When you're on a keto diet, every bite counts. Snacks need to be low in carbs, high in fat, and satisfying enough to keep you from reaching for bread or chips. That’s where olives come in. They’re salty, crunchy, and packed with flavor-but are they really keto? Let’s cut through the noise and find out.
How many carbs are in olives?
Not all olives are created equal. A single green olive (about 4 grams) has roughly 0.1 grams of net carbs. That means a small handful-say, 10 olives-comes in at under 1 gram of net carbs. Black olives are slightly higher, averaging 0.3 grams per olive, so 10 of those would be around 3 grams. That’s still low enough to fit comfortably in most keto plans.
But here’s the catch: olives are often packed in brine with added sugar or flavorings. Some brands sneak in dextrose, corn syrup, or even honey to make them taste better. Always check the label. If sugar is listed within the first three ingredients, skip it. Stick to plain, salt-only olives. You’ll find them in the refrigerated section near pickles or in jars labeled "no additives."
Why olives work on keto
Olives are mostly fat. About 80% of their calories come from monounsaturated fat-the same heart-healthy kind found in olive oil. That’s why they’re a staple in the Mediterranean diet, which shares a lot of principles with keto. A 100-gram serving (roughly 70 olives) has about 115 calories, 10.7 grams of fat, and only 6.3 grams of carbs (with 3.2 grams of fiber, so net carbs are just 3.1).
They’re also rich in antioxidants like oleuropein, which helps fight inflammation. And because they’re naturally high in sodium, they help balance electrolytes-a common issue for people starting keto. Cramps? Headaches? A few olives might be the fix you didn’t know you needed.
How to eat olives on keto
Don’t just snack on them plain. Olives are one of the most underrated keto ingredients. Try these simple ideas:
- Chop them into a salad with feta, cucumber, and olive oil dressing.
- Stir them into scrambled eggs with spinach and goat cheese.
- Use them as a topping for keto pizza instead of pepperoni.
- Blend them into a tapenade with capers, garlic, and lemon zest-spread it on celery sticks or low-carb crackers.
- Wrap them in thin slices of prosciutto for a no-cook appetizer.
These aren’t just ideas-they’re meals people in Brighton, where I live, actually eat. You’ll find olives in nearly every local deli and market, often sold in bulk by weight. That’s the best way to control what you’re buying.
Olives vs other keto snacks
Let’s compare olives to other popular keto snacks:
| Snack | Net Carbs | Fat Content | Electrolytes |
|---|---|---|---|
| Olives (green) | 0.5g | 4.5g | High sodium |
| Almonds (raw) | 2.5g | 14g | Moderate magnesium |
| Macadamia nuts | 1.5g | 21g | Low |
| Cheese (cheddar) | 0.4g | 9g | High calcium |
| Beef jerky (sugar-free) | 3g | 1g | High sodium |
Olives beat almonds and jerky on carb count and come close to cheese. But unlike cheese or nuts, they’re low in protein-which matters if you’re trying to limit protein on keto. Too much protein can kick you out of ketosis. Olives? Pure fat, minimal protein, almost no sugar. That’s the sweet spot.
Pitfalls to avoid
Not all olives are keto-friendly. Watch out for:
- Stuffed olives-especially those with blue cheese, jalapeños, or almonds. The fillers often add hidden carbs.
- Marinated olives with honey, maple syrup, or balsamic glaze. Even a little sugar adds up.
- Pre-packaged snack packs with olives mixed with dried fruit or crackers. The olives might be fine, but the rest isn’t.
Stick to plain, single-ingredient olives. If you’re unsure, go for Kalamata or green Castelvetrano olives-they’re usually packed in just brine and olive oil.
Can you eat too many olives?
Technically, yes. They’re high in sodium. If you’re salt-sensitive or have high blood pressure, overdoing it could be a problem. A cup of olives has around 1,000 mg of sodium-that’s nearly half the daily limit for some people. But for most on keto, that’s not an issue. In fact, many need extra sodium.
Also, olives are calorie-dense. One cup is about 150 calories. If you’re trying to lose weight, count them. But if you’re just maintaining or using them as a snack between meals? Go ahead. They’re far better than a protein bar with 8 grams of sugar.
Final verdict
Yes, olives are keto. Plain, unadulterated olives are one of the most underrated keto foods out there. They’re low in net carbs, high in healthy fats, rich in electrolytes, and incredibly satisfying. You can eat them raw, cook with them, or use them as a flavor boost in almost any dish.
Just keep it simple: no sugar, no additives, no nonsense. Buy them by the jar, not the snack pack. And if you’re craving something salty and rich? Reach for the olives. Your body will thank you.
Are green olives better than black olives for keto?
Both are keto-friendly, but green olives have slightly fewer net carbs-about 0.1 gram per olive versus 0.3 gram for black olives. The difference is small, so choose based on taste. Green olives are more bitter and briny; black olives are milder and slightly sweeter. Just avoid any with added sugar in the ingredients.
Can I eat olives every day on keto?
Yes, if you’re mindful of portion size and sodium. A small handful (10-15 olives) daily is perfectly fine for most people on keto. They’re a great source of healthy fats and can help curb cravings. If you’re watching sodium closely, limit intake to 5-8 olives per day and balance with water and potassium-rich foods like avocado or spinach.
Do stuffed olives have more carbs?
It depends on the stuffing. Olives stuffed with cheese or garlic usually add less than 0.5g net carbs. But those stuffed with almonds, dates, or apples can add 2-5g per olive. Always check the label. If the stuffing includes fruit, sugar, or flour, skip it. Stick to plain or cheese-stuffed.
Are canned olives okay for keto?
Yes, if they’re packed in brine or olive oil with no added sugar. Avoid cans that list "sugar," "dextrose," or "high-fructose corn syrup" in the ingredients. Look for brands that use just olives, water, salt, and maybe olive oil. Glass jars are often better than cans because they’re less likely to have hidden additives.
Do olives help with keto flu?
Yes. Keto flu symptoms-headaches, fatigue, cramps-are often caused by electrolyte loss. Olives are naturally high in sodium, which helps replenish what’s lost when you cut carbs. Pair them with magnesium-rich foods like pumpkin seeds or spinach, and drink plenty of water. A small bowl of olives can be a simple, tasty fix.
