So if I activate this tiny muscle in my calf for a while my metabolism will be up for hours? And where all that added energy will go? I don't know a thing in this area but I know that when something looks too good to be true, it probably isn't.

Info is in paper and supplementals, but in short, the protocol was that participants did the spu's for either 130 or 270 minutes each day, with 50 contractions a minute. It's a work out.

No I think what they’re saying is if you do this exercise for hours while seated, you will have the increased metabolism and its benefits the whole time without getting tired.

> when something looks too good to be true, it probably isn't.

Is that a typo or are you a very lucky individual?

>> It probably isn't [true].

I think they mean, when something looks too good to be true, it probably isn't [true] (though that's not how the phrase is normally used, of course).

It's definitely one of those phrases that makes more sense spoken aloud.

Maybe you just have elevated mood and energy levels for a few hours? One of the nasty parts of dieting is that you can cut calories and not lose weight, just have less energy and feel worse. Probably not as relevant if your obese but cutting calories leads to some other effects than weight loss when your already lean.

Conversely if your weight is stable you might be able to add 500 calories with no ill effects, just more energy, faster recovery etc. It would be great if it was just formulaic like your post implies but it isn’t.

Heat, obviously. Thermogenesis.
