What Is Metabolism?
Metabolism is a subject covered in depth across 3 podcast episodes in our database. Below you'll find key concepts, expert insights, and the top episodes to listen to — all distilled from hours of conversation by leading experts.
Key Concepts in Metabolism
Peptide legalization (fda reclassification)
The process by which the FDA moves specific peptides from Category 2 (research chemicals, limited use) to Category 1 (legalized for broader use), making them more accessible. This episode highlights the FDA's consideration of doing this for seven peptides in July.
Bpc 157
A peptide specifically linked to and discussed for its significant role in general tissue 'repair and injury' recovery.
Tb500
A peptide described as improving 'blood flow to an injured area' and sending necessary cells for 'rebuilding that tissue matrix' after damage.
Mc (mitochondrial peptide)
A peptide shown to induce 'upregulation of basil metabolic rate,' improve 'V2 max and your exercise tolerance,' and increase ATP availability, earning it the moniker 'exercise in a vial.'
Angiogenesis
The physiological process of forming new blood vessels from pre-existing ones, which is a key mechanism linked to peptides like KPV for tissue repair.
Cognitive peptides (cax, dip, epiallon)
A group of peptides discussed for their collective ability to 'affect cognitive function,' with specific mentions of CAX for thinking improvement and DIP/Epiallon for sleep and recovery.
What Experts Say About Metabolism
- 1.Perception is the process by which the brain transforms external reality into electrical signals to represent the world and guide behavior, distinct from mere sensation or detection.
- 2.Taste is initially hardwired with innate preferences (e.g., liking sweet, disliking bitter), but this system is highly plastic and can be modulated by learning and experience throughout life.
- 3.The gut-brain axis, primarily mediated by the vagus nerve, plays a critical role in driving our preferences and cravings, especially for sugar, independently of taste perception.
- 4.Artificial sweeteners do not activate the gut-brain circuit that recognizes glucose, meaning they do not satisfy the deep-seated, post-ingestive craving for sugar in the same way as actual sugar.
- 5.Obesity should be viewed as a disease of brain circuits and the nervous system, as the brain acts as the ultimate 'conductor' of physiology and metabolism.
- 6.Highly processed foods can hijack evolutionarily dedicated brain circuits for essential nutrients (sugar, fat, amino acids), leading to continuous reinforcement and overconsumption.
