The study apparently only involved male participants. The control group consists of 6, the two treatment groups of 10 and 9 participants. The total N of the study is 25 participants. They conduct a one-way ANOVA on the interaction of time and treatment group indicators. I conclude that the study is woefully underpowered. I do not trust the apparent significance of their results.

Exercise doesn't result in changes in body mass (weight loss), unless accompanied with a diet. https://www.theguardian.com/science/2016/jan/28/study-reveal... .
I think it’s safe to assume that many inactive people start to exercise because they believe it will help them lose weight, however

Yes it can. I had an injury that prevented me from cycling for over a year and slowly gained weight. It all came off after resuming a normal routine without dietary changes.
> It all came off after resuming a normal routine without dietary changes. well, doh, if you eat the same and use less you will gain mass. It's not because (lack of) excercise, it's because diet not fitting lifestyle Excercises help in burning more calories so you can actually eat some tasty food from time to time without getting fatter and not going crazy from eating only low calorie stuff and that's about the only…
If I'm exercising regularly with sufficient intensity my appetite will go up, yes, but I still lose weight. For me, when training, keeping weight on is the dietary challenge. It's hard to eat enough!

If you're completely out of shape, going at HIIT level intensity is also risky. Better to build some kind of baseline before jumping into the deep end.
It is not risky but it is hard and I rather do low intensity running 60 minutes than 8 minutes HIIT.

#75In personal experience as a dedicated rock climber (traveling full time for half of the last 15 years), I can easily conclude that bursts of intense exercise accomplish a lot more for health and fitness than prolonged, more gentle workouts. Intensity readily builds muscle mass and coordinates muscle fibers, while fostering feelings of clarity and joy. It’s just the easier pathway to “being fit.” Climbers train for in…

#77The fact that 1 minute of high intensity exercise (in 10 minutes of lower-intensity stuff) is as good as 50 minutes of moderate-intensity training does really put things into perspective. What I wonder now is - what if you combine both? What if you do 50 minutes of moderate exercise but intersperse that with that same 1 minute of all-out sprints? Is there a bigger benefit, or is it inconsequential? And another questi…
It's probably far more beneficial to save the max effort for the very end. Fatigue and lactic acid concentration work in your favor that way
