"We expected to find that these people are really active and to have high activity metabolic rates matched by high food intakes," says corresponding author John Speakman, a professor at the Shenzhen Institutes of Advanced Technology in China and the University of Aberdeen in the UK. "It turns out that something rather different is going on. They had lower food intakes and lower activity, as well as surprisingly higher-than-expected resting metabolic rates linked to elevated levels of their thyroid hormones."
- causi 4y agoMakes me wonder, if thyroid disorders can cause obesity, can thyroid-modifying therapy or exogenous thyroid hormones treat obesity?
- tapland 4y agoI've been on and off thyroid medication since my early teens and bounced about 40 lbs up and down during it. My hormone issues were first found because I gained weight while being a competitive young athlete. I think the same range is pretty common for people with certain other medications. The whole dieting discussion, all nutrition advice, kcal in/out goes out the window when your metabolism is a black box. Afaik there still isn't any study showing that any dieting works long term? So if we want to fight an obesity epidemic more needs to be done than to shift blame to affected individuals.
- lazide 4y agoCommon symptoms of thyroid disorders include obesity and/or excessive thinness (not anorexia per-se, but it can look like it), along with a cornocopia of other issues. Certain mental disorders (depression and anxiety) also highly correlate with obesity and/or underweight. A common treatment for ADHD (stimulants) often gets folks to a healthy weight that previously struggled on one side or the other. It’s a complex problem, with a lot of ever changing variables we have little insight into. Anecdotally, I know of several boomers that had serious thyroid issues likely tied to exposure to the Santa Susana Field Lab and Nevada nuclear testing. They were consuming milk and other products from areas contaminated by them at the right times. All the various plastics we’ve all been exposed to and other various chemicals are also likely doing something too. But also, the whole country has gotten dramatically more sedentary and media consumption focused, and the media keeps getting more and more anxiety inducing and alienating. As a country, we all need to ‘get out and touch some grass’ more too.
- Clubber 4y ago>All the various plastics we’ve all been exposed to and other various chemicals are also likely doing something too. Is this based on a study or something, or is it more of a reaction to all the news stories about that lately? (news peddles fear without anything to back it up typically)
- lazide 4y agoI don’t follow the news anymore, but there are boatloads of studies over the last several decades showing some plastics (and commonly used plasticizers) are Not Great in various ways, from hormone interference to cancers. Most of the more obvious offenders got banned or voluntarily phased out awhile ago, but new variants of many plastics come out every year, and large swaths of existing ones are known bad but don’t commonly get used in good contact anymore so we don’t think about it. One of those ‘we’ll probably figure out which one in the basket is causing what problems in a decade or two’ situations, and how bad a problem it actually is. Hopefully no thalidomide chirality level horrors, but who knows.
- giantg2 4y agoI'd imagine that thyroid hormone modifying treatments without thyroid dysfunction could lead to other issues.
