Light mayo has 238 kcal and 22 g fat per 100 g. "Light" means at least one-third fewer calories than regular, but a tablespoon (15 g) still adds 36 calories. Condiments are omitted from food logs 1–80% of the time (Whitton et al., Adv Nutr 2022). One measured portion sets your visual baseline.
How should I track Salad Dressing, mayonnaise, light?
Small amounts of Salad Dressing, mayonnaise, light add up faster than most people realize. A systematic review (Whitton et al., Adv Nutr 2022) found that condiments are among the most frequently omitted items in food logs — skipped 1–80% of the time. A tablespoon of mayo or dressing can add 50–100 calories, and most people use two or three tablespoons without measuring. The fix is simple: keep a teaspoon or scale near your plate and measure once. Sauces and dressings are often the hidden reason a "healthy" salad ends up at 600+ calories.
