CalBye – AI Calorie Tracker

Mayonnaise calories add up quickly because mayo is dense in fat even though the portion size often looks small. A practical estimate is about 31 calories for one teaspoon and around 94 calories for one tablespoon. That is why sandwiches, dressings, salads, and dipping sauces can become much heavier than expected when mayo is used generously.

Part 1. Mayonnaise Calories by Spoon Size

One teaspoon of mayonnaise is often about 31 calories, while one tablespoon is around 94 calories. Two tablespoons can move close to 190 calories, which is why mayo-heavy sandwiches and salads often rise faster than users expect.

Part 2. Nutrition Facts for Mayonnaise

One tablespoon of mayonnaise provides about 10 g fat, almost no protein, very little carbohydrate, and a moderate amount of sodium depending on the brand. From a nutrition perspective, mayo is mainly a fat-based condiment rather than a meaningful protein or fiber source.

Part 3. Why Mayo Adds Up So Quickly

The biggest reason is that mayo is calorie-dense for a very small volume. Users often think in terms of a sandwich or salad as one item, but the mayo inside can quietly add a large amount of calories without making the portion look much bigger.

Part 4. How to Track Mayonnaise with CalBye

• Log teaspoon or tablespoon amounts instead of guessing from the sandwich alone.
• Count aioli, flavored mayo, and mayo-based dressings separately when possible.
• Use a higher estimate for deli salads and restaurant sauces where mayo is often heavy.
• Use CalBye to make condiment tracking more visible and consistent.
