How to use
- 1 Search or browse for the food item by name.
- 2 Pick the serving size that matches what you're eating — often listed in cups, ounces, or grams.
- 3 The calculator returns calories per serving plus carb/protein/fat breakdown.
- 4 For mixed meals, add multiple items together. Track over a day to compare against your TDEE target.
- 5 Restaurant menu calorie counts can vary ±20% from actual — use this lookup as a sanity check, but home cooking with measured ingredients gives the most accurate count.

FAQ
Q How many calories are in a banana?
A medium banana (118 g, about 7 inches) has 105 calories per USDA FoodData Central, with 27 g of carbs, 1.3 g protein, 3.1 g fiber, and 0.4 g fat. A large banana (136 g) is about 121 calories. Cavendish bananas (the standard supermarket variety) are slightly higher in calories than other species.
Q How accurate are restaurant menu calorie counts?
FDA requires chains with 20+ locations to post calorie counts that are "reasonable estimates," but they're commonly off by ±20%. Combined with portion drift in real restaurants, you may be eating 30–40% more calories than the menu states. Take the higher estimate when tracking.
Q How many calories in a Chipotle burrito bowl?
Depends on selections. A typical chicken burrito bowl with rice, beans, salsa, and cheese is 600–900 calories. Add guacamole (+230), sour cream (+110), or queso (+120). Chipotle's online nutrition calculator gives precise totals for your exact build.
Q Are calories on packaged food labels accurate?
FDA allows ±20% variance on Nutrition Facts panel calories. Most major brands fall within ±10% in independent testing, but small or international brands sometimes vary more. For weight loss precision, weigh dry ingredients in grams rather than relying on serving counts.
Q How many calories should I eat per day?
Depends on age, sex, weight, height, and activity level. The USDA Dietary Guidelines provide rough ranges: most adult women need 1,600–2,400 kcal/day; most adult men need 2,000–3,000 kcal/day. Use a TDEE calculator with your specific stats for a personalized target.
Q How many calories in an avocado?
A whole medium Hass avocado (~200 g) has about 320 calories per USDA: 17 g carbs (most as fiber), 4 g protein, 29 g fat (mostly monounsaturated). A standard "serving" of one-third avocado (50 g) is 80 calories — useful for tracking when slicing.
Q Why do whole foods have lower calorie density than processed foods?
Whole foods (vegetables, fruits, lean proteins) have high water content and fiber that bulk up volume without adding calories. Processed foods concentrate calories by removing water and fiber and adding fats and sugars. A pound of broccoli is ~150 kcal; a pound of chocolate is ~2,500 kcal.
Q Is calorie counting the best way to lose weight?
It's effective but not the only path. Studies in JAMA and BMJ show that calorie restriction works regardless of diet composition, but adherence varies. Many people lose weight successfully without tracking by reducing portion sizes, eliminating sugary drinks, increasing protein and fiber, and walking more. Pick the strategy you can maintain long-term.
