Dr. Oz is getting called out again over a "magic weight-loss cure" he touted on his TV show ... this time in a class action lawsuit.
The suit is all over weight loss supplements containing Garcinia Cambogia ... which is green coffee bean extract. They're sold by a company called Labrada, and Dr. Oz covered the products on an episode called "Five Biggest Fat Busters for Five Body Types in Just Five Days."
The suit, filed by a consumer on behalf of all purchasers, says Oz described Garcinia Cambogia as a revolutionary fat buster which "could be the magic ingredient that lets you lose weight without diet or exercise." The suit says the "Oz Effect" caused sales to skyrocket.
Oz already had to testify about this product for a Senate panel in 2014, and during the grilling he leaned on evidence from a scientific study. But the lawsuit points out that study has since been discredited.
According to the suit, "all credible scientific evidence" shows Garcinia Cambogia simply doesn't work. The plaintiffs are going after Oz, Labrada, Harpo Productions and others to get their money back plus damages.
A rep for Oz's show says the lawsuit attacks his right to free speech and, "As we have always explained to our viewers, the Dr. Oz Show does not sell these products nor does he have any financial ties to these companies."
Answer: Hemsworth ... after he dropped major lbs for his starring role in Ron Howard's upcoming "In the Heart of the Sea."
Hemsworth plays a sailor stranded at sea in the Moby Dick-inspired flick, so he obviously got way into character. He posted the throwback pic from the set saying he wouldn't recommend the diet to anyone.
Hard to believe that's the same guy who plays Thor, but the good news is Chris is back to his standard beefy bod since filming.
Oprah is at the top of the weight loss totem pole, with so much swing even companies in head-to-head competition with Weight Watchers are praising O's latest business move.
A rep for Nutrisystem tells TMZ, Oprah's $43.2 million Weight Watchers investment helps everybody in the biz, saying, "We have a great amount of respect for Oprah and the spotlight she brings to the industry."
Nutrisystem is confident it'll keep its customers. The rep says, "It's a very large market that requires multiple solutions to meet consumers differing needs and lifestyles."
After O's investment, the WW stock shot up more than $7, making her a cool $45 million ... Nutrisystem saw a slight decline. Still ... no hard feelings.
Bob Harper thinks it's a stroke of genius on Weight Watchers' part to team up with Oprah, because she's a 10 on the relatability scale.
We got "The Biggest Loser" trainer leaving Brick CrossFit in West Hollywood Monday, after Weight Watchers' stock doubled on the heels of the announcement Oprah now owns 10% of the company's stock and will sit on its board.
Bob thinks Oprah's struggle with weight is actually a positive, because she has a deep connection with Weight Watchers' target audience.
Rob Kardashian not only looks like he's lost a lot of weight, there's a not-so-subtle message he seems to be telegraphing.

The drink on the table's interesting ... could be an ice tea, but maybe a red bull and vodka or a margarita. Door number 1 would be the wisest choice.
The TV host hobnobbed with celebs before the show. Saturday, she tweeted about a pre-Grammy feast, saying, "Tons of sushi and finishing off an entire bread pudding. #dinnerofchampions #whateverittakes."
