Introduction
IGF-1 (Insulin-Like Growth Factor 1) has emerged as a hot topic in health and nutrition discussions, often linked to longevity, cancer risk, and metabolic health.
On one hand, IGF-1 is essential for growth, repair, and metabolic regulation; on the other, it is sometimes associated with disease processes, including cancer and cognitive decline.
For those intrigued by the intersection of nutrition, biomarkers, and disease prevention, IGF-1 offers an opportunity to explore how science grapples with these complexities.
Claims about manipulating IGF-1 through dietary changes — whether by reducing protein or adopting fasting protocols — are common. But does the evidence support these claims?
If you’re curious about IGF-1 and the relationships between diet, disease, and healthy aging, in this Premium-exclusive episode Danny and Alan discuss this fascinating topic.
