That's the point of the study though. If you workout harder than your baseline, you will burn more calories than your baseline. But if you do that workout often enough, for various reasons you will return to baseline calorie expenditure. This means that if you want to lose weight consistently, working out is useless in that sense. You might see benefits for 1 month or 3 months or 6 months, but eventually your body ad…

How exactly can your body adjust that much though? There is some minimum baseline level of calorie burn to stay alive and keep your body temp etc. If you workout enough calories that exceeds the minimum baseline to keep you alive, the body can't adapt below that or adapt into the negative. For a 200 lb man, jogging for 2 hours burns like 2000 calories, so that's 12,000 a week for 6 times a week. What's the lowest a b…

For a 200 lb man, just jogging doesn't burn 1000 kcal/hr. You have to actually run at a pace of about 8:30 min/mi. People who can sustain that for 2 hours per day every day are not overweight in the first place.

For most people, a 1 hour moderate run is only about 1-2 cookies worth (and only half a Crumbl cookie). Even a marathon run might only burn 2000 calories . a chipotle burrito is 1600 . In other words, for 95% of people doing activity, they shouldn't eat any surplus if their goal is to maintain or lose weight. It's actually best to do most of your activity undernourished, as it helps develop true intuitive nutrition f…

I don't think a chipotle burrito is actually 1600 calories unless you do something non-standard. Probably 800-1100

Fair enough but people are eating those daily plus 2 more meals. They don’t need any additional food , even if they were running a marathon every day

Strava said I burned near 4k calories on my last marathon.

And most people eat more than 2 chipotles a day , even with no marathons

Unsurprisingly, the title is sensationalist and not representative of the study. The study compares energy expenditure across different economic groups i.e. western people sitting in offices versus hunter-gatherers in Africa, and found that difference in energy expenditure does not account for differences in obesity, so points to consumption as the likely reason. The sample dataset explicitly excluded 'athletes', so…

Absolutely.

This is one reason bodybuilders (the closest thing to professional dieters) will only do low intensity cardio -- walking etc -- when cutting weight.

High intensity cardio burns calories but increases appetite disproportionately. Albeit otherwise excellent for overall health.

I once worked a night shift stocking job just after college. I was in phenomenal shape without hitting the gym. I was at my lowest weight with a ton of lean muscle as a result of moving heavy loads and stocking paint every night. I also did the math at one point, and given the size of the warehouse I was probably walking quickly 8 miles during my shift. It became a chore to eat enough calories every day. Somewhere ar…

Reminds me of when I got my first job at 17...I worked at a large department/grocery store. My job primarily consisted of pushing karts from the corrals back to the store. In an 8 hour shift, I likely walked ~15 miles, with half of that time pushing up to a dozen karts. For lunch, I'd go to the McDonald's and get a Super Size (Since this was when that still existed) Double Quarter Pounder meal with a Coke. I'd chug t…

Polar explorers Fienes and Stroud were eating locks of butter and still losing weight on their sled pulling expedition. It was estimated that they were buring up to 11,000 calories a day.

People tend to vastly overestimate the caloric expenditure of activity, probably because it feels strenuous.

4 hard minutes on an assault bike will leave you gasping, but means next to nothing for energy expenditure.

I've lost 100 lbs twice. You absolutely can outrun a bad diet lol. It's just a LOT of exercise and counting all of your calories. A 1600 calorie bag of chips is 4 hours of cardio :)

Whenever the topic of weight loss comes up, I always make the same recommendation: Lift weights. Lifting weights increases your muscle mass. Muscle burns calories, even at rest, which raises your TDEE. (A bodybuilder will burn more calories sitting on the couch than someone who doesn't lift weights). For most folks (myself included) cardio sucks. You _could_ jog for an hour every day and burn x-hundred calories due t…

There are other advantages beyond just burning calories. Lean muscle tissue acts as glucose sink. When you eat you'll have more reserve capacity to store that energy temporarily in your muscles rather than triggering growth of adipose tissue.
