I haven’t read the article so I don’t know the context but it’s probably specifically referencing autophagy, which is very nutrient sensitive: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6321489/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6321489/ If you’re looking for the science, “autophagy,” “AMPK”, “MTOR” are probably good search terms to start with. Here’s a recent review/introduction on how fasting stimulates autophagy that you can scihub: https://www.sciencedirect.com/science/article/pii/S1568163718301478 https://www.sciencedirect.com/science/article/pii/S156816371... (if you just want PubMed access you can give this one a read: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5783752/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5783752/ ) and a couple more starting points (follow the citation chain) if you’re looking into molecular mechanisms: https://www.physiology.org/doi/full/10.1152/ajpendo.00008.2013 https://www.physiology.org/doi/full/10.1152/ajpendo.00008.20... or https://www.nature.com/articles/ncb2152 https://www.nature.com/articles/ncb2152
