Tracing lactate and its functions in adipose thermogenesis Click on the article title to read more.

Is it primarily fueling thermogenesis? And what about its potential role as a hormone-like metabolite? Check out our piece below discussing these and several other unanswered questions about lactate and adipose thermogenesis 👇2/4 physoc.onlinelibrary.wiley.com/doi/10.1113/...

Circulating lactate is being taken up by cold-activated thermogenic adipose tissue in mice - but why? 🔥 Despite 4 decades of research on the role of lactate in brown fat, we still do not really know what lactate is doing inside this tissue 1/4 - source: physoc.onlinelibrary.wiley.com/doi/10.1113/...

Framework for the pharmacological treatment of obesity and its complications from the European Association for the Study of Obesity (EASO) - Nature Medicine Obesity and associated complications can be managed by obesity medications, prompting the revision of criteria for the diagnosis and staging of this disease.

The other end of the weight spectrum: Very thin people Researchers are exploring why some individuals are naturally super-lean and may struggle to gain weight. The causes of such constitutional thinness offer clues to the physiology of weight control.

As the world focuses on its billion-plus obese citizens, there remain people at the other end of the spectrum who are skinny, often painfully so, but don’t want to be. This recent @knowablemag.bsky.social article explores the “real enigma” of a condition. knowablemagazine.org/content/arti...

But there are also people that seem to eat more than they burn. The observation that certain individuals with constitutional thinness remain weight stable while seemingly eating more calories than they expend might be explained by increased loss of calories in the toilet 💩 6/8

But what might explain weight gain resistance in people with constitutional thinness? For some thin people,

Physiological protection against weight gain: evidence from overfeeding studies and future directions | Philosophical Transactions of the Royal Society B: Biological Sciences Body weight is under physiological regulation. When body fat mass decreases, a series of responses are triggered to promote weight regain by increasing food intake and decreasing energy expenditure. Analogous, in response to experimental overfeeding, ...

The numerous anecdotes and stories appearing in this network illustrate that:

1) Weight stigma hits both ends of the BMI spectrum!

2) People with thinness might also help us improve the treatment of other cardiometabolic diseases! 4/8
