Gameplan:

  1. go into the woods.
  2. find and eat wild berries.
  3. fight locals bears to defend secret berry patch.
  4. Get shredded one way or another.
  5. ???
  6. profit.

Theyre actually freeze dried blueberry powder donated from the Wild Blueberry Association of North America. I'd not only take this study with a grain of salt, Id buy a stake in a salt mine:

>This was a non-randomized, quasi-experimental, free-living trial.

It was 11 people, aerobically trained, that they saw three times over the course of a month. For two weeks they ate whatever they wanted, but were asked to avoid eating a whole bunch of things like red wine, green tea, and any fruits and veg with dark or bright colors -- but to also eat the freeze-dried blueberry powder. They also changed their fluid intake over the few days leading up to testing...

In some, their diet changed quite a bit over the two weeks -- with the blueberry powder then becoming 30% of their carb intake.

It goes against a larger study that did it for 20 days and found no effect (using tart cherry juice) for these compounds with recreationally-active adults, but their thought is it's because they weren't at the same athletic level (this study removed participants who couldn't hit certain cycling metrics, even if they thought of themselves as active) or because they used a different exercise protocol... This study had people getting up to speed then stopping quite a bit for tests (like every 10 minutes IIRC). I'll leave that as an exercise to the reader as to why that could change things...

Weirder, this study introduced an overnight fast of 12 hours before the exercise. We know from previous studies that not eating for a period of time and then exercising hard will increase fat oxidization. If you can see how that could end up with weird results with only 11 people...

So yeah, a salt mine.

Edit: typos

Edit 2: Pointed out some strangeness with the authorship in another comment here.

Yeah exercise is a lot more important for your mental and physical health than it is for your weight. If you look up calories lost by exercising you quickly realize it's not really going to help you with that. But it might make you a more disciplined, healthy person who is more easily able to enjoy their life and do the things they want, which helps with the mental battle of weight loss.

I think the only other thing besides caloric restriction that's effective is probably stimulant/appetite suppressant use.

Good points. It would also be helpful to study whether it’s actually the blueberries or if eating anything healthy before a workout increases fat burn. Compare it to nothing, pre-workout, control doses.

In addition, I would love some future research into timing of the snack - whether delays between eating and beginning the work out matter.
