Sourdough Calories & My Kitchen Story
The magic of one slice: more than just numbers
There’s something humbling about slicing into a fresh sourdough loaf, hearing the crust crackle, and watching steam rise from the center. My love for sourdough started with a messy boule and a ghosted date, but that mistake sparked something deeper. Years later, I now know the slice of sourdough bread calories can surprise you, especially if you’re trying to eat more mindfully.
So how many calories are in a slice of sourdough bread? The answer depends on how it’s made. Homemade versions using just flour, water, and salt typically have around 80 calories per slice. But some bakery or store-bought slices pack more, often reaching 100 calories. That’s why checking the slice of sourdough bread calories is smart before building your sandwich or breakfast toast.
If you’re counting calories for weight loss, understanding how many slice of sourdough bread calories you consume per day is key. Two slices might set you back 160–180 calories. But sourdough has a nutritional edge, it digests differently due to fermentation, often leading to better satiety and blood sugar balance.

Comparing Calories , Sourdough vs. Other Breads
Is sourdough lower in calories than other breads?
When you’re counting calories, it’s tempting to wonder: is sourdough bread really a lighter option? The answer might surprise you. The slice of sourdough bread calories is fairly average, not the lowest, but not the highest either. A typical medium slice comes in at around 80 to 100 calories, depending on the recipe. That’s close to whole wheat bread, which ranges from 70 to 90 calories, and lighter than some multigrain or brioche options that can hit 120 calories or more per slice.
What makes sourdough stand out isn’t just calories, it’s digestibility. Thanks to natural fermentation, sourdough bread is often easier on the stomach. The wild yeast and bacteria pre-digest some of the flour, which may lower the bread’s glycemic index. This means that even though the slice of sourdough bread calories may match other breads, it can still be a smarter choice for blood sugar control and satiety.
Whole wheat vs. white sourdough , does it matter?
Not all sourdough is created equal. If you’re choosing between white and whole wheat sourdough, opt for the latter when possible. Whole wheat sourdough tends to be higher in fiber and protein, which helps keep you fuller longer. Though the slice of sourdough bread calories might be slightly higher, around 90–100 per slice, the added nutritional benefits often outweigh the calorie bump.

So next time you’re staring down the bread aisle, remember: sourdough may not be the lightest, but it’s one of the most satisfying, and forgiving, choices you can make.
Sourdough and Weight Loss , Can Bread Fit Your Diet?
Is sourdough bread good for weight loss?
Let’s address the question everyone’s asking: is sourdough bread good for weight loss? You might think bread is off-limits, but that’s not true, especially with sourdough. While the slice of sourdough bread calories averages around 80 to 100, the fermentation process may actually help you feel fuller longer. That means you might eat less overall, even if the calorie count seems similar to other breads.
The key is how your body processes sourdough. Because it’s naturally fermented, it tends to have a lower glycemic load, which can help control hunger and energy crashes. That’s especially important if you’re watching your weight. I’ve coached many workshop students through sourdough swaps in their diets, and they’re always surprised how satisfied they feel with just one slice, especially when paired with fiber- or protein-rich toppings.
For example, topping a slice with smashed avocado, boiled eggs, or even low-fat ricotta keeps you full without blowing your calorie budget. So yes, if you’re asking whether the slice of sourdough bread calories work in a weight loss plan, the answer is a confident yes, with balance.
How to enjoy sourdough without overdoing it
Weight loss isn’t about cutting everything out, it’s about making smarter choices. One way to manage the slice of sourdough bread calories is by slicing your loaf thinner at home. Most store-bought loaves are cut thick, pushing each slice past 100 calories. At home, I slice mine about ½ inch thick and weigh it occasionally to stay mindful.
Also, timing matters. Having your sourdough slice for breakfast or lunch, when your body’s insulin sensitivity is higher, can support better energy use. Looking for smart pairing tips? Explore our avocado toast guide and protein-packed snacks for simple ideas.
So go ahead and enjoy that slice, just do it with intention, not guilt.
Sourdough Slice Calories , Types, Brands & Variations
Why calories vary between sourdough breads
Not all sourdough slices are created equal. Depending on the brand, ingredients, and baking method, the slice of sourdough bread calories can vary more than you’d expect. A rustic homemade sourdough slice (½ inch thick) usually clocks in at 75 to 90 calories, while a dense whole grain version can reach 100 to 110 calories per slice. Add seeds, nuts, or olive oil to the dough? The calories go up even more.
Even fermentation style matters. Longer fermentation can slightly reduce available starches, which may minimally impact the slice of sourdough bread calories, but more importantly, it improves gut health. Some commercial loaves use vinegar or shortcuts that skip slow fermentation, giving the sour taste without the digestive benefits.
Whether you buy it or bake it, it pays to check the nutrition label—or better yet, weigh your slice. An average sourdough slice weighs 30–35g, and you can calculate calories accordingly.
Popular brands and their calorie counts
To give you a quick snapshot, here’s a comparison of some popular sourdough brands:| Brand | Calories Per Slice |
|---|---|
| Trader Joe’s Sourdough | 90 |
| Dave’s Killer Bread Sourdough | 110 |
| Whole Foods 365 Sourdough | 100 |
