In Malaysia, food is more than just sustenance — it’s a way of life. 

From the creamy richness of teh tarik to the refreshing chill of ais kacang, sweet treats are an essential part of our daily indulgence.

But as delicious as they are, these sugary delights come with a cost, one that many of us overlook.

This is where Rex Au, better known as REXFIT, steps in. A 26-year-old fitness trainer turned TikTok sensation, Rex is on a mission to help Malaysians rethink their relationship with sugar and health.

“REXFIT” A name that says it all

For Rex, choosing his online persona wasn’t just a casual decision. It was a way to define his mission.

“My name is Rex, and I added ‘Fit’ because fitness isn’t just about muscles or looking ripped. It’s about being healthy,” he explained.

This mindset has guided Rex’s entire journey. But his story didn’t start on social media — it started with a realisation that health is about more than appearances.

Rex’s journey on TikTok began in October 2023, when he started posting videos for fun. But it didn’t take long for him to realise the potential of the platform.


“I started by sharing my lifestyle, which was about what I eat as a personal trainer and how I train. It felt like it was my responsibility to raise awareness about fitness and health,” he said.

As Rex explored new ways to engage with his audience, he discovered a niche market that would resonate deeply with Malaysians, which then led to the creation of his most popular series.

The Sugar Metre series

It was merely a video that featured a sugar meter, but little did Rex know that it would also change everything. 

Largely inspired by a US influencer, Rex decided to adapt the concept to Malaysia’s favourite drinks like teh tarik, Milo Dinosaur, and sirap bandung.

“Malaysians love sweet drinks. I’d ask my friends, ‘Sedap ke?’ and after one sip, I couldn’t drink it as it was too sweet!” he shared.

Rex then bought a sugar meter and tested it on several popular drinks, where the results shook him to the core.

“I wanted to show how much sugar we’re really consuming. After my first sugar metre video went viral, I realised that people actually found it interesting. So I kept going,” he shared.

This newfound focus on sugar awareness brought both praise and controversy. But for Rex, the reactions only reinforced the need for change.

His videos didn’t just open eyes — they also sparked debates. Some viewers were shocked, others became defensive, but the consensus was clear: Malaysians needed to rethink their sugar intake.

A personal struggle with sugar

Surprisingly, Rex’s journey with sugar isn’t just professional — it’s personal as well.

“There was a time where I was so stressed out that I drank Coke and ate cakes almost every day. In less than a week, I gained 2kg,” he admitted.

This wake-up call became the foundation of his approach to health and fitness.

“I realised how bad it was for my body — bloated face, pimples, you name it. So I promised myself that I’d change. I started a calorie-deficit diet and controlled my sugar cravings. 

“The first week was tough, especially when my friends were eating sweets in front of me.  But discipline is key,” he explained.

Now, Rex practices moderation. “I don’t cut sugar completely. Even rice and fruits have sugar. It’s about controlling intake, not eliminating it completely.”

Balancing sweet treats and culture

Rex knows that asking Malaysians to give up their beloved teh tarik, cendol or ais kacang is almost akin to asking them to stop breathing.

“These are heritage dishes passed down through generations. I wouldn’t say stop eating or drinking them. Just order kurang manis or enjoy them in moderation, maybe once a week,” he advised.

But changing habits isn’t always easy, as shown in a particular instance that still baffles Rex to this day.

“One time, my friend ordered a kurang manis drink. To me, it was already sweet. But then he added more sugar! I asked him why, and he said he couldn’t taste the sweetness. This mindset needs to change,” he said.

For Rex, sugar isn’t just about the taste alone, but also the risk it poses to one’s health.

“It’s not just about gaining weight. It affects your metabolism, insulin levels, and long-term health. Malaysians already face high rates of diabetes and it’s time to take this seriously.

“You don’t need to completely cut sugar. Balance is key. Think of your body as your responsibility because if you fall sick, who’s going to take care of you? Don’t let it come to that,” he urged.

Making fitness accessible

While Rex is aware that not everyone has the time or money for the gym, he still believes that fitness should be accessible to all.


“Bodyweight exercises are a great start. Resistance bands are affordable and effective for building muscle. You can also invest in dumbbells, kettlebells, or suspension trainers like TRX,” he said.

By keeping fitness simple and approachable, Rex hopes to inspire more Malaysians to take that first step.

When asked what dessert he’d save if sugar were banned in Malaysia, Rex had an unexpected answer: yoghurt.

“When I’m stressed, yoghurt is my go-to. Paired with fruits, it’s perfectly balanced. It’s not overly sweet and it keeps me grounded,” he said.

For Rex, fitness isn’t just about aesthetics — it’s about living a balanced, healthy life.


“If you want to make a change, plan your meals. Don’t go on extreme diets that stress you out. Balance is key. Stay active, jog a little, and most importantly, be consistent,” he advised.

Through his relatable approach and engaging content, Rex is redefining fitness for Malaysians. His journey proves that with discipline, awareness, and a little creativity, anyone can take steps toward a healthier lifestyle, one sugar meter reading at a time.
