1What’s Wrong With Weight Charts Going for the 3 Increases: Increase in Health, Increase in Happiness & Increase in EnergyStrategies for Success in Weight ManagementBy: James J. Messina, Ph.D.
2Calculating 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 men18 percent to 25 percent of total body weight for womenA health professional can estimate percentage by measuring body fat with skinfold caliper
3Body 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 frameBMI: Measures weight (in kilograms) divided by height, squared
4Body Mass Index Ranges 18 or less underweight (increased health risk) 19 to 24ideal weight25 to 29overweight (increased health risk)30 or higherexcessively overweight (significant health risk)
5Ideal Calculated Weight For Men: 106 lbs. plus six lbs. for each inch in height over five feetFor Women: 100 lbs. plus five lbs. for each inch in height over five feetUsing NIH guidelines, roughly 100 pounds greater than the ideal Calculated Weight constitutes clinically severe obesity
6How 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) & weightDiscovered who lived longest were ones who maintained their body weight at the level for average 25-year-olds
7How the charts got started Metropolitan Life tables widely used for determining recommended body weights1942 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
8Critique of MetLife Charts Insured people tend to be healthier than uninsured peopleFrame size was never consistently measuredPeople included were predominantly white & middle-classedSome persons were actually weighed, some were notSome wore shoes and/or clothing, some did notTables do not consider percentage of body fat or distribution known as factors in longevity
9Use of the ChartsMany 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 mattersThe American Heart Association recommends using 1959 tables rather than the newer tables that suggest somewhat higher weights
10Charts make it obviousUS Army, US National Center for Health Statistics, North American Association for Study of Obesity & USDAThere is no consensus of "ideal body weight"It is different for every individualDepends on health, body fat content & distribution, musculature, age, activity, metabolism, & other factors not simple to measure accurately
11What we learn from looking at charts You & your physician or dietitian must decide what your ideal weight should beYou probably have an idea what that weight isStart conservativelyIf you reach your target weight & still feel you need to trim off additional weight, you always have option to set a new target goal.
