activity levels almost certainly. uni it's not impossible you were walking over 12k steps a day. that's 3-400 calories over the average american's daily steps of 4000.

That's also completely canceled out by enjoying a single 32oz soda. Walking a lot and having a bad diet rarely even each other out. And it's so easy to cancel it out I don't think most people realize. A brisk 2km walk burns less calories than are consumed when eating two regular Oreos.

  • I wouldn’t be surprised if most thin people who claim to eat lots of junk food actually just eat a lot less regular food. In other words, they don’t eat many calories, but the calories they do eat are junk.

    • I would say this was partially true in my case. While I ate badly, I didn't eat huge portions regularly. I also didn't eat breakfast regularly then (and often don't now either). In college we got fish and chips takeaway once it twice a week,and while it was definitely the worst kind of junk, I would be full quicker than others. That said, I regularly put away a quarter pointer, portion of chips, fizzy drink and a cheese and onion pie (deep fried cheese basically, and amazing). And not an ounce of fat on my body.

  • Strava tells me I burned 3,3000 calories this morning on my (4 hour)100km bike ride. About the equivalent of drinking 2 cups of melted butter, or eating 50 pounds of lettuce. When I'm doing exercise like that regularly it's hard to eat enough.

    • Strava’s calorie estimation is awful.

      Depends on the elevation gains in your 100km ride but I think that 3,300kcal for a 100km/4h ride is generous.

      800kcal/hr is hard work and keeping that up for 4h is even harder. 25kph does not sound like 800kcal/hr unless there was some reasonable elevation gains. I’d expect at least 1000m elevation gain over that 100km for those numbers to at least approach something sensible. If it was a flatter ride than that then Strava is just lying to you.

      But, yes, long distance cycling is an awesome way of burning calories. When I used to do Brevet/Audax riding I was the closest to my old teenage weight as I have been in the last ~30 years.

    • That’s more than an order of magnitude more calories burned than walking 12k steps.

    • Strava is probably wrong. Even if it's right, it's not like this can continue forever. At some point, the weight loss will stop despite Strava showing a deficit. So either you have to eat less or exercise even more.

    • 25km/h is the regulatory max speed of e-bikes around here and you averaged that. Most people would take years of training to get to the point of being able to exercise like this.

  • While this is certainly an argument for “how do I lose weight” the relevant part here is that the asker wondered why they started gaining weight, which makes a reduction in daily calorie burn relevant if caloric intake remained roughly consistent. That is a lot of ifs, naturally.

  • 32oz is a ton of soda tho.. Even when I was a teen at 6'4", 32oz of soda would be a sickening addition to a meal.

  • If you think drinking a litre of soda is no big deal I would encourage you to rethink. 400 calories with no nutrition is a lot.

  • It is even worse than that. The conversion rate of activity to net calorie loss is not 1 to 1 . It can be zero or even negative, at least based on my own experience and other people. You see people on Reddit subs do 10k steps and tons of walking, hardly lose any weight. It's all about not overeating.

    • Walking is great for many reasons, but 10K steps isn't much. It would be silly to expect much weight loss from that. And most people significantly understand their caloric intake.

    • One of the problems is people naturally adjust their activity levels after exercise. After a two hour bike ride they will spend the evening on the sofa. It seems we naturally adjust without consciously thinking about it.

As a student, I used a bus to get to school. As an adult, I walk by foot, more than an hour a day. Also, I didn't exercise in my youth, and I do now. Yet, it is now that I am fat.
