Step 1
First, write down your starting weight so that you don't forget over the next few weeks. Then when you weigh yourself again the next week, calculate your total weight change (hopefully, a Loss!) by subtracting your recent weight from your starting weight.
-
Step 2
Now that you know your pounds lost for the week, divide it by your starting weight. This will give you a fraction such as .325.
-
Step 3
Multiply your answer in step 2 by 100 and round to the nearest tenth. Now you know the percentage of your weight loss and compare it with those on the Biggest Loser. Happy dieting!
