Dr. Rangan Chatterjee

Dr. Rangan Chatterjee (UK GP and media personality) and Dr. Tommy Wood (Cambridge/Stanford-trained neuroscientist and performance scientist) examine alcohol, caffeine, and sugar through individual-context and dietary-pattern lenses rather than universal good/bad rules. Recent population evidence has strengthened the public-health message that 'less is better' for alcohol even at low moderate intake (UK Biobank brain-volume signal); caffeine timing relative to sleep is now mainstream sleep-medicine guidance; ultra-processed-food evidence supports treating refined-sugar-heavy products as a broader category. The episode also covers continuous glucose monitor use (which can cause anxiety without clear behavioral benefit in non-diabetic users), exercise, and the protein leverage hypothesis. Both experts have substantial media profile and commercial exposure (Chatterjee through books, BBC, podcasts; Wood through performance-science consulting); the underlying scientific framing is generally well-calibrated.
