Both habits use the exact same underlying trick, taking in protein and volume shortly before a meal so you naturally eat less at that meal.

How They Compare
At a Glance
- Gelatin: cheaper, gels for texture, incomplete protein
- Protein powder: pricier, mixes without gelling, usually a complete protein
- Both work through the same pre-meal fullness mechanism
- Protein powder often has more calories per serving
Quick Take
Protein powder is the more nutritionally complete option. Gelatin is cheaper and lighter, a fair trade for many people.
