Nutrition Tips

Focus on whole, nutrient-dense foods like lean proteins, fruits, vegetables, whole grains, and healthy fats
Stay hydrated by drinking adequate water throughout the day

Important Notes

This calculator provides an estimate; your actual calorie needs may vary
For personalised advice, consult with a registered dietitian or healthcare provider
Never consume fewer than 1200 calories daily (for women) or 1500 calories daily (for men) without medical supervision
Re-calculate your calorie needs periodically as your weight and activity levels change

Understanding Calorie Needs

Your daily calorie needs depend on several factors including your age, gender, height, weight, body composition, and activity level.

Key Components

Basal Metabolic Rate (BMR): The calories your body needs for basic functions at rest
Total Daily Energy Expenditure (TDEE): BMR plus calories burned through daily activities and exercise
Macronutrients: Protein, carbohydrates, and fats that provide calories and nutrients

BMR Calculation Methods

Mifflin-St Jeor Equation: Considered the most accurate for most people
Harris-Benedict Equation: One of the earliest and widely used BMR formulas
Katch-McArdle Formula: Accounts for lean body mass and may be more accurate for athletic individuals

Macronutrient Balance

Protein: 4 calories per gram - important for muscle repair and growth
Carbohydrates: 4 calories per gram - primary energy source
Fat: 9 calories per gram - essential for hormone production and nutrient absorption

Weight Management

For weight management:

Maintain weight: Consume your TDEE
Lose weight: Create a calorie deficit (consume less than your TDEE)
Gain weight: Create a calorie surplus (consume more than your TDEE)

A safe and sustainable rate of weight change is generally 0.5-1 kg (1-2 pounds) per week.

Understanding the Calorie Calculator

Why Are Calories Important?

Calories are a measure of energy. Your body needs energy to function properly, and the number of calories you consume directly affects your weight. Here are some reasons why keeping track of calories is crucial:

Body Measurements Matter

Your height and weight are also crucial inputs for the calculator. Depending on whether you use the metric or imperial system, you’ll need to enter your measurements accurately. Understanding your body mass index (BMI) is important as it gives insight into your overall health and helps tailor your calorie needs.

Activity Level: What’s Your Routine?

How active you are in your daily life can significantly affect your calorie needs. The calculator allows you to select from different activity levels, ranging from sedentary to very active.
