Claim summary · not a verbatim quotation
People need less sleep when following a ketogenic diet.
The finding
What the evidence shows
Studies do find that keto can improve sleep quality, change the mix of sleep stages, and reduce daytime sleepiness. That is not the same as needing less sleep, and a review of keto and sleep says high-quality long-term studies are still few. The speaker also said he did not know why, so this rests on personal experience. A controlled study showing keto dieters stay rested on measurably less sleep would flip this.
