Strategies for Success in Weight Management

By: James J. Messina, Ph.D.


Calculating lean body mass

The best weight for you is your lean body mass (everything but fat) plus just the amount of fat necessary for good health:

10 percent to 18 percent of total body weight for men

18 percent to 25 percent of total body weight for women

A health professional can estimate percentage by measuring body fat with skinfold caliper

Calculating Lean Body Mass


Body mass index

Most people do not have their lean body mass measured

A more common, but less accurate, way to determine your ideal weight is to use standard weight charts based on a person's height and frame

BMI: Measures weight (in kilograms) divided by height, squared

Body Mass Index


Body mass index ranges

Body Mass Index Ranges


Ideal calculated weight

For Men: 106 lbs. plus six lbs. for each inch in height over five feet

For Women: 100 lbs. plus five lbs. for each inch in height over five feet

Using NIH guidelines, roughly 100 pounds greater than the ideal Calculated Weight constitutes clinically severe obesity

Ideal Calculated Weight


How the charts got started

How the charts got started

  • 1942, Louis Dublin, a statistician at Metropolitan Life Insurance Company, grouped four million of MetLife insured Put categories based on height, body frame (small, medium or large) & weight

  • Discovered who lived longest were ones who maintained their body weight at the level for average 25-year-olds


How the charts got started1

How the charts got started

  • Metropolitan Life tables widely used for determining recommended body weights

  • 1942 tables gave "ideal body weights“

  • 1959 revised as"desirable body weights“

  • 1983 revised as "height and weight tables"

  • Weights given in the 1983 tables are heavier than the 1942 tables because, in general, heavier people live longer today


Critique of metlife charts

Critique of MetLife Charts

  • Insured people tend to be healthier than uninsured people

  • Frame size was never consistently measured

  • People included were predominantly white & middle-classed

  • Some persons were actually weighed, some were not

  • Some wore shoes and/or clothing, some did not

  • Tables do not consider percentage of body fat or distribution known as factors in longevity


Use of the charts

Use of the Charts

  • Many experts say 1942 tables are more accurate because they indicate lower "ideal weights"

  • Many experts support the use of the 1983 tables, citing that these are the latest statistical sampling of such matters

  • The American Heart Association recommends using 1959 tables rather than the newer tables that suggest somewhat higher weights


Charts make it obvious

Charts make it obvious

  • US Army, US National Center for Health Statistics, North American Association for Study of Obesity & USDA

  • There is no consensus of "ideal body weight"

  • It is different for every individual

  • Depends on health, body fat content & distribution, musculature, age, activity, metabolism, & other factors not simple to measure accurately


What we learn from looking at charts

What we learn from looking at charts

  • You & your physician or dietitian must decide what your ideal weight should be

  • You probably have an idea what that weight is

  • Start conservatively

  • If you reach your target weight & still feel you need to trim off additional weight, you always have option to set a new target goal.
