Nutrition facts per 100g (fresh lemon)
Lemon nutrition: wedges, juice, water, dressings, and portions
Fresh lemon has about 29 calories per 100g. A wedge or squeeze of lemon juice usually adds very few calories, which is why lemon is useful for flavoring water, salads, fish, and chicken.
The calories usually come from what lemon is mixed with: oil-based dressings, sugar, honey, butter, or sauces. Scan the full plate with the CalMind photo calorie tracker to separate lemon from higher-calorie ingredients.
CalMind estimates calories, macros, and portion size from your meal photo, then helps you keep sauces, toppings, and sides separate.
Lemon juice vs whole lemon
Lemon juice is very low in calories per tablespoon, while whole lemon includes peel and fiber. Most tracking errors happen when lemon is part of lemonade, vinaigrette, or creamy sauce.
Low-calorie flavoring
Lemon is a good substitute for heavy sauces because it adds acidity and brightness with minimal calories. For weight loss, pair lemon with herbs, vinegar, and measured oil instead of free-pouring dressing.
