19 Low Calorie Overnight Oats for Weight Loss
Let’s be honest — mornings are rough. The last thing you want to do is stand in the kitchen at 7 AM trying to figure out what to eat that won’t wreck your calorie goals. That’s exactly why overnight oats changed my life. You prep them the night before, wake up, grab them from the fridge, and actually eat something nourishing without the morning drama. And when you’re working on weight loss? These little jars are basically your best friend.
I’ve been making overnight oats for years, and I’m not exaggerating when I say they’ve made sticking to a healthy routine so much easier. So here are 19 low calorie overnight oats for weight loss that actually taste good — not like cardboard soaked in water 🙂
Why Overnight Oats Work for Weight Loss
Before we get into the recipes, let’s talk about why overnight oats are such a smart move when you’re trying to lose weight.
Oats are high in fiber, specifically a type called beta-glucan, which slows digestion and keeps you full for hours. When you’re not hungry by 10 AM, you’re less likely to raid the snack drawer. That’s a win.
They’re also incredibly easy to portion control. You make them in individual jars, so you always know exactly what you’re eating. No guesswork, no “oh I’ll just have a little more” situations.
And here’s the best part — most of these recipes clock in between 250 and 400 calories, which leaves plenty of room in your daily intake for satisfying meals the rest of the day. If you’re also looking to keep your other meals just as balanced, these low calorie vegan meals for weight loss pair brilliantly with a morning oat routine.
The Base Recipe You Need to Know
Every single overnight oat recipe starts from the same simple base. Master this, and you can customize endlessly.
Basic base (per serving):
- ½ cup rolled oats (not instant — they get too mushy)
- ½ cup unsweetened almond milk or any dairy-free milk you prefer
- ¼ cup plain non-fat Greek yogurt
- 1 tsp chia seeds
- Sweetener of choice (optional)
Mix, seal, refrigerate overnight. That’s it. No cooking, no fuss.
19 Low Calorie Overnight Oat Recipes
1. Classic Banana and Cinnamon Oats
This is the one I make when I want something comforting and simple. Mash half a ripe banana into your base, add a generous pinch of cinnamon, and top with a few banana slices in the morning.
Approx. calories: 280
The natural sweetness of the banana means you don’t need any added sugar. Cinnamon also helps regulate blood sugar levels, which IMO makes this one of the smartest low calorie overnight oats you can start with.
2. Blueberry and Vanilla Oats
Blueberries are low in calories but high in antioxidants, which is basically the dream combo. Stir ¼ cup fresh or frozen blueberries into your base along with ½ tsp vanilla extract.
Approx. calories: 265
They get jammy and soft overnight, which gives the oats a naturally sweet, fruity flavor without adding a single gram of refined sugar.
3. Strawberry Cheesecake Overnight Oats
Yes, you read that right. Cheesecake-flavored oats under 350 calories. Mix 2 tbsp light cream cheese into your base, add ½ tsp vanilla, then top with sliced strawberries in the morning.
Approx. calories: 340
This one is great when you’re craving something indulgent but don’t want to blow your goals. It feels like a treat, but it’s actually a solid, balanced breakfast.
4. Apple Pie Overnight Oats
Dice up half a small apple, mix it into your base with ½ tsp cinnamon, a pinch of nutmeg, and a tiny drizzle of maple syrup. The oats soak up all those spiced apple flavors overnight.
Approx. calories: 300
This one is perfect for fall mornings, but honestly, apples are available year-round so there’s no reason to wait.
5. Peanut Butter and Banana Oats
Combine 1 tbsp natural peanut butter with a mashed banana in your base. Top with a few slices of banana and a sprinkle of dark chocolate chips if you’re feeling fancy.

The peanut butter adds healthy fat and protein, which keeps you fuller longer. Just make sure you’re using natural peanut butter without added sugar or oils.

Because sometimes you just need chocolate for breakfast — no shame in that. Add 1 tbsp unsweetened cocoa powder and 1 tbsp natural peanut butter to your base. Sweeten lightly with a little honey or stevia.
Approx. calories: 355
This tastes like dessert for breakfast, but the cocoa is rich in antioxidants and the oats keep your energy steady all morning.

This one transports you to somewhere warmer and sunnier, even if you’re eating it at your kitchen table in January. Highly recommend.
8. Peach and Ginger Oats
Dice half a ripe peach and mix it into your base with ¼ tsp freshly grated ginger. Ginger is fantastic for digestion and metabolism, so this one is a solid weight loss choice.
Approx. calories: 270
If peaches aren’t in season, frozen diced peaches work perfectly. Don’t let “fresh produce only” thinking hold you back.
9. Lemon Blueberry Oats
Add the zest and juice of half a lemon to your base, then fold in ¼ cup blueberries. The lemon brightens everything up and gives the oats a refreshing, almost summery vibe.

12. Cherry Almond Oats
Mix ¼ cup pitted, halved cherries (fresh or frozen) into your base with ¼ tsp almond extract and a small handful of sliced almonds.

It tastes like a cherry bakewell in oat form. Cherries are also high in compounds that support sleep quality, so eating them regularly is a double bonus.

Stir ¼ cup raspberries into your base and add a few dark chocolate chips (aim for 70% cacao or higher). The tartness of raspberries and the bitterness of dark chocolate balance each other beautifully.
Approx. calories: 310

Tips for Making the Best Low Calorie Overnight Oats
Now that you’ve got 19 recipes to work with, here are a few practical tips to make sure your oats turn out great every single time.
Use rolled oats, not instant. Instant oats get too soft and lose their texture overnight. Rolled oats hold up perfectly.
- Always seal your jar tightly — oats dry out in the fridge if left uncovered
- Add toppings in the morning — fresh fruit and crunchy toppings go on right before eating, not the night before
- Prep multiple jars at once — Sunday prep for the whole week makes mornings effortless. If batch cooking is your thing, these plant-based meal prep ideas will give you even more inspiration
- Thin with a splash of milk in the morning if the oats thicken too much overnight
- Taste before sweetening — you’ll often find the oats are naturally sweet enough
FYI, overnight oats keep well in the fridge for up to five days, so there’s genuinely no excuse not to prep ahead.
How to Keep the Calories Low Without Sacrificing Flavor
Here’s where people go wrong. They start with a solid low calorie overnight oats recipe, then pile on granola, nut butter, honey, and banana slices until the jar is sitting at 600+ calories. Sound familiar?
The key is being intentional with your toppings. Fruit adds natural sweetness with minimal calories. A teaspoon of nut butter adds fat and protein, but a full tablespoon doubles those numbers fast. Sweeteners like honey or maple syrup add up quickly — if your fruit is ripe and sweet, you often don’t need any at all.
Stick to the portions in the recipes above and you’ll stay comfortably in that 250–400 calorie range that makes overnight oats such an effective tool for weight loss.
Pairing Your Oats with a Balanced Day
Overnight oats handle breakfast beautifully, but weight loss happens across your whole day. If you want your mornings to set the tone for the rest of your meals, it helps to have equally easy and satisfying options lined up.
For lunch, these high protein vegan meals are brilliant at keeping hunger in check through the afternoon. And for those mid-afternoon moments when your stomach starts complaining, a smart snack from a list of healthy and satisfying vegan snacks can save you from making impulsive food choices before dinner.
The point is — weight loss doesn’t have to mean misery. It just means making consistent, satisfying choices throughout the day.
Final Thoughts
There you have it — 19 low calorie overnight oats for weight loss that actually deliver on taste. No bland, boring breakfasts. No complicated prep. Just a jar in the fridge waiting for you every morning, doing all the hard work while you sleep.
The best recipe is the one you actually eat consistently, so start with two or three of these that sound most appealing to you. Build the habit first, then experiment with new flavors once it becomes second nature.
Honestly? The hardest part is remembering to prep them the night before. After that, mornings get a whole lot easier — and your waistline will thank you for it.
