I’ve read that the Apple Watch VO2max is accurate to within about 15% of professional testing. I use an Apple Watch Ultra (original), and since getting it in 2022 I began running regularly, running around 20-35km a week, with good consistency.
Since 1 October I have been using ChatGPT as a coach for my nutrition, and now my diet is puritanical whole foods, with zero cheat days since 1 October. An average meal will be sea bass, brown rice, tenderstem broccoli, avocado, kale, extra virgin olive oil, herbs, salt and pepper.
Whilst I feel so much better (never hungry, never lathargic), and recover much quicker, what I struggle to believe is that my VO2max had jumped from a low of 47.4, to 58.0 today, two months later, after a long plateau for a year.
This is an all time high for me, should I trust these numbers, and what might have caused this?
