NIH Body Weight Planner Helps Users Set Weight Goals

Form on screen shows several spaces for entering data

For those who would like to lose weight, but don’t know where to start, the NIH Body Weight Planner might be a good place to begin. 

Developed by NIDDK’s Dr. Kevin Hall, the Body Weight Planner forecasts how body weight changes after people alter their diet and exercise habits. It takes into account what happens when people of varying weights and diet and exercise habits try to reduce their weight. 

The planner asks for a person’s height, weight and age. It also asks for his or her current physical activity level, what the goal weight is and the time frame for reaching the goal. Then, the planner calculates how many calories a person must eat to maintain current weight and reach and maintain the goal weight.
