I came across some articles on obesity and the military (see below). Metabolic syndrome, obesity being one part of it, is on the rise in the military and in the population in general, along with much else such as autoimmune and mood disorders.
Weight issues are not an issue of mere exercise, as I discovered in aging. The weight began accruing in my thirties and continued into my forties. I’ve always been active and so, in response, I became even more active. I had long done aerobic exercise multiple times a week, often long jogs and sometimes carrying extra weight. Weightlifting was added to my regimen these past few years. Still, the body fat wouldn’t budge. Besides, the worst rates of obesity are found among the young and so aging is not the issue, as further demonstrated by age-related diseases (e.g., what was once called adult onset diabetes) hitting hard at younger and younger ages.
Why is that? Some of it is basic biological changes in aging, of course — still, that couldn’t explain it all since it is happening in all age groups. I had improved my diet over time, but admittedly I was still eating a fair amount of carbs and sugar, even if no where near the amount the average American gets. In the wider population, the consumption of carbohydrates and added sugars has drastically increased over time, specifically as dietary percentage of red meat and saturated fat has gone down while dietary percentage of vegetables and vegetable oils has been on the rise. There are other complex factors that could be mentioned, but I’ll keep it simple.
The point is that the American population, in and outside of the military, are in compliance with official dietary recommendations. The military is even able to enforce a high-carb, low-fat diet on military personnel since they have few other choices when food is prepared for them, and it is specifically during deployment that military personnel have the worst diet-related health decline. There is no greater opportunity than the military for gathering highly-controlled dietary data, as the only other segment with more controlled diets are those locked away in institutions. Also, the military enforces a rigid exercise program, and those who join are those who self-selected for this lifestyle and then had to meet high standards to be accepted. Yet military personnel apparently are getting fatter and fatter.
The amount of carbohydrates we’re talking about here is not insignificant. The USDA recommends 50-60% of the diet to consist of carbohydrates with an emphasis on grains, most of those simple starchy carbs. Even adding some fiber back into processed foods doesn’t really make them any healthier. Grains alone brings up a whole mess of other issues besides gluten (e.g., grains block absorption of certain key nutrients) — it’s long been known that the best way of fattening animals is with grains.
To put in context how distorted is our diet, a recent study compared a high-carb and a low-carb diet where the latter consisted of 40% carbs. If that is what goes for low-carb these days, no wonder we are such a sickly population. Most traditional societies rarely get such high levels of carbs and what they do get usually comes from sources that are fibrous and nutrient-dense. Look at hunter-gatherers — 40% carbs would be at the extreme high end with many groups only getting 22% carbs. As a concrete example, compared to potato chips or a baked potato, chewing on a fibrous wild tuber is a laborious process because of how tough it is, only gaining slightly more calories than you’d be expending for all the effort.
For further perspective, a study published this month implemented a ketogenic diet (Richard A. LaFountain et al, Extended Ketogenic Diet and Physical Training Intervention in Military Personnel). That by itself isn’t noteworthy, as ketosis has been scientifically studied for about a century. What is significant is that it was the first time that such a diet done was done with military personnel. If you’re familiar with this area of research, the results were predictable which is to say they were typical. Military personnel aren’t essentially any different than other demographics. We all evolved from the same ancestors with the same metabolic system.
The results were positive as expected. Health improved in all ways measured. Body fat, in particular, was lost — relevant because the subjects were overweight. Benefits were seen in other aspects of what is called metabolic syndrome, such as better insulin sensitivity. All of this was accomplished while physical fitness was maintained, an important factor for the military. Going by what we know, if anything, physical fitness would improve over time; but that would require a longer term study to determine.
Ketosis is how I and millions of others have lost weight, even among those who don’t know what ketosis is. Anyone who has ever restricted their diet in any way, including fasting, likely has experienced extended periods of ketosis with no conscious intention being required — ketosis simply happens when carbs and sugar are restricted, and even commercial diets like Weight Watchers are quite restrictive along these lines. Other ketogenic gains often are experienced in relation to hunger, cravings, mood, energy, stamina, alertness, and focus. The point here, though, was weight loss and once again it was a glorious success.
That such studies are finally being done involving the military indicates that, after a century of research, government officials are maybe finally coming around to taking ketosis seriously. It’s understandable why drug companies and doctors have been resistant, since there is no profit in a healthy sustainable diet, but profit isn’t a concern for the military or shouldn’t be, although military contractors who provide the food might disagree (high-carb food is cheaper to provide because of high-yield crops subsidized for a half century by the government). If the USDA won’t change its guidelines, maybe the military should develop its own. A military filled with those of less than optimal health is a national security threat.
As for the rest of us, maybe it’s time we look to the studies and make informed decisions for ourselves. Not many doctors know about this kind of research. And if anything, doctors have a misinformed fear about ketosis because of confusion with diabetic ketoacidosis. Doctors aren’t exactly the most knowledgeable group when it comes to nutrition, as many have noted. And the government is too tied up with agricultural and food corporations. Any positive changes will have to come from the bottom up. These changes are already happening in a growing movement in support of alternative diets such as ketogenic low-carb, which is maybe what brought it to the attention of some military officials.
Government will eventually come around out of necessity. A global superpower can’t maintain itself in the long run with a malnourished and obese population. The healthcare costs and lost sick days alone could cripple society — even now most of the healthcare costs go to a few preventable diseases like diabetes. I’m willing to bet that when the next world war is fought the soldiers will be eating low-carb, high-fat rations made with nutrient-dense ingredients. Not doing so would risk having an inferior military. For-profit ideology only goes so far when the stakes are high.

Is U.S. Nutrition Policy Making the Military (and Recruits) too Fat to Fight?
from Nutrition Coalition
This year, for the first time since 2005, the Army fell short of its recruitment goal, according to the recent report, “Unhealthy and Unprepared,” by The Council for a Strong America, a group of retired generals and admirals. Obesity was largely to blame. Some 71% of young people between the ages of 17 and 24 fail to qualify for military service, says the report. These alarming numbers raise the disturbing question of whether the U.S. will be able to continue the luxury of maintaining an all-volunteer army in the future.
Another recent study, this one by the Rand Corporation found that some two-thirds of the nation’s active military personnel are overweight or obese. Topping the scale is the Army, with 69.4% of its personnel overweight or obese. But even the trimmest military branch – the Marine Corps – isn’t much better, at 60.9%. These numbers may be misleading, since “obesity” is defined by BMI (body mass index), which does not distinguish between whether extra pounds come fat or muscle—the latter being more likely to be the case in the military. Still, rates of 60-69% are disturbingly high. Since these folks are following the military’s exercise program, we certainly can’t blame them for shirking on physical activity.
It seems, in fact, that the U.S. military diet actually worsens health, according to an Army publication six years ago. Chanel S. Weaver of the U.S. Army Public Health Command wrote, “Even those Soldiers who are actually fit enough to deploy can face challenges in maintaining a healthy weight while serving in the deployed environment.”
In the article, Dr. Theresa Jackson, a public health scientist at the U.S. Army Public Health Command, states, “Literature suggests that fitness decreases and fat mass increases during deployments.” This is an astonishing fact: fitness declines in the military, despite mandated regular exercise.
This paradox could be explained by the growing understanding that exercise plays a relatively minor role in weight loss. “You can’t exercise your way out of a bad diet,” is the new common catchphrase among experts. Instead, the principal factor driving obesity, as the data increasingly show, is poor nutrition.
A look at the Army’s nutrition guidelines shows that they emphasize low-fat, high-carbohydrate foods. The Army recommends eating “…high protein, low-fat items such as: fish, beans, whole wheat pasta, egg whites, skim or 1 percent milk, and low-fat yogurt” while avoiding “items such as: fried items, high fat meats, egg yolks, and whole milk.” This guidance comes from the U.S. Dietary Guidelines for Americans (DGA), a policy that has been co-issued by USDA and US-HHS since 1980. The military essentially downloads these guidelines and serves food in mess halls to reflect DGA recommendations.
Ironically, this reliance on the U.S. Guidelines could well be the very reason for the military’s obesity problems. This diet tells the entire U.S. population to eat 50-60% of their calories as carbohydrates, principally grains, and just as a high-grain diet fattens cattle, a large body of government-funded science shows that a high-carbohydrate diet, for most people, is inimical to sustainable weight loss.
The argument that Americans don’t follow the guidelines is not supported by the best available government data on this subject—which demonstrates widespread adherence to the Dietary Guidelines.
New military study: “Remarkable” results among soldiers on a ketogenic diet
by Anne Mullens and Bret Scher
Those on the ketogenic diet lost an average of 17 pounds (7.5 kg), 5 percent of their overall body fat, 44 percent of their visceral fat, and had their insulin sensitivity improve by 48 per cent. There was no change in the participants on the mixed diet. Training results in physical strength, agility, and endurance in both groups were similar.
The researchers noted:
The most striking result was consistent loss of body mass, fat mass, visceral fat, and enhanced insulin sensitivity in virtually all the ketogenic diet subjects despite no limitations on caloric intake. Physical performance was maintained…. These results are highly relevant considering the obesity problem affecting all branches of the military.
[…] Although neither group counted calories, the ketogenic diet group naturally reduced their caloric intake while eating to satiety.
The most noteworthy response was a spontaneous reduction in energy intake, resulting in a uniformly greater weight loss for all ketogenic diet participants.
The military should lead the U.S. fight against obesity
by Steve Barrons
That advice, driven by the government’s Dietary Guidelines for Americans, has largely stuck to the familiar low-fat, high-carbohydrate diet that calls on us to cut meat, butter and cheese. Yet in recent years, the science has evolved, and it has become increasingly clear to people like me that fats aren’t the enemy. Indeed, as I ate more fat and reduced my intake of sugars and other carbohydrates like grains, I lost weight and became healthier.
Experiences like mine are now backed by a fast-growing body of science, showing carbohydrate restriction to be effective for fighting obesity and diabetes while improving most heart-disease risk factors.
For many, it’s hard to get past the basic assumption that the fat on your plate becomes the fat in your body. But the truth is that it’s excessive carbohydrates that turn into body fat — completely contrary to what Americans have long been told.
So why hasn’t the government’s dietary advice caught up to the science? According to a rigorous investigation in The BMJ on the dietary guidelines, the experts appointed to review the scientific evidence relied on weak scientific standards in their report and failed to review the most recent science on a number of topics, including optimal intakes for carbohydrates, saturated fat and salt. Most critically, the report relied heavily on observational studies in which researchers follow test groups over long periods of time. But even the best epidemiological studies, according to the BMJ, “suffer from a fundamental limitation. At best they can show only association, not causation. Epidemiological data can be used to suggest hypotheses but not to prove them.” This is science 101.
The U.S. military serves more than 150 million meals per year to its personnel, and when those meals are based on a government-advised, high-carbohydrate diet, our troops have a harder time staying trim and healthy. The Army’s own website warns people to stay away from high-fat meats, egg yolks and whole milk and advises “eating less fatty food for better overall health,” while encouraging a diet that includes pasta and bread. Making matters worse, service members usually have fewer options for avoiding these nutritional mistakes, especially on deployments when they often can’t cook their own meals.
Ditching carbs may be the key to military success in America’s future wars.
Top Pentagon officials say research has shown that human bodies in ketosis — the goal of the popular and controversial ketogenic diet — can stay underwater for longer periods, making the fat- and protein-heavy eating plan a potential benefit to military divers. It is one example of a rapidly growing trend as military researchers zero in on how nutrition and certain drugs can enhance how fighting men and women perform in battle. […]
But industries that specialize in the link between diet and performance are eager to engage in complex conversations about using cutting-edge science to optimize the human body while preserving basic elements of choice and individuality. The example of how ketosis — a biological process in which the body burns fat for fuel — could produce more capable military divers is one of the clearest examples of the 21st-century debate that now confronts the Pentagon.
“One of the effects of truly being in ketosis is that it changes the way your body handles oxygen deprivation, so you can actually stay underwater at [deeper] depths for longer periods of time and not go into oxygen seizures,” Lisa Sanders, director of science and technology at U.S. Special Operations Command, said at a high-level defense industry conference in Tampa late last month.
“That kind of technology is available today,” she said. “We can tell whether you are or are not in ketosis. We have really good indications of how to put you in ketosis. And we know statistically what that does to your ability to sustain oxygen.
“The problem,” she said, “is I don’t have the authority to tell people — swimmers, submariners, etc. — that they’re going to get themselves in ketosis so they can stay in the water longer. That’s an authority question, not a technology question.”
The controversial ketogenic or “keto” diet may be the future of the military, some defense officials say.
Service members, and Navy SEALS especially, may have to forgo beer and burritos for skinny cocktails and avocado salad (forget the tortilla chips) if a proposal from Special Operations Command gains momentum.
While a nutritionally enhanced future could eventually be put into effect for all branches, the SEALS and other underwater dive-mission specialists might be the first groups targeted for the change in nutritional guidelines. […]
Discussion of new dietary guidelines for service members comes at a time of growing concern about obesity in the military and its potential threat to readiness. […]
For the diet to be implemented laterally across the military, produce choices and meat quality at military dining facilities across the world would have to change significantly, not to mention the high-carb and sugar content of MRE’s. The popular pepperoni pizza MRE would be a thing of the past. Although one benefit of formulating a new high-fat ration is that it would be lighter weight to carry.
“You can carry even more calories because fats weigh less, which is an advantage,” said Kinesiologist Jeff Volek, a professor at Ohio State University’s Department of Human Sciences and author of the study.
