About Calorie Calculator
- A calorie calculator is a tool used to estimate the number of calories an individual needs to maintain, gain, or lose weight. It takes into account factors such as age, gender, weight, height, activity level, and weight goal. The Harris-Benedict equation and the Mifflin-St Jeor equation are commonly used formulas to calculate basal metabolic rate (BMR). BMR represents the number of calories required for basic bodily functions at rest. Activity level is factored in using an activity multiplier to determine total daily energy expenditure (TDEE). To lose weight, one can create a calorie deficit by consuming fewer calories than their TDEE. To gain weight, a calorie surplus is needed. However, it's important to consult a healthcare professional or registered dietitian before making significant changes to one's diet based on the calculator's results.
