Nutrition and fitness guidelines are evolving — and the gap between what the evidence supports and what is circulating on social media has never been wider or more consequential for clinical practice. In this session, Drs. Karl and Spencer Nadolsky bring complementary expertise in endocrinology, obesity medicine, and digital health to a timely review of the new nutrition and physical activity guidelines: what has changed, what the evidence actually shows, and how clinicians can help patients navigate a social media landscape flooded with conflicting, oversimplified, and often harmful messaging. From protein targets and resistance training recommendations to the clinical application of updated dietary guidance, this session equips clinicians with the evidence-based framework and practical language to cut through the noise — for their patients and themselves.
