The WHO definition is:

• a BMI greater than or equal to 25 is overweight
• a BMI greater than or equal to 30 is obesity.

In May 2008, Diabetes Australia, the national body for diabetes awareness and prevention, told the House of Representatives that the cost of obesity on the country's health system in 2005 was an estimated A$25 billion.

BMI stands for Body Mass index. It is used to give you an idea of whether you’re underweight, overweight or an ideal weight for your height. It’s useful to know because if your weight increases or decreases outside of the ideal range, your health risks may increase.BMI does not differentiate between body fat and muscle mass. 

Body Mass Index (BMI)

        

Classification	BMI
Underweight	<18.50
Healthy Weight Range	18.6-24.99
Overweight:	25-29.99
Obese	30+

A much better way of determining ideal body weight is to ignore body weight all together and focus on level of total body fat.

Classification	Women	Men
Essential fat	10-13%	2-5%
Athletes	14–20%	6–13%
Fitness	21-24%	14-17%
Average	25–31%	18–24%
Obese	32%+	25%+

Easy and cheap way to determine body fat is using use electronic skinfold calipers:

Ideal weight and ideal food intake:
Basal metabolic rate (BMR), and the closely related resting metabolic rate (RMR), is the amount of energy expended daily by humans and other animals at rest.  Total Daily Energy Expenditure (TDEE) - This it the BMR times an energy multiplier that is designed to account for how active you are.

Use the formula to calculate BMR, TDEE:
