You Snooze, You Win: How a Lack of Sleep Can Hold Back Your Weight Loss

In grade school, we were told that “You snooze, you lose.” Now as adults, we know sleep is important, but when life gets hectic it’s often the first thing we cut out. That’s truly our loss. In fact, crappy z’s could be a big reason you aren’t losing weight. Here’s why.

One thing to keep in mind, though, is that despite an awful lot of money thrown at this by pharmas (it’s potentially the holy grail of a weight loss pill) while we have some interesting correlates on leptin and ghrelin and sleep and appetite, we haven’t really begun figuring out their mechanisms yet.

In fact, one of the more interesting bits of research that came out after that Chicago study was that that a population with untreated obstructive sleep apnea (OSA) has levels of leptin far above what their BMI should indicate, yet they are entirely resistant to its effects on appetite.

It’s also why any study involving leptin or ghrelin should be screening participants for potential sleep disorders, as the latter can wildly skew data. Unfortunately, almost nobody does that.
