Protein and Intentional Weight Loss

When weight is lost through caloric restriction, a higher protein intake is usually seen as a good idea due to preserving lean mass during the weight loss period.

A study that stratified gender found that a 500kcal dietary restriction for one year resulted in 9.9-11.2% weight loss in overweight persons with no difference between gender and overall weight lost did not differ between the high protein group (1.6g/kg) and the low protein group (0.8g/kg); when measuring only fat mass, the high protein group lost significantly more fat (14.3±11.8%) than did the low protein group (9.3±11.1%) when calories were kept equal. This study found that higher protein benefited both men and women, although men inherently lost more weight as a percentage of body fat.
