I htink your height might be wrong...
it's currently listed as 137.2 - which translates to about 54 inches which is about 4'6" tall...
If you aren't 4'6" that would be why your bmi is calculating incorrectly
the weights listed for the past few weeks
184.0 137.2 183.0 181.5 179.0 177.5
would calculate correctly - Id' confirm your starting weight - -I don't think it was 184...
