Former Hollyoaks star Davinia Taylor has become an unexpected voice in the wellness space, and her message is turning heads.
After losing three and a half stone, she’s not crediting calorie counting or endless cardio.
Instead, she’s pointing fingers at something lurking in nearly everyone’s kitchen: vegetable oil.
Her transformation wasn’t just about weight loss—it was about reducing inflammation that had her knees swollen and her wedding ring unable to fit.

Inflammation Was the Hidden Culprit
Taylor’s weight struggle wasn’t simply about carrying excess fat. Inflammation had taken over her body in ways she hadn’t fully recognized.
I wasn’t just like carrying excess fat, it was inflammation. You can see my knees are inflamed, I couldn’t fit my wedding ring on.
When she consulted doctors, the advice was predictable: follow a calorie-controlled diet. But Taylor suspected something deeper was happening.
If you want something simple that actually works, this is one of the most effective tools I’ve used to build strength, conditioning, and endurance without needing a full gym setup.
- Full-body training with one weight using swings, squats, and presses
- Solid cast iron build that feels stable and lasts for years
- Comfortable grip that makes high-rep workouts easier to handle
Your body is in distress. My theory is we are being poisoned by little tiny ingredients that have trickled down into our food chain and we’re unaware of.
The Vegetable Oil Revelation
While sugar gets most of the blame in health conversations, Taylor discovered her biggest enemy was marketed as healthy.
Vegetable oils—particularly sunflower and rapeseed oil—are ubiquitous in processed foods and restaurant kitchens. They’re labeled heart-healthy and promoted as better alternatives to saturated fats.
Taylor disagrees vehemently.
When I removed this ingredient from my diet as much as I possibly could, it was phenomenal. Brain fog went, cravings went.
She now tracks her glucose levels with a continuous monitor and avoids the constant spikes that trigger brain fog and energy crashes throughout the day.
Why She Calls Vegetable Oil a Detergent
Taylor’s comparison sounds shocking, but she’s drawing from personal observation and research into how these oils are processed.
Vegetable oil is a total fabrication. It’s totally false. There’s no such thing as vegetable oil—vegetables don’t have oil.
She points to household cleaning products that contain vegetable oil as their primary ingredient. One example: a popular stain remover called “the pink stuff” that she uses for her four rugby-playing sons.

First ingredient in there is vegetable oil. It’s a detergent. It literally strips the lining of your gut of mucus, and in that mucus is where your hormone receptors are to tell your brain you’re satisfied.
According to Taylor, this stripping action disrupts satiety signals, leaving people perpetually hungry and craving more food.
What She Uses Instead
Taylor has completely overhauled her cooking fats. Her kitchen now contains:
- Butter for most cooking needs
- Avocado oil for high-heat cooking
- Lard as another high-heat option
She avoids olive oil for high-temperature cooking and has eliminated rapeseed and sunflower oils entirely.
The Addiction Trap of Processed Foods
Taylor describes processed snacks as biochemically engineered to override natural fullness cues. Take Pringles, for example.
They advertise it: once you pop you can’t stop. And it’s true. You have that, you’ve got a subconscious message going to your brain saying let’s have another.
Combine vegetable oil with salt and sugar, and you’ve created what Taylor calls “the gravy train”—an unstoppable cycle of cravings and consumption.
This combination hijacks hormone signaling, making moderation nearly impossible for many people.

Why “Everything in Moderation” Doesn’t Work
Taylor pushes back against conventional wisdom that moderation is key.
I can’t moderate something that’s highly addictive and it’s like sending my hormones—I’m seeking more and more.
She describes cravings as productivity killers that dominate mental space, creating constant distraction and the urge to snack.
The DNA Test That Changed Everything
Taylor’s journey into nutrition science began after her mother was diagnosed with breast cancer. Following genetic testing, she discovered vulnerabilities she’d inherited.
Most significantly, she learned she has a genetic variation that impairs her liver’s ability to detoxify effectively. She doesn’t produce adequate amounts of glutathione, a master antioxidant crucial for processing toxins.
I wanted to know—I have no trauma in my life—what triggered that. I started looking at my liver’s capability to detox, and I don’t detox well at all.
This genetic insight explained her struggles with alcohol. She’s been sober for 14 years, but understanding the biological mechanism behind her “ferocious hangovers” and fearfulness gave her clarity.
It’s not my fault, it’s not willpower, it’s my actual genetics that are doing this to me. And it gave me some sort of ease.
Brain Fog, Energy, and Food Quality
Beyond weight loss, Taylor emphasizes how dietary changes transformed her mental clarity and energy levels.

Constant glucose spikes—tracked through her continuous monitor—correlate directly with brain fog episodes. Eliminating vegetable oils and managing blood sugar has virtually eliminated these crashes.
I hate feeling sluggish, I hate feeling lethargic, and that’s exactly what our diet’s doing to us.
Sharing Underground Information
Taylor acknowledges she’s not a doctor, but she’s become passionate about sharing research that remains relatively unknown in mainstream health conversations.
It’s quite underground, you know. I just wanted to put the information out there so people can make their own decisions.
Her book, It’s Not a Diet, became a Sunday Times bestseller, suggesting her message resonates with people frustrated by conventional weight-loss advice.
Taylor’s approach focuses on identifying and eliminating ingredients that trigger inflammation and hormonal disruption, rather than simply restricting calories. For her, sustainable health came from understanding her unique genetic makeup and removing foods her body couldn’t properly process.
Whether vegetable oils deserve their health halo remains debated in nutrition science, but Taylor’s personal transformation—and her passionate advocacy—has certainly sparked conversation about what truly belongs on our plates.
