Key Terms Explained
| Term | Explanation | Why it matters here |
|---|---|---|
| Gelatin | Gelatin is a protein derived from collagen. When mixed with water and cooled, it forms a solid, jelly-like substance. | Gelatin is what gives these cups their signature jello texture; without it, it would just be flavored juice. |
| TDEE | TDEE stands for Total Daily Energy Expenditure. It’s the number of calories your body burns in a day based on your activity level. | Knowing your TDEE helps you understand how these jello cups fit into your overall calorie needs for weight management. |
| Lipogenesis | Lipogenesis is the metabolic process where your body converts excess carbohydrates into fat for storage. | Consuming large amounts of simple carbs like those in this dessert, *especially* with high fat foods, can contribute to fat storage via lipogenesis. |
