BMI 27: The New Normal? | ConsultantLive

And then there is the “fat but fit” phenomenon which has been pretty well documented when it comes to benefit of glycemic control and blood pressure. So there are benefits to exercise that go beyond weight loss. The other variable is fat vs lean muscle. This was addressed briefly when the question of waist circumference was raised, which is definitely a risk factor in men.

Results of a large Danish cohort study place the BMI measure with lowest risk for all-cause mortality in the “overweight” category.

Why You Shouldn’t Exercise to Lose Weight, Explained with 60+ Studies DocNews

weightlossBy studying the Hadza’s lifestyle, Pontzer thought he would find evidence to back the conventional wisdom about why obesity has become such a big problem worldwide. Many have argued that one of the reasons we’ve collectively put on so much weight over the past 50 years is that we’re much less active than our ancestors.

Surely, Ponzer thought, the Hadza would be burning lots more calories on average than today’s typical Westerner; surely they’d show how sluggish our bodies have become.

On several trips in 2009 and 2010, he and his colleagues headed into the middle of the savanna, packing up a Land Rover with camping supplies, computers, solar panels, liquid nitrogen to freeze urine samples, and respirometry units to measure respiration.

In the dry, open terrain, they found study subjects among several Hadza families. For 11 days, they tracked the movements and energy burn of 13 men and 17 women ages 18 to 75, using a technique called doubly-labeled water — the best known way to measure the carbon dioxide we expel as we burn energy.

When they crunched the numbers, the results were astonishing.

“We were really surprised when the energy expenditure among the Hadza was no higher than it is for people in the US and Europe,” says Pontzer, who published the findings in 2012 in the journal PLoS One. While the hunter-gatherers were physically active and lean, they actually burned the same amount of calories every day as the average American or European, even after the researchers controlled for body size.

Is wellness working? | BenefitsPro

manwellnesssuitgetty-crop-600x338Indeed, the highest participation came for health risk and biometric assessments, which 48 percent of employees underwent. Organizations often offer employees lower premiums for doing such screenings.

Only 22 percent of workers participated in worksite diet or exercise events, while 8 percent took part in programs aimed at getting better sleep or quitting smoking.

The average employer offers $800 in incentives to employees for various wellness activities, but the average employee took in only $365, and 40 percent of employees earned nothing.

The Dark Side of Your Fitbit And Fitness App DocNews

1428230715893.cachedWhen David Sedaris purchased his Fibit last summer, this small piece of technology inspired him to walk after dinner instead of sitting on the couch. When his Fitbit died, however, walking became pointless without the steps being counted or measured. Sound familiar?

Two hours on the row machine, like Frank Underwood does, will not cancel out the pizza you ate during your House of Cards binge.

I equate using a fitness tracker or food calorie tracker as a marker of dishonesty with ourselves. We are missing a pivotal step: self-reflection. It’s really easy to buy a Nike Fuel band and wear it. It’s much harder, however, to get deep with yourself.

Fitness apps are a flawed, abbreviated version of this self-reflection process. They focus too much on the number of steps, calories, or distance traveled. Fitness tracking devices distract us from what really needs to happen: we need to look at ourselves naked in the mirror and have an honest conversation with our naked self about the status of our health. From a weight-loss standpoint, it’s critical. Then let’s unplug the TV, peel ourselves off the couch (if not get rid of both the TV and couch), and buy a few free weights and a yoga mat before throwing down for a fitness tracker. The cost is about the same, but the impacts couldn’t be more different.

One Twin Exercises, the Other Doesn’t – NYTimes.com

twin_studiesThe researchers were looking for young adult identical twins in their early- to mid-20s whose exercise habits had substantially diverged after they had left their childhood homes. These twins were not easy to find. Most of the pairs had maintained remarkably similar exercise routines, despite living apart.

But eventually the researchers homed in on 10 pairs of male identical twins, one of whom regularly exercised, while the other did not, usually because of work or family pressures, the researchers determined.

The dissimilarities in their exercise routines had mostly begun within the past three years, according to their questionnaires.

The scientists invited these twins into the lab and measured each young man’s endurance capacity, body composition and insulin sensitivity, to determine their fitness and metabolic health. The scientists also scanned each twin’s brain.

Then they compared the twins’ results.

It turned out that these genetically identical twins looked surprisingly different beneath the skin and skull. The sedentary twins had lower endurance capacities, higher body fat percentages, and signs of insulin resistance, signaling the onset of metabolic problems. (Interestingly, the twins tended to have very similar diets, whatever their workout routines, so food choices were unlikely to have contributed to health differences.)

The twins’ brains also were unalike. The active twins had significantly more grey matter than the sedentary twins, especially in areas of the brain involved in motor control and coordination.

Presumably, all of these differences in the young men’s bodies and brains had developed during their few, brief years of divergent workouts, underscoring how rapidly and robustly exercising — or not — can affect health, said Dr. Urho Kujala, a professor of sports and exercise medicine at the University of Jyvaskyla who oversaw the study.

Of course, the study was small and not a formal randomized trial, although it involved identical twins.

But Dr. Kujala said he believes that the results strongly imply that the differences in the twin’s exercise habits caused the differences in their bodies.

More subtly, the findings also point out that genetics and environment “do not have to be” destiny when it comes to exercise habits, Dr. Kujala said. For these particular twins, whether their genes and childhoods nudged them toward exercising regularly or slumping on the couch, one of the pair overcame that legacy and did the opposite (for better and worse).

The rest of us can do likewise, Dr. Kujala said. Even if the input from our DNA and upbringing urges us to skip the gym, we can “move more,” he said, and, based on this study, rapidly and substantially improve the condition of our bodies and brains.

The 3-Step Process to Determining Your Ideal Carbohydrate Intake

sweet potato friesThere’s been a lot of talk about the right amount of carbohydrates to eat lately. Laura Schoenfeld started us off with her article about the possible detriments of eating a low-carbohydrate diet for too long, and Chris Kresser followed this up with his discussion of the common misconceptions people tend to have about low-carb diets. They’ve done the heavy lifting here and provided lots of scientific evidence to back up cases where a higher or lower carbohydrate diet might be beneficial.
