Just go by your TDEE ditch the gimmicky bullshit

They can be fairly inaccurate, specifically when it comes to lifting.
Like the other anon said, stick to your tdee and count your calories. The fit bit is still useful for holding yourself accountable to being more active, but don't think you can eat more because it tells you you're burning thousands of cals

Most calorie counter things overestimate on purpose. It's marketing. They want you to think, "oh, wow, this is great, look how many calories in burning using this product! Hey, all my friends, you should use this product as well!"
