"This means regular exercise (both strength training, ideally 3x per week, and cardio training that helps to improve V02 max like Zone 2 training)"
Actually, V02 max is best improved through High Intensity Interval Training (HIIT) like doing 400m sprints 8x with a couple minutes rest inbetween. V02 max is famous for being one of the best predictors of longevity.
Zone 2 training (light jogging) is important in tandem (80% of exercise ideally), especially for overall cardiovascular health and lowering heart rate.
Best thing I ever did for my health was start running (mostly jogging) 4-5 times a week. It's amazing how much your health can be improved with 4x 45 minute jogs (just 3 hours/wk). I can consume practically any caloric food for needed energy and all my health metrics have been substantially linearly increasing since I started.
"the stuff that’s not good for you: pasta and pizza and bread."
Tell that to the paragons of fitness in marathon running or olympic swimming. There are none of them on low carb. The best cardio health requires cardio exercise and cardio exercise requires carbs as energy. Of course if you're not going to exercise and are okay with 50th percentile health, ya carbs will hurt you then because youre not using them.
Is V02 max still the best predictor in people optimizing for it specifically above everything else, or only in people that train generally and have a high V02 max as a side effect?
He might be talking about zone 2 in a 3-zone model? Otherwise, I agree, zone 2 in a 5- or 7-zone model is not intense enough to provide VO2 adaptation.
