Just last week, military brass vowed that the force of the future would be smaller and leaner. Apparently, the Armys taking that pretty damn literally. They want smaller, leaner soldiers. Their best idea to do it? Give GIs transplants of extra fat cells.
Seriously. In the Armys latest round of small-business research awards, theyve green-lit a proposal to manufacture transplantable brown fat cells, all in an effort to catalyze rapid weight loss. Portlier soldiers, you might recall, are turning into a major dilemma for top brass. An estimated 75 percent of todays young Americans are either too fat, too sickly or too dumb to serve. The Armys even overhauled their fitness program, in part to accommodate softer recruits, by swapping long runs and grueling drills for yoga and calisthenics.
Leg lifts and downward dogs, however, dont offer much of a calorie-burning boost. Brown fat tissue, however, does. At first glance, the idea of adding fat to get rid of fat doesnt exactly add up. After all, thousands of Americans dole out mad cash to have flab sucked out, not put back in.
The distinction comes down to varieties of fat: Humans carry pockets of conventional fat, or white adipose tissue. They also carry brown adipose tissue. And recent research has confirmed that the stuffs pretty damn special: It burns a ton of calories around 250 calories over three hours in one study group and actually sucks energy out of conventional fat cells to fuel its fire. Research even suggests that additional pockets of brown fat can be created by exercise.
The Army, however, would rather see soldiers drop pounds like the Real Housewives with as little effort as possible. Theyre funding a team at Boston University to generate human [brown adipose tissue] for subsequent human transplantation. Obesity and its associated metabolic complications are becoming increasingly prevalent in military personnel, the Armys research award notes. Increasing [brown fat] by about 50 grams in obese patients could induce strong weight loss and improve metabolic status.
Researchers plan to isolate a brown adipose progenitor cell cells that, similarly to stem cells, are able to differentiate into more specific types and then generate additional brown adipose cells in the lab. From there, theyd be able to offer transplantation therapy to portly personnel.
