The ticking clock is often used as a metaphor for life. But is a tick-tock approach to the advancing years an accurate way to measure the aging process? Dr. Joseph Antoun, a physician and CEO of the nutrition technology company, L-Nutra, believes a “biological aging score” is the best way accurately to assess our state of health. He says the human body has the potential to age more slowly than its chronological age, and health care should be based on a better understanding of how well our bodies are performing, from the inside. L-Nutra, based in Los Angeles, is a company founded by the longevity scientist, Dr. Valter Longo, to develop and market a fasting mimicking diet. In this LLAMA podcast interview, with Peter Bowes, Dr. Antoun explains the philosophy and science behind a dietary intervention that is designed to promote longevity.
