Notes

We all have different ways of tracking and monitoring data.
Maybe you prefer to keep things as simple or straightforward as possible and avoid any/all numbers that don't have dollar signs in front of them. No judgment.
When it comes to monitoring your weight, you might take a less-is-more approach to numbers and metrics, so you want to keep your scale simple. You prefer the bare minimum when it comes to the numbers.
Conversely, it could be the case that you respond well to charts and graphs.
Smart scales give your weight, fat, and muscle mass, and other metrics that are uploaded to your phone, and this more complete picture of your health can be useful, according to John La Puma, M.D., a physician specializing in diet and health and the author of Refuel.

In a small study in Obesity Science & Practice, it was reported that people who used a smart scale were more likely to weigh in weekly than those who used a regular one.
That said, it's up to you to decide whichever method and scale is right for you and your body.
No matter your preference, remember that a scale is only a tool. Exercise and portion control are the keys. And according to dietician Dr. Lisa Young, weigh-ins should be kept to twice a week.
