Portion Notes
- A 100g portion is useful for precise tracking when weighing raw meat.
- A single breast (175g) is the most common household serving — track this as one unit rather than estimating grams.
- Doubling the portion from 100g to 175g adds 124 calories, not proportionally more — calorie density remains constant at 1.65 per gram.
