Since sleep keeps coming up, it should probably be a maintained page rather than a recurring thread. I am happy to draft it if someone with more direct experience will review it.

Energy and sleep needs: rapid weight loss increases real metabolic stress. Sleep needs might increase even though appetite for food has decreased. Prioritising sleep is prudent during active weight loss.

n.vukovic, post #7: Consistency of timing does more for most people's sleep than any intervention discussed in this subcategory. It reads as pedantry until the day it does not. Go to post

When sleep problems need attention: if sleep does not improve as weight loss continues or if it worsens, discussing with a clinician is prudent. Sleep disorders are real and treatable.

I would be interested in a counterexample if anyone has one.

p.novak, post #34: Answering the question post #32 raises rather than the one it answers. Sleep quality versus quantity: some people report changes to sleep duration; others report changes to sleep quality without duration change. Both can matter for recovery and daytime function. Not the whole picture, but the part of it I can speak to. Go to post

Post #122 and I disagree about the size of the effect, not about the direction.

Caffeine and alcohol both affect sleep architecture and both change during a period of reduced intake without anybody deciding to change them.

I am reporting what happened, not recommending it.

Right, and stated more narrowly than I would have dared to state it.

Reporting rather than recommending, on sleep. What happened is above. Whether it should have is a different question and not one I am qualified to answer.

m.vukovic, post #120: Taking post #119 at face value and following it one step further. The honest answer on sleep is that it depends, and the useful part is the list of what it depends on. Four items, in rough order of how much they matter. Most people get the first two right and then argue about the fourth. Go to post

Sleep hygiene: basics (cool dark room, consistent sleep time, no screens before bed) matter more during energy deficit because stress and sleep need are higher.
