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.

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.

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.

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.

Then why do so many people go to the gym, do 10k steps/day, intervals, etc. yet do not lose weight? Americans are arguably more active and health conscious than ever before as evidenced by the huge popularity of fitness content on YouTube, record number of gym memberships and attendance, the huge popularity of fitness apps, awareness of GMOs, food tracking apps, etc. yet fatter than ever too.

Because they don’t control their portions or eating habits. Take a look at the UK TV show “Secret Eaters”* which sets up secret cameras in and has investigators follow a different household every episode to estimate everything they eat down to the tablespoon of sauce. It’s an eye opening look into psychology. Lots of people think they’re eating 2K kcal or less but are in reality consuming 3-5K per day. * full episode…

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.

Perhaps you're not American, but Gallup reports that among those who drink soda in the USA the average daily amount is 31.2 oz

The article states the difference is small, but also notes “ The majority of the population exists in a range of 200-300kcal from each other”. All things being even 200kcal difference per day is about 20lbs per year attributed purely to metabolic difference. Now you can say to just eat 200kcal less per day, but those little differences on a daily basis add up.

> All things being even 200kcal difference per day is about 20lbs per year attributed purely to metabolic difference. As you gain weight, you burn more energy, even just being idle, so 200kcal doesn't means 20lbs per year (obviously so, as otherwise you'd gain 600lbs in 30 years). An extra 200kcals per day implies gaining extra weight until the extra energy you burn cancels it out, and then stabilizing there. IIRC th…
