Total weight is not, in and of itself, the best marker of fitness. For example, if youve added muscle mass (say, because youve been going to the gym and working out to lose weight) then your actual weight will have changed less than you might have wanted it to, but youre still in better shape.

In terms of actually understanding your overall health, the best thing you can probably do is talk to a doctor or other professional. Theyll let you know what signs to look for and how to keep track of your overall fitness and diet.
