I've been walking every day and lifting weights 2x a week. I feel good so far but the hard part is doing it for years and through seasons (both literal and figurative).

VO2 max is also exercise dependent. If you trained riding bike for 3 months, then went to run down the street, your VO2 max would not transfer over.
My VO2 max from running definitely transfers to cycling. Doesn't mean I'm an amazing cyclist but at least cardio isn't my limiting factor.

It only takes a few months to make substantial gains in c-v fitness.
Define substantial. I find that incredible. EDIT: Now that I've seen the replies, I realize that this is from a very low baseline. I'm personally going to the gym four to five days a week already and my own cardiovascular fitness has not seen much of an improvement in many months.
Weird that people seem to assert that causality is not established? There are hundreds to thousands of studies that show that pretty much all markers for mortality and morbidity go down with excercise, i.e. put someone regulalrly on a treadmill for a couple of month and pretty much all health markers improve. People implying that the study shows only correlation really don't seem to understand how we establish causal…

Of course. I was responding to the time spent (out of ones day), opposed to calendar days of not eating. That said, people can make pretty rapid weight loss without eating. skip eating 1 day a week and that is 30 lbs a year for an average obese man. skip 2 days/week and that is 60 lbs/year.
> people can make pretty rapid weight loss without eating Your suggestion is not sustainable. A staggering 90+% of people regain all weight loss a year after their diet ends. Seriously, who is not going to eat for two days per week? Your mental health would be a wreck. Can you do it? I cannot.
I think conflating between mental health and eating is at the heart of the obesity epidemic. Nobody will die if they skip a few meals. They will suffer some moderate discomfort depending on how much they fixate on it.
I can go a week without eating and a few days is trivial. The longest a human has gone without food is 381 days and they lost 275 lbs

> Me and my bicyclist friends have never injured a head while falling down from bike Back when I did bike, I'd fall off and hit my (helmeted) head once a year or so. I was always thankful for having a helmet. Granted it was typically doing something stupid (jumping a curb or such), but still, I was thankful for having a helmet!

I'm a pretty proficient cyclist (lifetime mileage in the tens of thousands) but there have still been a handful of incidents where I've been very grateful to have had a helmet. It might be the case that helmets are a net negative for casual riders. But whenever I've done a spontaneous unplanned dismount at 20mph I didn't find that knowing how to fall helped me much.

Instead, people try to fix it with antidepressants, benzodiazepines or something else. It feels a bit like the US approach to pain management – instead of massages or physical therapy, some opioid pill is cheaper to prescribe.
I dislike this black n white rhetoric from both sides. "Just do some workout" - "no this doesn't work for me". Yes, workout does help, but mental illness is still real. Both sides should try to be more sensitive and more understanding in my opinion. I can't fix my social anxiety through workout. But I sure can feel better about myself when doing it and then approach those anxieties with more confidence, but the anxie…
Fortunately, this seems relatively simple to change (compared to other things with this magnitude of impact). It was a transformative experience to go from 40 VO2max to 57 (as reported by Apple Watch, and losing 30lbs on the way) over the past 12 months. The best part about it is that I didn't even have to give up anything - the extra energy I gained from 90-120 minutes of aerobics per day also had the effect of maki…
You should know that vo2 measurements that aren't performed via gas exchange or blood measurement are a complete guess. The other thing is the denominator of vo2 is weight. So losing weight without working out at all will increase vo2
It could have been named Vo5max and for me it'd have worked. In the real world, this number actually tracks pretty linearly with how much faster I'm able to climb a hill on a bike.
