Where does the weight come from?

Although I would agree with the percentages on that chart, the formula is worthless.

BMI is a just a formula based on height and weight.  It does not take into account body fat% or bone structure. 

Using another formula, based on a generic formula to calculate body fat doesn't make any sense.

No idea who your scale works, the Aria looks at your weight, and then sends a electrical charge through your body and gets a biometric reading.  It takes that reading, and uses a table of know people that weight the same as you do, that had the same biometric reading, and assigns a fat percentage based on that table.

Is the Aria correct no?  But it's close.  Using that formula, my body fat should be 31%.  Aria says 28% to 29%. 

I know on my Aria, you have to setup users.  If you don't all it shows is the weight.  That might be the same with your scale.

Only way to know for sure is go to a gym and have them use their equipment to measure your body fat %.

If I were you, I'd watch both my weight, and that body fat %.  If you see the weight drop, but the % does not change much, or worse goes up, then you know you lost mostly muscle.  If you see the fat percentage go down more than the weight you lose, then you are gaining muscle, and losing fat.

Ideally they should both come down at the same time...

same with my scale, you can setup users, but still the same, it only gives the weight for them, it is like they are wearing sllippers or the skin on their feet is too thick lol

In my opinion, it's easy for the average person to overthink the weight loss formula. The simple formula is most people will lose close to a pound for every 3,500 calorie deficit. The Fitbit Surge seems to count calories accurately if the heart rate monitor is on. The Fitbit Zip underestimates calories by about 20% (multiply by 1.25 to get actual reading.) I recommend picking a calorie deficit and sticking to it for a couple weeks to see if it works. I don't advise going below the number of calories for an individual's basic metabolism rate. Increase excercise if needed to get the deficit.

Calorie counting is the only thing that works for me. It makes weight loss scientific instead of artistic. People succeed both ways. The best system for me is to decide what I want to eat at the beginning of the day and make changes if I add something. 

I think worrying too much about losing muscle instead of fat is not needed. People will retain the muscles they need. It's natural to lose some muscle as weight is loss as the muscles aren't needed to carry the weight. 

Starvation diets can cause serious physical problems. What constitutes a starvation diet depends on the activity level. I find it easy to maintain large calorie deficits with lots of exercise. 

A person's diet does make a difference. Unfortunately, the popular opinion is to eat more fat and protein. Both cause physical problems and a shorter life. I recommend reading "The Starch Solution" by Dr. McDougall for what I consider to be the right answer for most people. Elite athletes may need a different diet, but few of us are there yet.

I originally wanted to get a fitbit that also monitors the heart rate etc, but I don't trust wrist ones, with the arms moving throughout the whole day, the steps, calories will be wrong

Especially when on the exercise bike, only part of the body moving is the legs
