What is Free Calorie Calculator 🔥?

The HIF Logic Free Calorie Calculator combines two tools in one: a food calorie lookup database and a daily calorie needs calculator. Food Calorie Lookup searches a database of 100 common foods and returns calories, protein, carbohydrates, fat, and fiber per serving. You can adjust the number of servings and all values scale live. The Daily Needs Calculator uses the Mifflin-St Jeor equation — the most widely validated BMR formula in clinical nutrition research — to compute your Basal Metabolic Rate (BMR) and Total Daily Energy Expenditure (TDEE). Mifflin-St Jeor Equation: Male: BMR = (10 × weight in kg) + (6.25 × height in cm) − (5 × age) + 5 Female: BMR = (10 × weight in kg) + (6.25 × height in cm) − (5 × age) − 161 Where: weight in kg = lbs ÷ 2.205 height in cm = (feet × 30.48) + (inches × 2.54) TDEE = BMR × Activity Multiplier Activity multipliers: Sedentary (little/no exercise) × 1.200 Lightly active (1–3 days/week) × 1.375 Moderately active (3–5 days/week) × 1.550 Very active (6–7 days/week) × 1.725 Extra active (physical job + exercise) × 1.900 Example — 30-year-old male, 170 lbs (77.1 kg), 5'10" (177.8 cm), moderately active: BMR = (10 × 77.1) + (6.25 × 177.8) − (5 × 30) + 5 = 771 + 1111 − 150 + 5 = 1,737 cal/day TDEE = 1,737 × 1.55 = 2,692 cal/day The Mifflin-St Jeor formula was developed in 1990 and validated against indirect calorimetry. It is preferred over the older Harris-Benedict equation for general population use.

How to Use This Tool

1
Choose a mode: "Food Calorie Lookup" to check the calories in a specific food, or "Daily Needs (BMR / TDEE)" to find out how many calories your body needs per day.
2
Food Lookup: start typing a food name (e.g. "chicken", "banana", "oatmeal"). A dropdown of matches appears — click one to select it.
3
Adjust the serving count. All calorie and macro values scale automatically. The macro bar shows the protein/carb/fat breakdown visually.
4
Daily Needs: select your biological sex, then enter age, weight (lbs), height (feet + inches), and activity level.
5
Click "Calculate My Daily Calories" to see your BMR and TDEE, plus a goal-based calorie target table showing ranges for weight loss, maintenance, and muscle gain.

Real-World Use Cases

Planning a High-Protein Breakfast

Look up "Greek Yogurt" (150 cal, 17g protein per cup) and "Egg whole" (72 cal, 6g protein each). If you eat 1 cup of yogurt and 2 eggs, that's 294 calories and 29g of protein — a solid high-protein start to the day. Adjust servings to hit your exact target. The macro bar instantly shows you the protein-dominant breakdown.

Finding Your Cutting Calories

Enter your stats into the Daily Needs calculator — say you're a 28-year-old female, 145 lbs, 5'5", moderately active. Your TDEE comes out to roughly 2,100 calories. The goal table immediately shows you that a moderate deficit (−500 cal/day) puts you at 1,600 calories — a sustainable rate of about 1 lb per week of weight loss without extreme restriction.

Comparing Snacks by Calories and Macros

Trying to decide between a handful of almonds vs. potato chips? Search "almonds" (164 cal, 6g protein, 14g fat per oz) and then "potato chips" (152 cal, 2g protein, 10g fat per oz). Nearly identical calories, but almonds have 3x the protein and 4g of fiber. That macro breakdown changes the picture even when calorie counts are close.
