Episode notes
Peptides Target Root-Cause Cell Signaling
- Peptides act as cell-signaling agents that treat root-cause dysfunction by modulating molecular pathways rather than only masking symptoms.
- Physicians need deeper cellular and molecular knowledge to use peptides effectively, beyond typical medical training.
Exercise Rewires Brain Metabolism And Mood
- Exercise balances key molecular pathways (AMPK, mTOR, NRF2) and improves mitochondrial function across neurons, astrocytes, and microglia.
- Muscle acts as an endocrine organ producing myokines like BDNF that cross the blood-brain barrier and improve mood and cognition.
Kickstart Fitness With Short-Term Metabolic Tools
- Use accessible interventions (exogenous ketones, small peptides) to create early wins that help anxious or depressed people start exercising.
- Then progressively build sustainable habits of sleep, exercise, and diet as the foundational treatment pillars.
