2 hours a day is a ridiculous amount

Why is two hours ridiculous? I find most people who devote themselves like this enjoy the process. If they enjoy it, it objectively improves their body, and they have the time - why not?

I definitely waste more time during the day than that lol.

Happiest and most productive Ive been was when I was skating, riding a bike, dancing etc for hours every day.

It's also absolutely amazing for mental health. It's a shame it isn't considered a first line of treatment for mental health because it's super effective (and free).

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.

Yep exactly this. The thing is we are now so removed from exercise (and healthy living in general) as a society - take the car, take the elevator, sit at your desk the whole day and then fall asleep in the couch at home. And paradoxically this lifestyle makes us so tired and energy depleted, that even the thought of starting to exercise seems ridiculous to many. This is making it super hard for many people to start exercising and persist, it seems like everything in modern society is geared to make us couch zombies - so no surprise we have high levels of obesity, anxiety, depression and what not.

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.

Not a source, but it tracks for me. Walk, jog, or run daily and you will have massive CV improvement from baseline in 3 months. people can and do go from being exhausted walking to their car to being capable running many miles in an incredibly short time. The typical human body is very responsive when pushed.

The heart, lungs, and muscles get strong fast. But the bones and tendons take more time. It's best to give them time so you don't wind up with shin splints, etc.

The relationship isn't linear, you can see in https://bjsm.bmj.com/content/54/20/1195#sec-16 that above 2200 MET-minutes/week there is increased cancer risk which outweighs the cardiovascular benefits. Now admittedly it is a very weak correlation, and MET measurement is imprecise, but I think it is safe to say that there are risks associated with over-exercising and while being in shape is good, being a ultra-maratho…

Luckily, very few people are in danger of extreme fitness. That is what the word extreme means.

indeed, a lot has changed from when we lived on rural farms doing manual labor. People aren't going back to the farms, so we need to adopt new behaviors and norms around self control. There is simply no viable alternative.

I would suggest that in the next 5 years or so if ozempic and others don't turn out to be cancer causing or have more than awful side effects that we'll see a large drop in obesity, as obesity isn't an easy thing to change. Likely other competitors will come along and use a similar mechanism and Novo won't be able to charge $1000 a month for it any longer allowing 80-85% of those who are overweight to give it a shot.

As I understand, ozempic only helps you lose up to 15% of your body weight. Most overweight people are much more than 15% overweight!

Over the past 11 months, I've lost 122lbs, from 330lbs to 208lbs. (May 30, 2023 - Today) For the first 2 months, cardio was not part of it. Really focusing on diet, reintroducing myself to portions of Whole Foods to hit macro goals. Really focusing on vegetables and protein, large quantities of low calorie foods that digest relatively slowly to keep me satiated for long periods. They're also quick to digest. I was al…

Congrats on the progress! > It's also a myth, perpetuated by highly trained athletes that you cannot gain muscle and do cardio, or that you cannot do these things while in a caloric deficit. I think it's more accurate to describe this in terms of definitions: "gains muscle while in caloric deficit" is possible for the untrained/beginners. > For the first 2 months, cardio was not part of it. It's really easy for bad d…

Couldn't agree more, at least on the strength front (I focused on that for 6mo 1.5 years ago) - Just those basic lifts will massively improve your muscle, and a lot of those improvements persisted despite doing very little strength work over the last year.

Anything is better than nothing, and many of the benefits are going to persist in some form for quite some time. I did lose some strength, but I'm still on the order of 1.5-2x as strong as I was before I did any work at all. Never mind the confidence strength training gives you when it comes to just doing basic stuff and knowing you aren't going to hurt yourself.

I think it's valuable to turn things into regular habits, but it's also worth noting for those who have this idea that it's a waste (because they'd rather be doing something else, and they don't want to work out for the rest of their life) - 6 months of basic (but hard, proper) workouts will pay dividends for probably forever.

Exercise (and sunlight!) are proven treatments for mild to moderate depression. It's probably not all you need, but it's a very good start. Exercise does nothing for severe depression.

Agreed, but mild to moderate depression is the majority of people with mental health issues - that's where we should start. Also , I suspect it will also help a lot in severe depression but its hard to get someone with severe depression to exercise - in that case meds should be the way to go.

It can take months to go from obese to not obese through calorie restriction

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 struggle with anxiety and have below average HRV and VO2max. I started jogging a month or so ago and have definitely seen an improvement in my mental health.

I love hearing this. If you'll keep at it you'll see your fitness and VO2max explode up so don't worry about it. Do some easy miles a few times a week during the first few months, just keep at it and be consistent.

I am disappointed by how poor primary care is in the developed world. It could easily be made better by including a VO2Max test and a DEXA scan every few years. On my own dime, I took both (cost was ~ $150 total from a private provider) and the DEXA scan revealed I carried too much visceral fat and my cardiovascular fitness was only average, things that never came up in my yearly physical. The same applies for basic…

For better or worse (worse), people don't go to the doctor for lifestyle analysis and rarely take lifestyle advice from their doctors. They go to their doctors to know when to start medical interventions. Even simple waist-to-hip ratio assessement would be a big win for identifying lifestyle concerns, but neither that nor the far more involved VO2Max and DEXA rests are going to become standard unless they becoming a…

Who wants lifestyle advice from an American doctor? If they find out you biked to their office, 9 out of 10 of them will scold you about helmets, in the exact same counterproductive way as Americans of every other occupation.
