- 1.
Use fresh lime juice instead of dressings or sauces — squeezing half a lime over a dish adds only ~5 calories versus 50–100+ in a tablespoon of most dressings.
- 2.
Add lime zest for intense citrus flavor with essentially zero calories — the zest contains no measurable caloric content.
- 3.
Infuse water with lime slices to make plain water more appealing without adding significant calories (a full slice is just ~4 calories).
- 4.
Use lime juice to brighten low-calorie salsas, slaws, and grain bowls, adding flavor complexity without reaching for high-calorie condiments.
- 5.
Whole lime segments contribute fiber (2.8g per 100g), which supports satiety — eating the fruit rather than just juicing it maximizes this benefit.
