Key Ingredients for a Soup That Burns Fat & Keeps You Full

Ingredients (Serves 4, ~300g per bowl)

  • 1 tbsp olive oil (15ml) – Healthy fats for satiety

  • 1 onion (100g), diced – Natural sweetness & fiber

  • 3 garlic cloves (9g), minced – Boosts metabolism

  • 2 carrots (150g), chopped – Low-calorie crunch

  • 1 zucchini (200g), diced – High water content

  • 1 can diced tomatoes (400g) – Rich in lycopene

  • 1 cup red lentils (200g), rinsed – 18g protein per cup

  • 4 cups vegetable broth (950ml) – Low-sodium preferred

  • 1 tsp cumin (2g) – Aids digestion

  • 1 tsp turmeric (2g) – Anti-inflammatory

  • Salt & pepper to taste

  • Fresh parsley (10g), chopped (garnish)

Step-by-Step Guide to Making the Perfect Weight-Loss Soup

1. How to Sauté Aromatics for Maximum Flavor

Heat olive oil in a large pot over medium heat. Add onion and garlic, sautéing for 3 minutes until fragrant. This builds a flavor base that makes the soup irresistible.

2. How to Cook Lentils for Perfect Texture

Stir in carrots, zucchini, lentils, cumin, and turmeric. Cook for 2 minutes to toast the spices. Then add diced tomatoes and broth.

Pro Tip: Rinse lentils thoroughly to prevent bitterness.

3. How to Simmer for Optimal Nutrient Retention

Bring to a boil, then reduce heat to low. Cover and simmer for 20 minutes—just until lentils are tender but not mushy. Overcooking destroys nutrients!

4. How to Adjust Seasonings Like a Chef

Taste and add salt & pepper as needed. For extra richness, stir in a splash of lemon juice before serving.

5. How to Serve for Best Weight-Loss Results

Ladle into bowls and top with fresh parsley. Pair with a slice of whole-grain bread for a complete meal.
