How do the weight gain/loss calculation and arrows work?
The FatSecret weight loss/gain calculation looks at a member’s weight change since their last weigh in and calculates a corresponding average weekly weight change. This weekly weight loss/gain is also displayed by an up or down arrow in a member’s journal entry if the weigh in and journal entry are done at the same time. So for example if a member has a one lb weight loss over a three day period since their last weigh in, this equals an average weekly weight loss of 2.3 lb.
