Several studies have looked at different digital body fat scales and how they stack up compared to the types of devices that are used in clinical research.
Leslie Heinberg, PhD, Director of Enterprise Weight Management at Cleveland Clinic, says research has found that most of these scales are fairly inaccurate and tend to overestimate body fat percent. Plus the extra bells and whistles on these products can produce distressing results.
“One of the biggest concerns in using these scales is getting the wrong information and it causing unnecessary stress,” says Dr. Heinberg.
The readings might be so discouraging, that they could cause a person to give up or engage in extreme or unhealthy diets.
Getting feedback on weight and body fat percentage can be helpful, however, numbers aren’t always the best measure of healthy behavior.
Percent body fat is a great thing to keep track of before you initiate a diet or exercise program and checking on it from time to time can be beneficial. But checking it every day or every few days is not going to help your mental health.
If you really want an accurate assessment then make an appointment with your doctor. There are clinical ways that can measure more accurately than what you can do at home.
