What's The Actual Deal With Those Diet Teas?

Are they miracle weightloss drinks or just a pile of, well, crap?

Posting photos of fellow celebs Khloe Kardashian, Cardi B, Amber Rose and Iggy Azalea advertising products from diet companies Flat Tummy and Teami, you may recall actress Jameela Jamil  came out swinging earlier this week about diet and detox teas -- tweeting that she wants ‘all these celebrities to all shit their pants in public, the way the poor women who buy this nonsense upon their recommendation do.’

Yikes, right? Remember this?

Well, it didn't end there. She tweeted numerous messages about the products -- and the celebs who promote them:

And today she posted this hilarious -- but pointed -- video on Twitter. (Don't watch it if you're offended by, erm, toilet noises.)

So just what IS the deal with slimming teas and what do nutritionists say about them? Are they really as bad as Jameela would have us believe? Well, yes.

"I think the issue is they don't work," nutritionist Fiona Tuck told 10 daily.  "Some of them are highly caffeinated to give you energy, some of them are green tea based, some of them are herbal teas blended together, which are thought to relieve bloating and fluid retention and some of them have senna in them which are laxative based. They're the ones you should be careful of because it's teaching really unhealthy eating habits -- it's saying "go and eat what you like and then have this tea to cleanse your body". It's verging on laxative abuse."

The other thing with these teas is we don't know what is in them, we don't know where they come from, certain herbs you have to be careful with as they could interact with other medications or they could cause issues with the liver -- and if people are overdosing on diuretics then that could lead to nutritional deficiencies as well.

Jamil, the star of The Good Place and  @i_weigh activist also tweeted her fury about the misleading photos the celebs use.

And Fiona agrees. "When this all gets misleading is when the celebrities have gone on these really strict diets, they're working out, they have personal trainers and then post pictures of themselves in bikinis being paid millions of dollars to promote tea which isn't how they've lost the weight," she said.

"There are a lot of really gullible people out there and as a nutritionist, it frightens me. It's not giving people a healthy approach to food and more importantly a healthy body image. There are a lot of impressionable people out there who will do what they're told to do, and that concerns me.

As a nutritionist I don't recommend any diet fad -- if you are relying on a tea to lose weight then you're kidding yourself, You don't want to be relying on stimulants, on caffeine, or on laxatives to lose weight."

And if you DO want to lose weight, says Fiona, it's not about tea, you guys, sorry.

"It's about healthy eating -- it's 80 percent what you eat and 20 percent exercise, it's about changing your approach to eating and it's about health and wellbeing and cutting out processed food, upping the veggies and having a couple of pieces of fruit. It's not about a quick fix," Fiona said.

"Do it the boring way. We all want the quick fix -- but my advice is crowd out your plate with vegetables, have small amounts of whole grains, a little bit of protein, a little bit of good fat with every meal and get some exercise, cut back on processed food, cut back on refined carbohydrate and sugar... and you will lose weight."

Not a kooky diet tea in sight.
