I went from 194 to about 153 lbs. last year, and have held my weight steadily between 152 and 159 lbs. ever since. That said, what is considered a healthy weight varies between individuals, and with genetics, lifestyle factors, and environmental influences, it’s hard for me to make any sweeping judgments about body size, health, weight loss, and your average person’s experiences. I’m inclined to be skeptical about this study’s conclusion for many of the same reasons Cory Doctorow is.
Here’s a CBC science piece quoting several obesity experts argues that long-term weight loss is almost impossible, saying that (uncited) meta-analyses of weight-loss intervention found that in the 5- to 10-year range, most weight-loss was reversed. According to Tim Caulfield, who holds a Canada Research Chair in Health Law and Policy, this is an open secret in scholarly and scientific weight-loss circles, but no one wants to talk about it for fear that it will scare people off of healthier eating and exercise regimes, which have benefits independent of weight-loss.
I found the article frustrating. While I am willing to stipulate that the data on long-term weight-loss suggests extreme difficulty, I wish the journalist had found biologists or doctors to discuss the issue, and had cited actual, specific research to support the claims made, which would make it easier to parse the nuances in the piece. It’s not that I think that interdisciplinary lawyers with an undergraduate science background have something to say on this
