What science finds
- 99 randomised trials: intermittent fasting gives weight loss similar to daily calorie restriction; no extra benefit for blood sugar. (Semnani-Azad et al. 2025, BMJ 389:e082007)
- 13 observational studies: mixed results on vegetarian diets and mood. This is a correlation; science has not shown that a vegetarian diet improves mood. (Iguacel et al. 2021, Nutrition Reviews 79(4) · source)
Limits, honestly
Not for: pregnant or breastfeeding women; children and teenagers; people with diabetes on medication; anyone with a past eating disorder. Ask a doctor first. Intermittent fasting is not magic.
Stop practising if
Stop or shorten practice and talk to a professional if you notice: rising anxiety or panic; low mood that lingers; feeling that you or the world is ‘not real’; flooding memories of trauma; several nights of poor sleep; hearing or seeing things others do not; thoughts of harming yourself. People with a history of psychosis, bipolar disorder or severe PTSD should ask a doctor before practising more than 20 minutes a day.
