Hill grew up in
Melbourne. When he was 15, his father a highly respected professor of Physiology had a heart attack in front of him at age 41. Hill wanted to find out what a heart
healthy diet looks like. Hill is the nutrition advisor for
Chris Hemsworth's fitness app,
Centr. In 2019, he opened a restaurant, Eden Bondi at Campbell Parade,
Bondi Beach. The restaurant was described as an "instant hit among vegans and non-vegans alike". It closed in December 2023. In 2021, Hill authored
The Proof is in the Plants. The book argues that a diet of at least 85% whole plant foods helps maintain a healthy weight and reduces risk of cancer and cardiovascular disease. A review by Seth Yoder of
Red Pen Reviews gave the book a high score for its evidence-based claims and scientific accuracy. The podcast still focuses on nutrition but has expanded to other lifestyle factors that impact well-being including exercise, mental health and sleep. In 2024, Hill released The living Proof Challenge, a zero-cost 12 week challenge to help people optimise important biomarkers to lower their risk of disease and live better for longer. ==Personal life==
