Your Ideal Weight

The most accurate assessment of your ideal weight takes into account the composition of your body - how much of your weight is lean body mass (muscle and bone) and how much is body fat. For optimum health, body fat should be no more than 20% of total body weight for men and 30% for women.

Ideal Weight Table

The following table is a guide to a healthy weight range for each height and gender based on the Body Mass Index (BMI) normal accetable range[1]. The table does not take into consideration your age or your frame size. A person with a petite physique (small frame) should aim for an ideal weight at the lower end of the range and a person of the same height but with a large frame could quite satisfactorily weigh in at the top of the range.

Body Mass Index

An alternative way of gauging your weight is to calculate your Body Mass Index (BMI). To determine your BMI divide your weight in kilograms by your height in metres squared.

  • BMI = Weight in Kg ÷ Height in metres∧2

The normal acceptable range of this measurement is 20.1 to 25.0 for men and 18.7 to 23.8 for women.

The only exceptions are athletes and body builders, whose extra muscle may tip their BMI over the normal range.

Vikram et al. (2003)[2] in his study showed that Asian Indians have excess cardiovascular risk at BMI values considered “normal” and therefore the definitions of “normal” ranges of BMI need to be revised for Asian Indians.

An alternative equation for calculating BMI

In an article in The Times (2013)[4] Professor Trefehan says that the current calculation of BMI results in short people thinking they are thinner than they are and tall people thinking they are fatter. He feels that the correct equation for calculating and individuals BMI is:

  • BMI = 1.3 x (Weight in Kg ÷ Height in metres∧2.5)

Assessment of your BMI score

The following BMI assessment is provided by NHS Direct (2011)[1]

  • less than 18.5 you are underweight for your height.
  • 18.5 to 24.9 you are an ideal weight for your height
  • 25 to 29.9 you are over the ideal weight for your height
  • 30 to 39.9 you are obese
  • over 39.9 you are very obese

If your BMI is greater than 30 then you should consider taking action to lose weight.

Estimated Energy Requirements (EER)

The following calculator provides the Estimated Energy Requirements (calories/day) you require to maintain your current weight.

To obtain an estimate of your EER please enter your gender, age, activity level, height, weight and then select the 'Calculate' button.

Activity Level
Height metres Weight kg's
Your EER is calories/day

The official formulas for the calculation of your daily estimated energy requirements (EER) are provided by the Food and Nutrition Board of the Institute of Medicine of the National Academies. (Trumbo et al. 2002)[3]

  • EER Male = (662 - (9.53 x Age)) + (PA x ((15.91 x Weight) + (539.6 x Height)))
  • EER Female = (354 - (6.91 x Age)) + (PA x ((9.36 x Weight) + (726 x Height)))

PA indicates your Activity Level and is equal to 1.0 for Sedentary, 1.12 for Low Active, 1.27 for Active and 1.45 for Very Active. Weight is measured in kilograms and height in metres.

History of ideal weight formulas

A number of formulas and theories have been devised over the years and the following are some of those most popular "ideal weight" formulas:

  Men Women
Dr P. Broca (1897) Height (cm) -100 +- 10% Height (cm) -100 +- 15%
G. Hamwi (1964) 48kg + 2.7kg/inch over 5 feet 45.5kg + 2.2kg/inch over 5 feet
B. Devine (1974) 50kg + 2.3kg/inch over 5 feet 45.5kg + 2.3kg/inch over 5 feet
J. Robinson et al. (1983)[5] 52kg + 1.9kg/inch over 5 feet 49kg + 1.7kg/inch over 5 feet
D. Miller Formula (1983) 56.2kg + 1.41kg/inch over 5 feet 53.1kg + 1.36kg/inch over 5 feet
H. Lemmens et al. (2005)[6] 22 × Height2 (metres) 22 × Height2 (metres)

To obtain an estimate of your ideal weight, based on these formulas, please enter your height and then select the 'Calculate ' button.
