Example Calculations
Example 1: Weight Loss
Starting Weight = 200 lbs
Current Weight = 180 lbs
Weight Change:
180 − 200 = -20 lbs
Percentage Change:
(-20 ÷ 200) × 100 = -10%

- Percentage decrease: 10%
Example 2: Weight Gain
Starting Weight = 140 lbs
Current Weight = 150 lbs
Weight Change:
150 − 140 = 10 lbs
Percentage Change:
(10 ÷ 140) × 100 = 7.14%
Result:
- Weight gained: 10 pounds
- Percentage increase: 7.14%
Example 3: No Weight Change
Starting Weight = 170 lbs
Current Weight = 170 lbs
Weight Change:
170 − 170 = 0
Result:
- No change in body weight
