Reduced-calorie mayo still has 333 kcal per 100 g. The term "reduced" means 25% less than regular, not low-calorie – a tablespoon (15 g) still adds 50 calories. Condiments are omitted from food logs 1–80% of the time (Whitton et al., Adv Nutr 2022). Always log the specific variant.
How should I track Mayonnaise, reduced-calorie or diet, cholesterol-free?
Small amounts of Mayonnaise, reduced-calorie or diet, cholesterol-free 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.
