The majority of weight is lost through respiration, that's the C in CO2. Exercise is great for health, and does help weight loss. But diet is the only thing that is going to resolve this. You consume far more calories in a regular sized Milkyway then you're going to burn exercising in 50 minutes that's for sure. Here's a chart of just those tiny "fun sized" Halloween candies. https://www.popsugar.com/fitness/What-Tak…

A large person will burn way more calories from simply going for a walk than a small person. I'm 6'5', 270 lbs, went for a 3 mile walk this morning, and burned maybe 460 calories. A person weighing 135 going for the same walk would burn 230 calories. In either case, me and 50%-me would have burned off a 230 calories candy bar.

I see a lot of comments from people I suspect have never struggled with weight loss here.

"Put the fork down" is easy advice, but for many it's a lot more challenging than it sounds.

For me, and I suspect a lot of people, focusing on exercise first is the key. I can plot the number of miles I post on the bike against my weight. Of course I absolutely do more than 300 minutes a week on the bike.

Diet is super important, likely more important that fitness, but diet is vastly more difficult for me. Also, when I'm working out regularly, my diet naturally shifts. If I'm sitting at my desk or on the couch for weeks at a time, food intake increases.

I'm sure if I could ever properly reign in my eating I could change this, but I've tried so many times and it never works. Working out on the bike does, and as I mentioned above, the intake adjusts correctly when I do it.

The article argues that exercising reshapes your dietary desires in a positive way.

Note that the article describes "walking moderately for 30 or 60 minutes". I'd be curious to see how high-impact exercise like running would make a difference.

It's hard to say although last time I looked into this literature really deeply, it seemed like distance was kind of the key. That is, most health gains could be equated by distance in that whatever gains you'd get from 1 hour of walking, epidemiologically speaking, would be accrued by running the same distance that's covered in that hour of walking (on average or whatever).

Work = Force * Distance.

Practically you're more efficient walking than you are running, but walking is nearly as effective as a calorie burner as running, it just takes longer.

Five hours a week is way more than most people who work and have a family can do. Even if you find the time, you might be quite tired and that also eats into your time budget.

Also, you might spend maybe 200cal lightly cycling during a zoom call. You will get that back in a few seconds of eating, if you choose something heavy like a chocolate bar. Your best bet then is to just control the incoming calories, because even an all-out workout of an hour will do you maybe 800cal if you're a bit bigger and stronger than me, and even if you did that you'd feel super tired for a long time after and maybe even decide to eat up that amount again.

In my case, it was all about calories. I've done this, and a friend did this as well: get one of those electronic scales that's got a couple of decimals on it, eg says 92.15kg. Then you can get used to understanding how much weight you lose while sleeping, how much you are carrying as pee and poo, and how much a meal tends to weigh. This will tell you how much you actually weigh, because you can take out the noise.

Have a look at an online calculator that tells you how much you should be eating for a given target. Find out the calories in everything you eat, and eat that budget.

I did this, and amazingly, the weight loss was just as expected. Thermodynamics seems to work.

That's 50 minutes per day with a day off per week. Two pomodoros. E.g. cardio in the morning and resistance in the afternoon. That sounds like a lot to fit into a busy life, but a low price if it's all it takes to emulate the health of the hunter gatherers we evolved from.

Only because the purpose of modern life is to work rather than working to live life. There’s no need for people to work 8 to 10 hours a day, and commute 30+ min in an automobile. Rather than use our technological efficiencies to improve quality of life now, we use them to compete with others to increase probability of securing quality of life in the future.

We only use them to compete with others because others use them to compete with us, keep up or starve. The equilibrium is whatever people are willing to do, strangely meaning that nobody has a choice in this thing that we’ve all chosen.

No idea how to switch to new dynamics so that defecting (in the sense of working less) is the stable equilibrium.

Earlier quoted context omitted.

Walk to work instead of driving?

Pre-COVID and WFH becoming normal, I had a short commute. Only 6 miles. Many places, walking to work is a joke.

Well, 6 miles sounds about right for a 30min bike commute to work. Do that each way and you’ll have a daily hour of exercise without having to step foot in a gym.
