Interesting, if deeply depressing, story in The New York Times Magazine by the paper’s health reporter, Tara Parker-Pope, about how bloody hard it is to lose weight — and keep it off:
While researchers have known for decades that the body undergoes various metabolic and hormonal changes while it’s losing weight, the Australian team detected something new. A full year after significant weight loss, these men and women remained in what could be described as a biologically altered state. Their still-plump bodies were acting as if they were starving and were working overtime to regain the pounds they lost. For instance, a gastric hormone called ghrelin, often dubbed the “hunger hormone,” was about 20 percent higher than at the start of the study. Another hormone associated with suppressing hunger, peptide YY, was also abnormally low. Levels of leptin, a hormone that suppresses hunger and increases metabolism, also remained lower than expected. A cocktail of other hormones associated with hunger and metabolism all remained significantly changed compared to pre-dieting levels. It was almost as if weight loss had put their bodies into a unique metabolic state, a sort of post-dieting syndrome that set them apart from people who hadn’t tried to lose weight in the first place.
“What we see here is a coordinated defense mechanism with multiple components all directed toward making us put on weight,” Proietto says. “This, I think, explains the high failure rate in obesity treatment.”
While the findings from Proietto and colleagues, published this fall in The New England Journal of Medicine, are not conclusive — the study was small and the findings need to be replicated — the research has nonetheless caused a stir in the weight-loss community, adding to a growing body of evidence that challenges conventional thinking about obesity.
I’m writing this post the day the story appeared and it’s already listed on the Times’ website as the fifth most e-mailed and eighth most-viewed story of the day.
“You see! It’s not just me!”
I can hear the frustrated bellow echoing across the internet, as fatties tell their skinnier/self-righteous family to back the hell off on the single easiest way to nag someone and make them really miserable. By telling them how to lose weight. “All you have to do is…”
I know because I need to lose weight — at least 30 pounds — and my father never lets me forget it. When I went out to British Columbia last year to put my mother into a nursing home — she, a former model with wrists the diameter of twigs — said “You’re fat.” Nice.
Two years ago this month I went to a nutritionist who put me on a vicious diet. No sugar of any form for a month. No carbohydrates or fruit for the first two weeks. I measured everything I ate with measuring cups and spoons. I drank a lot of water.
Yes, it worked. I refuse to get on a scale but I know my body — and see how my clothes fit. I shed 15 to 20 pounds within four months. I looked and felt great. Worried neighbors stopped my husband to make sure my weight loss was benign.
And then….why, yes, the weight came back on.
No, it didn’t creep up on me in my sleep. It showed up in the ways it does for all of us who weigh more than we should: through my own choices, of dessert, beer, the occasional cocktail, gooey French cheese.
I have no tidy answers on the battle between sensual enjoyment of a wide variety of food and drink, to me one of life’s great gifts, and being lean, taut, ever-vigilant for every stray calorie, exercising every day for hours to make sure the flesh is vanquished. My fridge contains the Holy Grail of 0 percent fat Greek yogurt. I eat it every day — and am sick to death of cold, wet, sour — but healthy! — nutrition.
There is a terrible, sad irony that millions of people worldwide are dying of starvation as the rest of us freak out over calorie counts and portion sizes.
Have you gained weight — and lost it — and kept it off?
Do you find it difficult?
