CALORIES

The energy value of food is measured in units called calories. The average physically active man needs about 2,500 calories a day to maintain a healthy weight, and the average physically active woman needs about 2,000 calories a day. Calorie imbalance: calories consumed and calories spent leads to weight gain.

A BMI of 30 and above is considered obese. How do we calculate BMI. Body Mass Index is a simple calculation using a person's height and weight. The formula is BMI = kg/m2 where kg is a person's weight in kilograms and m2 is their height in metres squared. If your BMI is 18.5 to <25, it falls within the normal. If your BMI is 25.0 to < 30, it falls within the overweight range. If your BMI is 30.0 or higher, it falls within the obese range.
