I did not mention "fasting" or "diet" or "weight loss".
Just condense your caloric input into a tighter window and walk more than zero miles per day.
It's silly to pursue fine grained, specific optimizations when the juiciest, lowest hanging fruit is stubbornly, inexplicably, left unpicked.
Edit: I’m referring to the “feeding window”
There is at least some research supporting the claim that time-restricted feeding inhibits the growth of cancer in humans: "In repeated-measures Cox proportional hazards regression models, fasting less than 13 hours per night (lower 2 tertiles of nightly fasting distribution) was associated with an increase in the risk of breast cancer recurrence compared with fasting 13 or more hours per night (hazard ratio, 1.36; 95% CI, 1.05-1.76)." https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4982776/
There have also been studies in mice: "Results and Conclusion: TRF had a dramatic effect, reducing tumor growth in obese mice fed a high fat diet (HFD) to levels seen in lean mice. Tumor growth and initiation was also delayed in the transgenic PyMT model of mammary tumorigenesis. Our results further suggest that the antitumor effect of TRF is at least partially mediated by reducing hyperinsulinemia, suggesting that this intervention may be effective in breast cancer prevention and therapy." https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6552025/
