia seeds in a glass of water for ten minutes? They turn into a weird, gelatinous blob. This isn't just a kitchen science experiment; it’s a biological superpower. Chia seeds can absorb up to 12 times their weight in liquid.

When you consume those 60 calories, they aren't just sitting there. They expand. In your stomach, that tablespoon of seeds turns into a much larger volume of gel. This is why people who add chia to their morning oats or smoothies report feeling full until lunch. You’re essentially hacking your satiety signals.
A study published in the Journal of Food Science and Technology highlighted how this mucilaginous fiber slows down the conversion of starches into sugars. This means you don't just get a calorie hit; you get a stabilized blood sugar level. No mid-morning crash. No frantic reaching for a donut at 10:30 AM.
Breaking Down the Macros Per Tablespoon
If we’re being precise, a 12-gram tablespoon usually contains:
- Calories: 58-60
- Protein: 2 grams
- Fat: 4 grams (mostly healthy Omega-3s)
- Fiber: 4-5 grams
- Net Carbs: Less than 1 gram
That fat content is mostly Alpha-linolenic acid (ALA). It’s the plant-based version of Omega-3. While it’s not as readily absorbed as the EPA and DHA you find in salmon, it’s still a heavy hitter for heart health. You’re getting a lot of nutritional "bang" for a very small caloric "buck."
What Most People Get Wrong About Serving Sizes
I’ve seen people dump a quarter cup of chia seeds into a pudding thinking it’s "free" food because it’s healthy. It’s not. A quarter cup is four tablespoons. That’s 240 calories. If you’re adding that on top of a meal that’s already 600 calories, you’ve just turned a healthy lunch into a calorie bomb.
Context matters.
If you use a tablespoon of chia to replace a tablespoon of butter or mayo, you’re winning. If you’re just adding it on top of an already caloric diet, you might see the scale creep up. It’s a dense food. Think of it more like a nut or a concentrated oil than a vegetable.

Don't Forget the Micronutrients
Beyond the how many calories in a tablespoon of chia seeds debate, there’s the mineral density. One tablespoon gives you roughly:
- About 8% of your daily Calcium.
- Nearly 15% of your Manganese.
- About 12% of your Phosphorus and Magnesium.
For a vegan or someone avoiding dairy, that calcium hit is a big deal. It’s rare to find that much mineral density in 60 calories.
Real-World Usage: Grinding vs. Whole
There’s some debate in the nutrition community—think Dr. Michael Greger or the folks over at Precision Nutrition—about whether you should grind these things.
If you eat them whole, you get the fiber benefits and the "fullness" factor. However, the Omega-3 fats are locked inside. Your teeth aren't great at cracking every single tiny seed. If your goal is heart health and inflammation reduction, pulse them in a spice grinder for three seconds before adding them to your food. If your goal is just staying full and keeping the calories low, eat them whole.
The Hydration Warning
This is important. Don't be the person who eats a dry tablespoon of chia seeds and then doesn't drink water. Because they absorb so much liquid, they can actually cause constipation or, in rare cases, an esophageal blockage if they expand before they hit your stomach.
Always mix them with something. Or drink a big glass of water right after.
Practical Ways to Use 60 Calories of Chia
You don't have to just make "pudding" which, let’s be honest, has a texture that some people find... polarizing.

- The Egg Swap: Mix 1 tablespoon of chia with 3 tablespoons of water. Let it sit. It becomes a "chia egg" for baking. It’s 60 calories compared to a large chicken egg’s 70-80, plus you get the fiber.
- Thickening Soups: Instead of using cornstarch or flour (which are empty carbs), whisk in a tablespoon of chia. It’ll thicken a watery stew without changing the flavor profile.
- Salad Topper: They add a slight crunch without the heavy calories of croutons.
- The "Internal Shower" Drink: A TikTok trend that actually has some merit (though the name is cringey). Water, lemon, and a tablespoon of chia. It’s a great way to bridge the gap between lunch and dinner.
Are There Any Downsides?
While the calorie count is low, the fiber is high. If your body isn't used to 5 grams of fiber in one sitting, your gut might complain. We’re talking bloating or gas. Start with half a tablespoon. See how you feel.
Also, they contain phytic acid. This is an "anti-nutrient" found in many seeds and nuts that can slightly inhibit the absorption of certain minerals. It’s not a dealbreaker for most people, but it’s worth noting if you have a known mineral deficiency.
Summary of the Tablespoon Stats
To keep it simple, here is the breakdown you need to remember next time you’re logging your food:
A single leveled tablespoon is roughly 12 grams. You’re looking at 60 calories. You’re getting 2 grams of protein and about 5 grams of fiber. It is one of the most nutrient-dense items in your pantry.
Compared to a tablespoon of flax seeds (55 calories) or hemp hearts (55-60 calories), chia is right in the mix. It wins on the fiber front, though hemp usually wins on the protein front.
Actionable Next Steps
If you want to incorporate chia seeds without ruining your caloric deficit, follow these three steps:
- Measure, don't eyeball: Use an actual measuring spoon. It’s very easy to accidentally pour out two tablespoons (120 calories) when you only intended for one.
- Hydrate the seeds first: Give them at least 10-15 minutes in liquid before consuming. This ensures they expand outside your body rather than drawing water out of your digestive tract.
- Watch the toppings: If you’re making chia pudding, the 60 calories of seeds isn't the problem—it’s the honey, coconut milk, and granola you add on top that turns it into a 500-calorie dessert. Use unsweetened almond milk and berries to keep the total count under 150.
Stop worrying about the 60 calories and start focusing on how that tablespoon makes you feel two hours after you eat it. If it stops you from snacking on a bag of chips later in the afternoon, those 60 calories are the best investment you'll make all day.
