Ingredients Overview

Protein-Enhanced Gelatin
- Unflavored gelatin (1–2 tbsp): Provides structure; easy to dissolve in liquid.
- Whey protein isolate or collagen peptides (1/4 cup or 25–30 g): Adds post-op protein without compromising texture.
- Hot water (1 cup / 240 ml): Needed to dissolve gelatin completely.
Sweetener
- Stevia, monk fruit, or erythritol (to taste): Low-calorie, bariatric-friendly sweetener. Avoid sugar or honey in early post-op phases.
Flavorings and Add-ins
- Fruit puree (2–4 tbsp, optional): Use soft, low-sugar fruits like berries or mango.
- Vanilla extract (1 tsp, optional): Adds depth to unflavored gelatin.
- Cocoa powder (1 tsp, optional): For chocolate-flavored gelatin.
Optional Toppings (for later phases)
- Greek yogurt (low-fat, 1–2 tbsp): Adds extra protein and creaminess.
- Soft fruit pieces: Such as berries, kiwi, or melon—introduced gradually according to your bariatric diet stage.
- Cinnamon or nutmeg: For extra flavor without sugar.
Step-by-Step Instructions
Step 1: Dissolve the Gelatin
Pour 1 cup of hot water into a bowl. Sprinkle gelatin over the surface and let it bloom for 2–3 minutes. Stir until completely dissolved, ensuring no clumps remain.
Step 2: Mix in Protein
Add whey protein isolate or collagen peptides to the gelatin mixture. Stir thoroughly to create a smooth, uniform consistency. If the mixture becomes slightly thick, add 1–2 tablespoons of warm water to help it dissolve evenly.
Step 3: Sweeten and Flavor
Add your chosen sweetener gradually, tasting as you go. Stir in optional flavorings like vanilla extract, cocoa powder, or a small amount of fruit puree for natural sweetness and flavor.
Step 4: Pour into Molds
Pour the mixture into silicone molds, small ramekins, or a shallow dish for easy portioning.
Step 5: Chill
Refrigerate for 2–4 hours or until fully set. Gelatin should be firm but tender.
Step 6: Serve
Serve plain, or top with a dollop of Greek yogurt or soft fruit pieces. Cut into small, manageable portions suitable for post-bariatric eating guidelines.
Flavor and Texture

The combination of gelatin and protein powder creates a dessert that is satisfying, nutritionally beneficial, and gentle on the digestive system.
- Texture: Smooth, tender, and slightly wobbly, easy to chew and swallow.
- Flavor: Naturally mild; sweeteners and flavorings can be customized.
- Mouthfeel: Creamy if yogurt is added, slightly firm if pure gelatin is used.
Tips for the Perfect Bariatric Gelatin
- Use high-quality protein: Whey isolate or collagen peptides work best for smooth texture. Avoid protein powders with additives that can affect setting.
- Avoid overheating protein: Add protein after gelatin is dissolved in hot water, not boiling water, to prevent clumping.
- Sweeten gradually: Start with small amounts of low-calorie sweeteners and adjust to taste.
- Add flavorings carefully: Strong flavors like cocoa or fruit puree enhance taste but should not compromise the gelatin’s ability to set.
- Check consistency: Gelatin should be firm enough to hold shape but soft enough for easy swallowing.
