Oat Milk vs Almond Milk: Calories, Nutrition & Which Is Better?
CalorieMetrica’s database does not yet include a dedicated Oat Milk entry, so this page uses Low Fat Milk as the closest verified stand-in for illustrating typical calorie and macro ranges, alongside Almond Milk’s real database values. In the real world, unsweetened oat milk usually runs a little higher in calories and carbs than unsweetened almond milk, with almost no protein in either — almond milk is generally the lower-calorie pick, oat milk the creamier, more coffee-friendly one.

Values marked with * come from CalorieMetrica’s Low Fat Milk entry, used only as a directional, verified-database stand-in because CalorieMetrica does not yet have a dedicated Oat Milk entry — these are not oat-milk-specific figures. Almond Milk values are the real database entry, also used by the Food Compare tool and Meal Planner. For an oat-milk purchase decision, always check the exact brand’s nutrition label — commercial unsweetened oat milk commonly runs 90–130 kcal per cup with 2–3g protein and 16–20g carbs, noticeably more than almond milk.
Calories: oat milk vs almond milk
Because CalorieMetrica’s database does not yet carry a dedicated Oat Milk entry, we cannot give you an exact verified oat milk number the way we can for almond milk. What we can say confidently, from how these drinks are made, is the general pattern: oats are a starchy grain, so oat milk almost always carries more natural carbohydrate and slightly more calories per cup than almond milk, which is mostly water with a small amount of ground almonds.
Unsweetened almond milk in CalorieMetrica’s database runs about 17 kcal per 100ml, or roughly 41 kcal per 240ml cup — one of the lightest milk options available. Typical commercial unsweetened oat milk brands report 90–130 kcal per cup on their own labels, so expect oat milk to cost you meaningfully more calories per cup if you drink it daily, even in "unsweetened" form.
Nutrition comparison
Both drinks are naturally low in protein compared to dairy or soy milk. Oat milk typically edges out almond milk slightly on protein (often 2–3g per cup on real labels) and carries noticeably more carbohydrate from the oat starch, while almond milk stays lower on both fronts and contributes a small amount of fiber and unsaturated fat from the almonds.
Fortification varies enormously by brand for both drinks — many oat and almond milks are fortified with calcium, vitamin D and vitamin B12 to roughly match dairy milk, but "barista" versions of either often add oil for creaminess, raising the fat and calorie count above the standard "original" or "unsweetened" cartons. Always compare the actual nutrition panel on your specific brand rather than assuming; see the Protein Calculator if protein from your milk choice matters to your day.
Which is better for weight loss?
Almond milk, on the numbers CalorieMetrica can verify — its 41 kcal per cup is hard to beat among plant milks. Oat milk can still fit a weight-loss plan comfortably; it simply tends to cost more calories per cup, so if you drink several cups a day in coffee, that difference adds up. Check your own carton: some "light" or "skinny" oat milk lines are formulated closer to almond milk’s calorie range. Plan your day with the TDEE Calculator and Meal Planner.
Which is better for muscle gain?
Neither is a strong protein source, but oat milk’s slightly higher natural protein and carbohydrate content gives it a small edge for pure calorie and carb volume around training. Neither replaces a real protein source — pair either milk with whey, Greek yogurt, eggs or chicken to hit your target. Check your needs with the Protein Calculator.
Which is healthier overall?
This is genuinely a personal-fit decision rather than one drink being objectively healthier. If you are watching total calories or carbs closely, almond milk’s verified low numbers make it the safer everyday default. If you have a tree nut allergy, prefer a creamier coffee texture, or want a naturally cholesterol-free option with a milder taste, oat milk (check for certified gluten-free oats if needed) is a reasonable pick.
Both are commonly fortified to help close the calcium and vitamin D gap left by skipping dairy — check the label on your specific carton rather than assuming either is automatically "healthier" by default.
Practical meal examples
Weight-loss plate (~150 kcal): black coffee with a splash of unsweetened almond milk (~41 kcal) + a slice of whole wheat toast (~90 kcal).
Muscle-gain plate (~400 kcal): oat milk latte (~110 kcal, brand-dependent) + a protein bar (~200 kcal) + banana (~90 kcal).
Balanced daily plate (~200 kcal): bowl of oats made with almond milk instead of dairy, keeping the meal light while still creamy.

FAQs: oat milk vs almond milk
Which has fewer calories, oat milk or almond milk?
Unsweetened almond milk is usually the lower-calorie choice, at roughly 41 calories per cup in CalorieMetrica’s verified database. Commercial unsweetened oat milk typically runs higher, around 90–130 calories per cup depending on the brand — always check your specific carton’s label.
Why doesn’t CalorieMetrica have an exact Oat Milk entry?
CalorieMetrica’s database is still expanding. This page uses a verified dairy-based entry as a directional stand-in to illustrate typical ranges honestly, rather than inventing an oat milk number. Check your product’s nutrition label for exact figures.
Which has more protein, oat milk or almond milk?
Oat milk typically has slightly more protein than almond milk on most commercial labels (often 2–3g per cup versus roughly 1g for almond milk), though neither is a meaningful protein source on its own.
Is oat milk better for weight loss than almond milk?
Usually not — unsweetened almond milk tends to be lower in calories and carbohydrates than oat milk. Oat milk can still fit a weight-loss diet in reasonable amounts; just factor in the extra calories if you drink several cups a day.
Can I use oat milk or almond milk in coffee?
Yes, both work well in coffee. Oat milk is popular for lattes and cappuccinos because its starch content froths and steams more like dairy milk. Almond milk works fine in black coffee or tea but froths less smoothly.
Which is better for nut allergies or gluten sensitivity?
Almond milk is unsuitable for tree nut allergies; oat milk should be avoided or chosen carefully (certified gluten-free) by people with gluten sensitivity or celiac disease, since standard oats can be cross-contaminated with wheat.
