People are obsessed with how old internet personalities are. It’s a thing. When it comes to the controversial TikTok creator known as Kadie Karen Diekmeyer, the query that vegan teacher age hits search engines thousands of times a month. Why? Because she looks lean, she’s high-energy, and her confrontational style makes people wonder if her lifestyle is actually "working" for her—or if she’s just an anomaly.
She's 61.
Kadie Karen Diekmeyer was born on September 24, 1964.
That might surprise you. Or maybe it doesn't. Depending on which side of the vegan debate you land on, you either think she looks incredible for a woman in her sixties or you use her appearance as a talking point against plant-based diets. It’s wild how much a single number can fuel a massive online firestorm.
The Viral Mystery of That Vegan Teacher Age
The fascination with her age isn't just about curiosity. It's weaponized.
On platforms like TikTok and YouTube, creators often zoom in on her face, analyzing her skin texture or hair thickness to "prove" that veganism is either a fountain of youth or a recipe for disaster. It’s pretty reductive. Honestly, most of these "analyses" ignore basic genetics, sun exposure, and the sheer stress of being one of the most hated people on the internet.
Before she was a digital lightning rod, Diekmeyer was a nurse. She also worked as an educator. This background gave her a specific kind of authority—or at least the confidence to speak like an authority—when she started her "Eating Animals is Wrong" campaign. By the time she blew up on TikTok in 2020, she was already in her mid-50s, a demographic that usually doesn't dominate the "For You" page.
Her age set her apart. She wasn't some Gen Z influencer filming "What I Eat in a Day" videos with aesthetic lighting. She was a middle-aged woman with a ukulele, singing songs that called out Gordon Ramsay and Disney. That juxtaposition is exactly why she went viral. You don't expect a 61-year-old former nurse to be banned from TikTok for multiple community guideline violations.
Life Before the Ukulele
Kadie wasn't always "That Vegan Teacher."
She lived a relatively quiet life in Montreal, Quebec. For decades, she worked in the healthcare system, which she frequently references when people question her understanding of biology. She didn't even go vegan until later in life—around 2016. That means she spent roughly 50 years of her life as a meat-eater.

This is a crucial detail that people looking up that vegan teacher age often miss.
If you're looking at her physical health as a "case study" for veganism, you're looking at a body that was built on an omnivorous diet for half a century. Biology is slow. The bones, the collagen structure, the foundational health she has now was largely established long before she ever touched a head of kale.
Why the Internet Can't Stop Talking About Her
It's the aggression. That's the short answer.
Most vegan creators focus on recipes or animal welfare in a way that’s, well, digestible. Diekmeyer took a different route. She went for the jugular. She targeted big creators like MrBeast and TommyInnit, often using her age as a "motherly" or "teacher-like" shield to deliver harsh criticisms.
- She used her platform to tell kids their parents were "murderers."
- She compared animal agriculture to the Holocaust—a move that rightfully sparked massive outrage and accusations of anti-Semitism.
- She leaned into the "Teacher" persona to "grade" other people's lives.
When you act that way, people look for weaknesses. They look for wrinkles. They look for signs of fatigue. They search for that vegan teacher age because they want to find a "gotcha" moment. If she's 61 and looks 61, some claim she's "failing." If she looks younger, her fans claim it's the power of plants. In reality, she just looks like a woman in her sixties who lives a very active, albeit controversial, life.
Physical Health and the 60-Plus Vegan Lifestyle
Let’s talk about the science for a second, because that’s usually where these searches lead. Can you be a healthy 61-year-old vegan?
Absolutely.
The Academy of Nutrition and Dietetics has stated for years that appropriately planned vegan diets are healthful and nutritionally adequate for all stages of the life cycle. But "appropriately planned" is the heavy lifter in that sentence. For someone in their sixties, certain things become non-negotiable:
- B12 Supplementation: You can't get this from plants. Period.
- Protein Density: Sarcopenia (muscle loss) is a real threat as we age.
- Bone Density: Calcium and Vitamin D are vital, especially for post-menopausal women.
When people scrutinize her, they are often looking for signs of these deficiencies. It's a weird form of digital voyeurism. We've become a society that tries to diagnose people through a smartphone screen.

Honestly, the obsession with her age says more about our society’s ageism and our polarized views on diet than it does about her. We want her to be a caricature. We want her to be either a "vegan goddess" or a "cautionary tale." She’s neither. She’s a 61-year-old woman with a webcam and a very loud opinion.
The Impact of Social Media on Aging Creators
The internet is notoriously cruel to women over 40.
For Diekmeyer, this cruelty is amplified by her own behavior. Because she attacks others, the internet feels justified in attacking her appearance. It creates a toxic feedback loop. She posts a video, people comment on her "sunken eyes" or "grey skin," she responds with a song about how "meat-eaters are dying," and the cycle repeats.
It’s exhausting just watching it.
But from a brand perspective, the "That Vegan Teacher" persona is a masterclass in engagement. Negative engagement is still engagement. By leaning into the controversy, she ensures that people keep typing her name into Google. Every time someone asks "how old is that vegan teacher," her SEO value goes up. She has turned her own aging process into a marketing tool.
The Controversy Timeline: Beyond the Birth Date
To understand why her age matters, you have to look at the sheer volume of "wars" she has started.
- The TommyInnit Incident: She told a then-minor that he needed to go vegan, which many felt was predatory and weird.
- The Gordon Ramsay Response: Ramsay famously ate a burger in front of one of her videos, which became one of the most-liked Tiktoks of all time.
- The Permanent Ban: In early 2021, TikTok finally pulled the plug on her main account. She had millions of followers. She just moved to YouTube and keep going.
Throughout all of this, her age was used as a weapon. Critics called her "grandma" as an insult. She reclaimed it, calling herself "the world's teacher." It’s a fascinating study in power dynamics. Usually, in the influencer world, youth is power. Here, she uses her seniority to claim a moral high ground that her critics find infuriating.
Does Her Age Actually Validate Her Message?
This is the $10,000 question.
If she were 22, people would say, "Wait until you're older, then you'll see." Since she's 61, she’s already "older." She is living the long-term results of her choices. But again, we have to remember the 50-year "meat-eating" head start.

Veganism in your 50s and 60s is mostly about maintenance. It's about reducing inflammation, managing cholesterol, and staying active. Diekmeyer is undeniably active. She films, she edits, she cycles, she sings. Whether you love her or hate her—and most people lean toward the latter—she has a level of stamina that many 60-year-olds envy.
Is that the veganism? Is it just her personality? Is it spite? Spite is a hell of a drug. It can keep you going longer than a green smoothie ever could.
What You Should Actually Take Away
Searching for that vegan teacher age usually stems from a desire to see if her lifestyle is "sustainable." But one person is never a statistically significant sample size.
If you're looking at her and thinking about going vegan, don't do it because of her. And don't avoid it because of her. Look at the actual peer-reviewed data. Look at the Blue Zones, where people live to 100 on mostly plant-based diets. Look at the cardiovascular benefits of reducing red meat intake.
Don't look at a TikToker with a ukulele.
Practical Steps for Evaluating Health Claims Online:
- Check the Background: Did the person spend most of their life on a different diet? In Kadie's case, yes.
- Look for Supplements: Is the "natural" diet actually being supported by pills? (It should be, if it's vegan).
- Ignore the "Glow": Lighting, filters, and camera quality change everything.
- Verify Birthdates: Use reputable databases like Famous Birthdays or official public records, not just "vibe checks" from comments sections.
Kadie Karen Diekmeyer is 61. She was born in 1964. She’s a Virgo. She’s a former nurse. She’s a vegan. She’s a provocateur.
Knowing her age doesn't actually solve the mystery of whether she's "right" or "wrong." It just gives you a bit more context on the woman behind the screen. Whether she's a "menace" or a "hero" is entirely up to your own moral compass, but at least now you have the facts straight.
If you're genuinely interested in how aging and diet intersect, focus on your own blood work and nutritional density. That’s way more productive than arguing with a 61-year-old on the internet. Trust me.
Next Steps for the Curious:
- Verify her nursing credentials through the Order of Nurses of Quebec if you're skeptical of her medical claims.
- Research B12 and aging if you're over 50 and considering a plant-based shift.
- Analyze the "Blue Zones" study by Dan Buettner to see how actual 100-year-olds eat, rather than relying on social media personalities.
- Audit your social media feed. If a creator makes you feel angry or anxious, the "unfollow" button is a powerful tool for your own mental health.
Ultimately, Kadie Karen Diekmeyer has achieved what every creator wants: she has made herself a permanent fixture in our search bars. Whether it’s through her songs or her bans, she’s staying relevant long past the "expiration date" the internet usually sets for women. And at 61, she doesn't seem to be slowing down one bit.
