This headline could not be more uninformative if it tried unless it was totally off topic.
Like probably a lot of people here, I read the headline and said to myself "no shit, of course diet matters" but then I read the article and the conclusion is actually pretty interesting: CICO is of course still king and that's not at all what this is about; this group did a mouse study and found that when they increased the amount of exercise available to the mice (and they started to exercise more), something happened that was not fatigue related that cause them to be MORE sedentary when they were not exercising, and in fact the increase in sedentary behavior almost perfectly counteracted the increased energy consumption from the running (they still ended up slightly net negative but extremely minor).
It's a short article and worth the read. Still a garbage headline.
- tgb 9y agoGood summary, but the difference was only that they would have burned 45% more extra calories from their exercise had they not reduced their other activities. If this is the same in humans, then you would just want to multiply your extra calories burned from your workout by about 0.7 to get how much you will have burned net accounting for your less movement throughout the day. That's not that far off from the naive estimate, so I'm not sure that this should really make a difference in our thinking about exercise and diet. (In particular, "extremely minor" seems far too strong a phrase and even "slightly" seems pushing it.)
- dljsjr 9y agoI based that on this quote: >These changes in how they spent their time neatly managed to almost counteract the extra calorie costs from running, says Daniel Lark, a research fellow in molecular physiology at the Vanderbilt University School of Medicine, who led the new study. And as this is a mouse study I make no comments on how to extrapolate that to humans. If this is behavioral and not biological then it might not translate at all.
- dang 9y agoIf you can get it into 80 chars we'll change the headline above. Edit: eloff wins for simplicity and good English.
- meatbundragon 9y agoNot OP, but how about: "Mouse study: more exercise induces more non-fatigue-related sedentary behavior"
- ac2u 9y agoExercising mice slack off so much afterwards it defeats the weightloss purpose
- niftich 9y agoExercising mice lessen aimless movement, nixing some of expected weight loss
- niftich 9y agonixing ~31% of expected weight loss actual + 0.45 * actual = expected 1.45 actual = expected 1 actual = 0.69 expected
- dljsjr 9y agoI was more complaining about the NY Times headline, I'm sympathetic to the idea of wanting the headlines here to match closely to the article itself. Some of the other folks here have commented with good ideas.
- criddell 9y agoIs 80 a hard-coded limit?
- dang 9y agoIt's a global variable in our code.
