Just ran across this article on Medium by the notorious Dr. Jason Fung, and...wow. Not great science here https://medium.com/@drjasonfung/weight-loss-benefits-of-green-tea-d665b5584325 …pic.twitter.com/vSp6a1C7pj

Anyway, the article then goes on to talk about a 2009 non-systematic review/meta analysis and how it demonstrated that green tea is effective for weight losspic.twitter.com/Q3rvOJUyO2
Rather than go into detail about why this 2009 review wasn't great (spoiler: it was pretty bad), I'll just go to a more recent Cochrane review on the subject It found no benefit http://www.cochrane.org/CD008650/ENDOC_green-tea-for-weight-loss-and-weight-maintenance-in-overweight-or-obese-adults …pic.twitter.com/Sjo2WRamIb
There is then a lot of discussion in the article about catechins, caffeine, and Asian vs Caucasians, but honestly why bother. If the best evidence indicates no difference between green tea and placebo...
...then any theories about WHY green tea causes weight loss are pretty much worthless. Because it doesn't.
So, essentially, Dr. Fung appears to be extrapolating from one awful study and a decade-old, out of date non-systematic review to make claims for green tea as an obesity preventative
In other words, he's claiming that green tea can make you lose weight using what I would describe as terrible evidence
When you look at GOOD evidence, it appears that green tea does nothing for obesity at all
Whoah, those weight and BMI numbers have some funky within-subjects action. @sTeamTraen
Huh I didn't even notice. The numbers do look oddly similar now that you point it out
