ADVICE

Cut Alcohol To Improve HRV And Slow Aging

  • Cut alcohol as a priority because even 1–2 drinks nightly lowers HRV and accelerates aging.
  • Shah used wearable HRV data to show consistent drops after drinking, linking alcohol to chronic stress load.
ADVICE

Avoid Ultra Processed Foods And Blunt Sugar Spikes

  • Avoid ultra‑processed and high‑sugar foods, especially liquid calories, because perimenopause raises insulin resistance.
  • Shah recommends fresh fruit, fiber, and post‑meal walking to blunt sugar spikes and protect A1C.
ADVICE

Pair Treats With Protein And Remove Yourself From The Kitchen

  • Use pairing and environment tricks to curb cravings: eat treats with protein/fiber and put portions in a small bowl then leave the kitchen.
  • Shah says walking away reduces repeated grazing and exploits dopamine patterns.
