Hello GLORAGNYNY,
Have you heard of BMI (Bady Mass Index)?
Well BMI (Body mass index) is a measure of body fat based on height and weight that applies to both adult men and women.
These are the BMI Categories:
Underweight = less then 18.5
Normal Weight = 18.5 to 24.9
Overweight = 25 to 29.9
Obesity = 30 and above
You can go to your MySpark and click on "CHANGE DIET GOALS" where you'll see your BMI chart. From your BMI you'll know what your weight should be.
Good luck
