Navy: Forged by the cheese A new study reveals that the one service is by far the heaviest, when it comes to obesity rates. Got a guess on which one?

Sailors need remedial physical training.

That could be one just one of many conclusions drawn by a recent Department of Defense study that found the Navy earned the dubious honor of surpassing all other branches in its rate of obese personnel.

The overall rate of fat service members is also up from recent years, with the percentage of personnel weighing in at obese standards climbing to over 17 percent, according to a Health of the DoD Force study.

That number spiked to over a quarter of service members over the age of 35.

For the Navy, the overall number of obese personnel was a shocking 22 percent. The other branches reported the following frequency of obesity:

Air Force: 18 percent

Army: 17 percent

Marine Corps: 8.3 percent

And while the Marine Corps was the least overweight of the bunch — a characteristic partially attributable to the Corps having the youngest average age of personnel — the Marines reported the highest rate of knee and back injuries.

The Navy, meanwhile, reported the lowest incidence rate of cumulative injuries. How much of that could be related to inactivity was not determined.

A staggering number of troops are fat and tired, report says Glaring concerns over weight and sleep issues for military personnel were raised in a 2018 RAND report.

Rates of obesity were configured using the oft-criticized body mass index measure, which indicates a service member is obese if their BMI reads 30 or higher.

“This report highlights obesity as a growing health concern among Sailors,” the study’s authors commented about their findings, which were first reported by Stars and Stripes.

“Obesity contributes to hypertension, diabetes, coronary heart disease, stroke, cancer, all-cause mortality, and increased healthcare costs.”

It also costs the DoD significant coin.

“The Department of Defense, our nation’s largest employer, spends about $1.5 billion annually in obesity-related health care costs for current and former service members and their families, as well as costs to replace unfit personnel,” a recent study by the Centers for Disease Control and Prevention claimed.

Overweight and obese active duty military also cost DoD $103 million per year in the form of 658,000 lost workdays, the study found.

“In the civilian world, unfit or overweight employees can impact the bottom line,” retired Air Force Gen. Richard E. Hawley said in the CDC study. "But in our line of work, lives are on the line and our national security is at stake.

The civilian world is one in which, as of 2015, one in three young adults are considered too fat to enlist, contributing to a difficult-to-navigate environment for recruiters in finding suitable candidates for military service.

A 2018 RAND Report that analyzed rates of both obese and overweight troops painted a grim picture of the military’s physical fitness standards.

The study, featuring roughly 18,000 randomly selected participants across each of the service branches, reported that almost 66 percent of service members are considered to be either overweight or obese, based on the same BMI measurement standard used in the DoD study.

Broken down by service, the 2018 report lists the Army as the branch accounting for the highest percentage of overweight troops, with 69.4 percent of soldiers falling under this category.

The Army was followed by the Coast Guard (67.8 percent), Navy (64.6 percent), Air Force (63.1 percent) and Marine Corps (60.9 percent).

“If we don’t take steps now to build a strong, healthy foundation for our young people, then it will not just be our military that pays the price," retired Rear Adm. Richard R. Jeffries said in the CDC study.

“Our nation as a whole will suffer also.”
