How many calories are in 1 tablespoon of mayonnaise?

One tablespoon of mayonnaise (14g) has 94 calories. A teaspoon (5g) has 31 calories, and a quarter cup (58g) jumps to 394. Per 100g, regular mayo runs 680 calories, with its 75g of fat supplying nearly all of them.

Where does the 94-calorie figure for mayonnaise come from?

The 94 calories per tablespoon comes from USDA FoodData Central (FDC ID 171009) for regular soybean-oil mayonnaise, measured at 14g per tablespoon. Major brands like Hellmann's, Best Foods, and Kraft Real Mayo list 90-100 calories per tablespoon, all within USDA's reference range. Light mayo and olive-oil mayo run 35-50 cal per tablespoon.

Why does a tablespoon of mayonnaise weigh 14 grams?

USDA standardizes a level tablespoon of mayonnaise at 14g, about half an ounce. A heaping spoonful can easily reach 25g, which is 170 calories instead of 94. At 6.8 calories per gram, weighing mayo on a kitchen scale beats eyeballing a spoon every time.

How much mayonnaise per day is okay for weight loss?

One level tablespoon a day (94 calories) fits most weight loss budgets without trouble. Two tablespoons cost 188 calories, roughly 10% of an 1,800-calorie day, before you count the bread or the filling. Light mayo at 45-50 calories per tablespoon, or regular mayo cut 50/50 with Greek yogurt, halves the hit.
