Honest limits
What this study does not prove.
Sleep predicted results inside a weight-loss program, but this analysis does not prove that short sleep alone caused the difference or that sleeping longer guarantees weight loss.
Kris's practical takeaway
Here's what to do with it.
When progress stalls, review sleep alongside calories, movement, and training instead of assuming the person only needs more restriction.
Ways to use it
Safe ways to apply it.
A stalled plan needs a sleep check too
