Calorie Need The calculator below calculates your calorie intake needs based on your desired weight goals. BMI The body mass index (BMI) is a measure that uses your height and weight to work out if your weight is healthy.
- below 18.5 – you're in the underweight range
- between 18.5 and 24.9 – you're in the healthy weight range
- between 25 and 29.9 – you're in the overweight range
between 30 and 39.9 – you're in the obese range BMR The Basal Metabolic Rate, or BMR, is an estimate of how many calories you would burn if you were to do nothing but rest for 24 hours. It’s the amount of energy you need while resting in a temperature environment during the post-absorptive state, or when your digestive system is inactive. Age: BMR decreases as age increases. Gender: Males have a higher BMR than females. Increased intake of foods: Eating larges amounts of food requires more energy to process more material. Pregnancy: BMR increases during pregnancy and lactation.
