It is fairly easy to calculate weight loss by using percentages. Simply divide the amount of weight the person lost by their original weight. For instance, if a person lost eight pounds and their original weight (before losing) was 160, then they had a 5% weight loss because eight divided by 160 is .05 or five per cent. It may be easier for you to use a calculator in order to determine percentages. It can be an effective way to evaluate weight loss because of varying weights. Someone who weighs less may have less to lose than someone who weighs more. Using percentages is the way that a lot of trainers look at weight loss. Many prefer to look at measurements, however. Since muscle is more dense than fat, it takes up less space but can weigh more than the same capacity of fat. Therefore, a lot of people prefer to look at how their clothes fit rather than the scales.
