Interesting Calorie Facts
What is a Calorie?
A calorie is the amount of energy needed to raise the temperature of 1 gram of water by 1°C. Food calories are actually kilocalories (1000 calories).
Brain Power Consumer
Your brain uses about 20% of your daily calorie intake, roughly 400-500 calories, despite being only 2% of your body weight.
Burn While You Sleep
You burn 40-80 calories per hour while sleeping. An 8-hour sleep session burns 320-640 calories through basic metabolic functions.
Fidgeting Burns Calories
Restless movements like tapping feet or fidgeting can burn up to 350 extra calories per day through non-exercise activity thermogenesis (NEAT).
Negative Calories Myth
No food has 'negative calories.' While celery has few calories (6 per stalk), you don't burn more digesting it than it provides.
Olympic Swimmers
Michael Phelps reportedly consumed 12,000 calories daily during training - that's 5-6 times the average person's intake!
Walking vs Running
Running burns about 2x more calories per minute than walking, but walking the same distance burns roughly the same total calories.
MET Explained
MET (Metabolic Equivalent of Task) measures exercise intensity. 1 MET = resting, 3-6 MET = moderate activity, 6+ MET = vigorous activity.
