Two people following identical diet and exercise plans are likely to lose weight at different rates, despite similar habits. Researchers at the National Institutes of Health (NIH) examined the mechanisms behind these differences, and developed a tool that may provide individuals with tailored weight-loss plans.
While the computer-simulated metabolic model is still a prototype meant for research, the scientists are working to refine and simplify it for widespread use.
The NIH officials said their mathematical model will help predict changes in metabolism over time, taking into account an individual’s gender, age, height, weight, body fat and resting metabolic rate.
“It’s a good reality check for how long weight loss takes, and what changes in eating and exercise are required to achieve and maintain goal weight,” said first author Kevin Hall, Ph.D.
The researchers expect that the tool will be able to tell individuals how long it will take them to reach their goal weight when they cut out a certain amount of calories per day through dietary means and burn fat with exercise.
