BMR should be given and settable as it doesn't always fit by the one calculated by a nutrionnist

Hi everyone,

I have a big issue with health trackers. I bought a Fitbit to motivate myself to lose weight. I also decided to follow a nutritionist who calculated my BMR using medical equipment. She discovered that I wasn’t eating enough each day because I was trying not to overeat based on the calories burned according to my Fitbit. There was nearly a 500-calorie difference, which is significant. Apparently, beneath the fat, I’m quite muscular...

It’s quite paradoxical to have bought a tracker with the aim of getting healthier, only to find that it puts you at risk...

Hello @sishy and welcome to the Community.  All fitness trackers use one of several equations to estimate BMR calories.  Fitbit uses the Mifflin-St Jeor equation, the one that is considered to be the most accurate.  Other Fitness trackers aren't so straightforward.  But they are all estimates.  I did a brief search.  I couldn't find any brand of fitness tracker that lets you customize your BMR.

I moved your post to the Manage Weight forum, a better fit for this topic.

Hi LZeeW,

Thanks for your answer even if you dodge the purpose of my post by answering by something that was even not questioned ...
