Interactive Weight Management Tool

Weight Loss based on Calorie reduction from food and increased daily activity

Move green dot to desired pounds / week weight loss from food reduction

Move red dot to additional Daily Energy Expenditure (DEE) calories

Reduced food calories Additional exercise calories Total reduction: food and exercise calories Weight loss: Pounds per week

[2] The United States Center for Disease Control (CDC) has an ongoing series of studies called the National Health and Nutrition Examination Survey, or NHANES. The NHANES_III data set contains records for 33,994 individuals, although not all participants took part in every section of the survey. Eliminating all records that do not have BIA data reduces the data pool to 17,660 records of men and women that were used to create the average and variance (standard deviation) of the ranges in this chart, except for body fat where the standards of the American College of Sports Medicine are used for a more ideal fat distribution.
