It is every Marine’s responsibility to maintain the Marine Corps' body composition standards, or if not in adherence with standards, to take appropriate action to return to them in a timely manner. Marines on light or limited duty, whose medical condition precludes them from participating in specific activities, will be expected to participate in conditioning alternatives and dietary adjustments, in order to maintain these standards.
The Marine Corps' weight and body fat standards are health and performance based, and not based on appearance. Marines are considered not within these standards when their body weight and body fat exceed the maximum limits. Each Marine is weighed, at least semi-annually (annually for Reserves). The Marine is weighed, and the weight compared to the below chart. Only if the Marine exceeds the allowable weight on the chart, they are measured for body-fat. If they exceed the body-fat allowance, then the Marine is enrolled in the Body Composition Program - formerlly known as the "Weight Control Program." If the Marine is over the weight on the chart, but meets the body-fat standard, they are considered to be within the required standards, and no further action is taken.
The Marine Corps changed their body-fat standards, effective August 11, 2008: The new standards are:
MALE
AGE 17-26: 18%
AGE 27-39: 19%
AGE 40-45: 20%
AGE 46+ :21%
FEMALE
AGE 17-26: 26%
AGE 27-39: 27%
AGE 40-45: 28%
AGE 46+: 29%
If the Marine fails to lose the required weight/body fat while enrolled in the Body Composition Program, they can ultimately be discharged from the United States Marine Corps.
Note: No action is required for Marines who are below the Minimum Standards. Commanders may refer such Marines for a medical evaluation to determine if they are in good health.
