A medical column reviews evidence that limiting meals to an eight-hour daily window may reduce gut inflammation and improve Crohn's disease symptoms, and cautions that promising LSD trial results for anxiety have not yet been published in a peer-reviewed journal.

A 12-week trial of 35 obese participants published in Gastroenterology found that Crohn's disease patients following an eight-hour time-restricted eating window for six days a week lost an average of 2.5kg, reported 40% fewer bowel movements and 50% less abdominal discomfort, while a separate Definium Therapeutics trial of 245 people with generalised anxiety disorder showed full-dose LSD reduced anxiety scores by 9.8 points versus 4.7 for placebo, though results were only available via press release.
