There has been yet another study showing that what the popular media and diet industry tells us about weight loss is just so much bullshit. You know all those infomercials insisting that if you get a shake weight or whatnot you will quickly develop toned arms, or rock hard abs, or buns of steel, or whatever they are promising because fat people only need to eat less/better and exercise to become thin?
Yeah, not so much.
Researchers recently studied a small population of hunter-gatherers living in the East African country of Tanzania, called the Hadza, and found out that their active, non-processed-food-eating lifestyle meant that “their total energy output is almost identical to that of today’s pudgy Westerners. This counterintuitive finding is explained by the foragers’ lower basal metabolic rate: they expend less energy while at rest, even when we compare people of the same size and age.”
The article went on to marvel that the “new findings seem to contradict popular beliefs that weight management is simply a matter of balancing what we eat with enough purposeful physical activity.” Obviously the author of the article is unfamiliar with the shitload of other studies saying the same thing.
London Mable, one of my awesome readers, recently sent me a link to a blog called Junkfood Science, which quoted:
“one of the country’s foremost obesity researchers, Jeffrey M. Friedman, M.D., Ph.D., head of the Laboratory of Molecular Genetics at Rockefeller University, New York, the “simplistic notion” that obese individuals can ameliorate their condition by simply deciding to eat less and exercise more is “at odds with substantial scientific evidence illuminating a precise and powerful biological system that maintains body weight within a relatively narrow range.” Our body shapes and sizes are, to a most significant extent, genetically determined. “The heritability of obesity is equivalent to that of height and greater than that of almost every other condition that has been studied,” according to Dr. Friedman. Someone genetically predisposed to obesity will become obese independent of their caloric intake even when it’s restricted to that of thin counterparts, he’s said.”
The knowledge that for most people fat is not voluntary, nor a simple matter of calories v/s exercise, has been out there for a long time. Wonder when it will seep into the public mind? Maybe when the diet industry don’t have a more than $60 BILLION profit riding on keeping the myths going, is my guess.
