Previously on The Biggest Loser we witnessed the first weigh-in of the season, along with the revamped elimination process. After falling below the yellow line in the losing team, Sarah, Matt and Amy faced The Arena, an elimination challenge.

Matt put in his first strong performance for the season and was safe after the first round on the spinbikes, then Sarah failed to hold out against a deceptively strong Amy in the marathon portion of the challenge. It remains to be seen what future challenges will be faced in The Arena, but so far… do we like it? Sound off in the comments below!

Meanwhile, on with the show. Tonight on The Biggest Loser… More breakdowns and breakthroughs, especially with the Blue Team who have now lost two contestants.

Also, bestselling cookbook lady Sarah Wilson is in the house/kitchen thing for some more learning about food and diet stuff. She has no formal or informal but well-regarded qualifications in any relevant field and has expressed unfounded concerns regarding the safety and efficacy of vaccines. You should not listen to her.

First up, Brett’s not at training for Team Blue. He was feeling sick yesterday and today so he’s been quarantined away from the rest of the contesants. Poor bugger!

Shannan congratulates Simmo on being Biggest Loser of the Week, but also asks them how they feel about Sarah having been sent home. Anna in particular is bummed because she liked training with Sarah. Sarah would be at home wishing she was still there, so they’ve all got to fight hard to stay in the game. Shannan says that’s why he had to speak the way he did to Matt yesterday, he does apologise for it though.

Shannan wants them to rip back into training, he can’t afford to lose another contestant already.

Today… time to box! Matt’s stomach drops, but he realises that’s the old Matt, time to face his fears.

Libby’s perky as ever! Her team is just walking into the gym so she gets them to jog up to her instead, no walking in her gym.

50kg at the weigh-in is a great result so she’s really happy with her team. And Sophia’s really enjoying the first exercise, punching the air, then feeling good during the squats and lifts. “I’m fat, but flexible!” Oh my!

Sophia says the hardest thing about being overweight is always thinking other people are making a joke of them. So now she tends to make a joke of herself and plays the fat, jolly girl. She gets in first, with a constant coverup that she says is killing her inside.

Not anymore though, she’s chuffed with her result at the weigh-in. And she should be, she smashed it!

Sophia and the other girls are doing semi-burpees without the jump up but Libby says she thinks Sophia’s ready to push further and add the jump, which she’s managing as well. Josh is thrilled to see Sophia pushing hard as it’s a good motivator for him and the rest of the team.

“What do we sayyy?” “No one remembers who came second!”

Shannan’s got his team doing some boxing and they’re dripping wet and puffed but they’re all having fun. Except Matt.

First drill is just learning to defend. Just gloves up, take the body jabs. He got pushed around in school, so it’s difficult for him. But Shannan’s willing to take the time to get him through it.

Matt turns away at one point, freaking out. Shannan asks him why it’s so hard for him and Matt doesn’t want to talk about it. Shannan does though! Let’s get real, no secrets, Matt promised 100% this week.

Matt got bashed over many years in high school, so feeling the punches brought it all back for him. This is part of his transformation, Shannan says, trust him. Matt apologises for crying, but Shannan says don’t apologise, he’d be disappointed if Matt wanted to cry but suppressed it for fear of being embarassed. It’s all about being honest and open with everyone now. He’s 37, but he’s still got the 15 or 16 year old in his head. Shannan says it won’t always be there nagging at him, he can move past it. It’s in the past, so you can’t deny it, but you don’t have to let something from 25 years ago hold you back. He wants to give Matt the tools to look after himself physically and mentally.

Matt gets back into the training, sparring a little with Shannan and getting a smile back on his face. Shannan’s really pleased with his progress by the end.

And now… Dr Andrew Rochford! As seen on TV!

Apparently the other day they had a dexascan? Lynton says they had one. It’s like an x-ray, but for fat!

It shows different colours for different densities. White for bones, blue is muscle, lesser fat is green, bigger fats are yellow. BMI isn’t so useful, since it doesn’t discriminate between muscle, bone or fat.

Dr Andrew says the way he approaches it is that they’re not “fat”, just that they have fat. Not quite how it works, but okay!

Anna’s body fat percentage is 37.6%. Which equates to 43.6kg of fat! Anna’s shocked, but also kind of knew it. She loves kids, doesn’t want to be a godmother yet again, she wants to be a Mum herself. She’s also become a foster Mum, so she wants to keep doing that as a healthier and fitter version of herself.

Anna’s scan shows a lot of the greeny yellow fats. Icky!

Jake’s body fat percentage is 25.6%, 30.8kg. In “Fat Mass Index” he’s just “Excess Fat”, not even one of the Obese gradings.

Andrew says that Jake’s Type 1 diabetes is something he can’t really do anything about, and it affects his health in a number of ways. Amy says Jake’s a great guy, so seeing him struggle with his diabetes is heartbreaking.

Having Type 1 diabetes means he has too much blood sugar, leading to damaged blood vessels in your heart, eyes, everything. Excess fat can push you into Type 2 diabetes, so Jake can tell them how bad it can get for the rest of them.

Lisa-Faye (not a real name) is told that excess body fat can lead to a higher risk of many female-specific cancers, which worries her as her Dad died five years ago of cancer.

Her body fat percentage is 34%, 34.4kg. She says it’s her three year old son times four in fat!

Luke’s next. He’s 35 and would like to play Over-35s Australian Rules Football. He’s the sales and sponsorship manager of the Cranbourne Turf Club. So he gets to wine and dine various sponsors, which is a great perk but he has fatty liver disease already.

Good thing he’s not one of the horses that go round at Cranbourne or they’d shoot him in the head!

Luke’s body fat percentage is 30.2%, 36.8kg.

The scan of his body looks pretty bad, with a lot of the fat around his midriff. Men in particular have to worry about this because it increases the risk of high blood pressure, impaired liver function.

Sophia’s 35.2% fat, 36.3kg. A lot of extra weight, Andrew says. “Yeah, thanks!”

Steph’s fat weighs 37.6kg. Steph is thoroughly disgusted by her scan. Andrew says all the fat produces oestrogen, which tricks the body into thinking it’s on the pill.

Well, no, the pill tricks your body with oestrogen… Oh nevermind.

Matt’s at the very lower end of the obese bracket. He’s not thrilled either.

Nikki’s body fat percentage is 32.4%, 24.8kg. She’s short and the lightest contestant so that’s a LOT.

Lynton’s 35% body fat, 42kg. Andrew’s giving Lynton 42kg to carry to give him an idea of how much weight that is. It’s about 42kg, which is rather heavy. Surprise!

Simmo’s the first into Obese Class 2. Simmo hadn’t really considered himself to be obese before.

Josh’s body fat percentage is 36.1%, 52.1kg! Obese Class 3. He knows it’s only a matter of when he’ll have a heart attack, not if he will.

So with that cheery news, off to the kitchen to learn about where all that fat came from!

Fiona’s in the kitchen again, hooray! Fiona introduces her new guest, Sarah Wilson. Journalist and writer of bestselling book “I Quit Sugar”.

DISCLAIMER: What follows is Sarah Wilson’s OPINION. Sarah Wilson has no scientific or medical qualifications AT ALL. CONSULT QUALIFIED PROFESSIONALS BEFORE BELIEVING OR ALTERING YOUR DIET ACCORDING TO THE FOLLOWING.

She quit sugar seven years ago after learning she has an autoimmune disease. She looked like a healthy eater, having honey and muesli with dates and banana, but she was having about 30 teaspoons of sugar a day.

So Sarah went to a shed in the forest for a year and a half and developed recipes and looked into the science of addiction and why sugar has such a hold on people. At the other end her productivity had lifted and her autoimmune disease had started to mend itself. She’s healthier now than she was fifteen years ago, she says.

Sugar isn’t all the same, Sarah tells everyone. Table sugar, for instance, is glucose and fructose. Glucose is “great stuff”, it’s in everything we eat. It’s fructose that’s the problem, it goes to the liver and then goes into your fat stores, leading to insulin and diabetes related issues.

Fiona says that fructose makes her think of fruit, is she saying fruit is bad?! Fruit’s not a problem, Sarah says. It’s the sugar we add to food.

First up, recommended guidelines for how much sugar you should have each day. Men, how many teaspoons a day? 9! Women, how many teaspoons a day? 6! Childrens? 3! These are all “added sugar” per day, not total intake by the way.

How much sugar in a granola bar? 6 teaspoons of sugar apparently. Everyone assumes granola and muesli bars are good for you.

Banana bread? Must be healthy, got bananas in it! 7 teaspoons of sugar, apparently. Nikki’s horrified, she always has slices of banana bread when she goes to cafes.

“Sugar actually has no off switch in the brain. Other foods we eat have a hormonal off switch in the brain that says, I’ve had enough. So many of us who are sugar addicts actually don’t even know what appetite feels like.”

Next up, apple juice. Mmmm, apple juice. It has 6 teaspoons of sugar in it, apparently. Everyone is horrified. IT’S JUST APPLE JUICE, IT’S FINE.

Low fat yoghurt has 3-4 teaspoons of added sugar. They remove the fat and add sugar, apparently. Which makes the low fat version more fattening when we eat it.

REMINDER: Sarah Wilson has no qualifications in the scientific or medical fields. NONE.

Anyway, on to a recipe. That’s a bit less controversial. It’s a food challenge day! It’s an homage to a Friday night treat her Dad used to bring home, the Wagon Wheel. They’re cooking her Gut-Loving Wheelies.

Fructose-free, obviously. Biscuit base is gluten free, buckwheat flour and butter and rice malt syrup as a sweetener. Chia raspberry jam is the next layer. A form of marshmallow is next, full of collagen which is “great for the gut” apparently. And a homemade layer of chocolate on top.

And now everyone can have a taste. Genius, you have no idea how many calories are in the bloody things!

It takes one hour and forty five minutes to create the Wheelies and they’ll be doing the cooking in a relay. Each team member will only be in the kitchen fifteen minutes at a time. Blue are missing a member (sick Brett!) plus the gone Jenny, so they’ll have to have three members cook twice. When the time is up the taste testing will be decided by Fiona and Sarah. The winning team will have exclusive use of the gym equipment in the house for the whole week.

Anna’s first cook for Team Blue, Steph for Team Orange.

Anna manages to get some of the ingredient picking-up done, but she’s feeling a bit faint and doesn’t really get enough done. Matt’s next and he’ll have to catch up. He’s never cooked with chia seeds before so his jam may not be great.

Chia seeds absorb up to 7 times their weight in water, which gets the gummy jammy feel.

Lisa-Faye (not a real name) is pressured into pulling the team’s biscuit base out of the oven and into the freezer, but Sarah checks on it later and confirms it wasn’t done. Oops!

Simmo and Lynton are trying to help by reading out the instructions, which Lynton thinks is helping but is just flustering Amy.

Luke’s hoping to do the whole marshmallow bit for his team… but in the end he just does the dishes for his team, rather than mess anything up. Hah!

Josh is making chocolate out of weird ingredients. The recipes are on the official site if you want them. Or you could just be a normal person and buy a proper Wagon Wheel. I won’t judge you.

Lynton’s got the marshmallow in their whisking machine… but it’s gone wrong! It looks disgusting and they’ll have to try doing the whole thing again. Luckily Amy tags back in and takes over the recreation. Hopefully it goes better next time.

Matt’s got the last leg, maybe? He’s pouring the chocolate over the pan while it’s still hot and they’re putting it into the freezer to try and hurry things along.

The end result is kind of a mess, very thin coating of chocolate with lots of it having poured off the sides.

Simmo’s carving for Team Blue, choosing larger slices than Team Orange. It also looks a bit messier in general than Team Orange. Blue’s remaining hopeful, however!

When Fiona and Sarah look at the size of the slices they both remark it’s a bit big, but Simmo tries to spin it by saying it’s a shared dish, for partners, he’s looking for love. Everyone gets a good laugh out of that.

The marshmallow is nice and Fiona likes the thickness of the raspberry layer, and the ooziness!

Team Orange’s slice cuts a lot more neatly and cleanly. The marshmallow is light and fluffy and the chocolate is much better than Blue’s. The biscuit’s a little underdone though.

Blue’s ratios were way out of whack and the portion sizing was way too big, Orange had an undercooked base but everything else was great. Team Orange take away a kitchen win, getting exclusive use of the gym equipment for the week.

Tomorrow night! Kuring-gai National Park is the setting for another epic challenge. Teamwork will be crucial and it sounds like another elimination will haunt the losers. Hope Blue can rise to the challenge, or they’ll be down yet another contestant while Orange remains intact!
