Significance of Percent UBW
– 1 –
Perform the following calculation to determine the percent weight change:
percent weight change = percent UBW-100
Decide. duration of weight gain or loss ie how long ago the weight has consistently been near the UBW yours. Ideally this duration will be between a week and six months

A week — moderate: less than 1 percent significantly: 1 to 2 percent severe: more than 2 percent;
One month — moderate: less than 5 percent significantly: 5 percent; severe: more than 5 percent
Three months — moderate: less than 7. 5 percent significantly: 7.5 percent; severe: more than 7.5 percent;
