There are many ways to track this. Here are some of them...
Healthy Body Calculator
This uses many of the ones below and combines them
BMI (Body Madd Index)
To find this you will need to multiply your weight by 703, then divide it twice by your height in inches. (There are 60 inches in 5 feet)
Ex... You weight 175 lbs. And are 5'5" (65 inches) tall, your formula would look like this...
175 X 703=123,025 Divide that by 65= 1.892.69 And then divide again by 65=29.1
The numbers mean:
Below 18.5 underweight, 18.5-24.9 Normal, 25.0-29.9 Overweight, 30.0 and Above Obese
You can also do this online. But thought you might like to see the math formula yourself!

Body Shape Standards
Measure your waist at your belly button and hips at the widest part. Divide your waist by your hip to get waist-hip ratio. Ideally this number should be 0.80 or less.
Figure Your Frame Size
Measure your waist, hips, and thighs. I also measure your arms, calves, bust, underbra and neck. It is best to find a freckle or other blemish to measure at every time. Especially on your arms and thighs. Then write it down with the date. You can then see how many inches you have lost since you started and from the time you last measured. It is fun to see the results of your work.
