NIH research model predicts weight with varying diet, exercise changes – 3
Narrator: This is NIH Health Matters. I’m Joe Balintfy. Recent findings are challenging the commonly held belief that eating 3,500 fewer calories or burning them off exercising will always result in a pound of weight loss.
Hall: So what that rule, which has been you know ubiquitous, fails to consider is the fact that as I lose weight my metabolism slows down. And so the rate of weight loss is drastically over estimated.Narrator: NIH researcher Dr. Kevin Hall says a new mathematical model helps improve predictions and provides new methods for assessing what a realistic weight loss would be for a given diet change. A simulation based on the model is online at http://bwsimulator.niddk.nih.gov. Health Matters is produced by the National Institutes of Health, part of the U.S. Department of Health and Human Services.
