Weight-loss soups often sound restrictive or bland. This oat soup for weight loss proves the opposite. It’s warm, light, and genuinely satisfying, without turning into porridge or diet food.
The idea is simple: use just enough oats to create structure, and a lot of liquid to keep volume high and calories low. When cooked the right way, it calms hunger without weighing you down.
The most important part happens at STEP 2. That’s what keeps the soup fluid instead of thick.

Utensils
- 1 medium saucepan with lid
- 1 wooden spoon
- 1 measuring cup
- 1 bowl
Ingredients (1 serving)
- 20 g rolled oats
- 400 ml water or light vegetable broth
- ½ small onion, finely chopped
- ½ carrot, finely diced
- Salt and pepper to taste
- Optional herbs such as parsley or thyme
Preparation
STEP 1
Bring the water or broth to a gentle boil in a saucepan. Add the onion and carrot. Simmer for 5 minutes.
STEP 2
Add the oats and reduce heat to low.
👉 This is crucial: low heat prevents the oats from thickening too fast.
STEP 3
Cook for 5 minutes, stirring occasionally, until the oats are tender but the soup stays fluid.
STEP 4
Season lightly with salt and pepper. Serve warm.

Why this works:
Using a small amount of oats provides fiber and satiety without excess calories. Plenty of liquid keeps the soup light and volumizing, which helps with fullness.
FEATURED TOOL
I recommend a medium saucepan with a lid to control heat and evaporation. This helps the oats cook gently and keeps the soup light instead of dense, which is essential for a weight-loss-friendly result.
