The Evolution of Dietary Fears: From “Fat is Bad” to “Seed Oils Will Kill You”
May 29, 2024
Welcome back to Nacho Fitness Coach—where fitness is fun, food fads are funny, and bathroom soap is… optional? In this episode, Sara and Caleigh dive into a hilarious (and slightly horrifying) history of diet trends and nutrition fears that have swept the nation over the last few decades.
But first, a public service announcement: wash your hands, folks. Even if it means being called “vagina hands” by a bathroom attendant.
Now let’s get into the meat (or no-meat, depending on your diet era) of the episode.
🚨 Flashback: A Timeline of Dietary Fads and Fears
Fitness expert Sara breaks down a viral social media post shared by researcher Alan Aragon (shoutout to Mike Howard of @leanminded for the original content) chronicling the most iconic dietary fears from 1991 to today.
🗓️ Here's the breakdown:
1991: Fat is the enemy
- The “low-fat everything” era begins
- Fat-free cookies, fat-free dressings… and flavor-free food
- Food companies start pumping in sugar to make up for lost taste
2002: Enter the Carbs Villain Era
- Atkins Diet takes center stage—hello steak and goodbye bread
- "Carbs are bad" becomes the new fat fear
- Bars, books, and marketing galore
2005-2007: South Beach and Sugar Shifts
- Carbs are selectively bad now (depends on the city diet trend!)
- South Beach Diet gains popularity
- Sara dabbles in it post-athletic life, adjusting to a 40-hour desk job
2009: Weight Loss Pills & Water Pills
- The rise of over-the-counter fat burners like "Alli"
- Side effects? Uh, let’s just say keep a spare pair of pants handy
- Water pills and crash diets pre-wedding… not the best plan, Caleigh
2010: The “Skinny Bitch” Movement
- Meat becomes the next villain
- Real Housewives, skinny cocktails, and confusing nutrition messages
2011: Paleo Power
- “If a caveman didn’t eat it, neither should you”
- Goodbye grains, dairy, and legumes
- Hello CrossFit + Paleo culture (yes, even potatoes were off-limits… rude)
2013: Gluten is Plotting Against You
- Fear of gluten peaks
- Celiac disease is real, but mass gluten hysteria hits mainstream
2015: Fasting Frenzy
- Intermittent fasting becomes the hot trend
- “Breakfast is for chumps,” apparently
2016–2018: Keto Craze & Butter Obsession
- Keto hits hard with high-fat, low-carb love
- Bulletproof coffee becomes a thing (yes, that’s butter in your coffee)
- Whole30 rises: a “clean” eating plan or… a socially acceptable eating disorder?
2018–2020: Carnivore Comeback
- Veggies? Nope. Just meat.
- Carnivore diet goes full primal
- Everything circles back to protein
Present Day: The Seed Oil Scare
- Canola, soybean, and sunflower oils are now “Satan’s urine” (according to the internet)
- Fear of omega-6s and arachidonic acids (try saying that 3 times fast)
- Reality check: most restaurants use these oils… and we’re probably fine
🎙️ Real Talk with Sara & Caleigh
Throughout the episode, Sara shares her journey from trying South Beach to experimenting with CrossFit, while Caleigh pokes fun at the absurdity of all these food rules—especially when they start sounding like cults.
“One of my biggest fears—other than not being funny—is accidentally joining a cult.”
Relatable.
They also shout out researcher Alan Aragon, a great resource for evidence-based nutrition info, and his research review site that breaks down dense science into digestible bites for fitness pros.
💡 Key Takeaways
- Diet trends come and go—what’s vilified today might be praised tomorrow.
- Fat, carbs, meat, gluten, seed oils—everything’s been labeled “bad” at some point.
- Context matters. There’s no one-size-fits-all diet.
- Whole foods are great—but restriction isn’t always healthy.
- Question trendy fear-mongering before tossing out your potatoes or olive oil.
🥑 Final Thoughts
From fat to seed oils, the world of diet culture has thrown just about everything under the bus at one point. But maybe the real takeaway is this:
✨ Eat what makes you feel good. Be skeptical of extremes. And for the love of all things holy—wash your hands. ✨

What supplements should you actually take? In this fun episode of Nacho Fitness Coach, we unpack caffeine, collagen, creatine, probiotics, and whether melatonin is a sleep hack or just hype.
Muscle Milk vs. whey protein isolate—what’s the difference? We break down ingredients, benefits, and who should use which in this funny yet practical episode of Nacho Fitness Coach.
If you’ve ever bought a $50 tub of “miracle” greens powder, fallen for the latest detox tea, or wondered whether pink-labeled supplements for women are actually different (spoiler: they’re not), you’re not alone. In this episode of Nacho Fitness Coach, Caleigh (the self-proclaimed beginner who thinks Bulgarian split squats should be classified as cruel and unusual punishment) and Sara (the coach who actually knows what she’s doing) dive headfirst into the wild world of fitness scams —with plenty of laughs, tangents, and questionable jokes along the way. 🚨 Why Fitness Scams Are Everywhere The fitness industry is worth billions, which means there’s always someone ready to sell you a “shortcut.” Whether it’s a supplement that promises to torch fat, a crash diet that guarantees results in 30 days, or Instagram workouts that magically target belly fat, scams thrive because people want fast fixes. The reality? Sustainable health comes from the boring stuff : consistent movement, balanced nutrition, sleep, and stress management. But that doesn’t sell as well as “drop 30 pounds in 30 days.” 🤯 Popular Fitness Scams They Call Out Here are just a few of the fads and gimmicks discussed in the episode: Body Positivity (when twisted into an excuse) – Loving yourself is great, but ignoring your health isn’t. Raw Milk – Romanticized online, but not a magic bullet for health. Athletic Greens (AG1) – Expensive powders that are basically just multivitamins in smoothie form. Electrolyte Powders – Some (like Liquid IV or LMNT) are useful, but don’t believe the “double hydration” marketing hype. “For Women” Supplements – Same formula, pink label, higher price. Colostrum & Collagen Powders – Marketed as miracle youth potions. Spoiler: your regular protein powder works just fine. Probiotics – Helpful after antibiotics, but not the cure-all they’re marketed to be. Detox Teas & Cleanses – Your liver and kidneys already handle that job for free. Keto Desserts – Sorry, Jessica. That keto cupcake is still just a cupcake. 12-3-30 Workouts – Good exercise, but it’s not a “fat-burning secret.” Crash Diets (HCG, blood type diets, etc.) – Fast weight loss? Yes. Sustainable? Nope. And of course… everyone’s favorite scammy influencer, V Shred . 💡 The Bigger Problem: Normalized Fitness Lies The scariest part? Some scams are so normalized, we don’t even question them anymore. Marketing convinces us that we’re broken and need expensive fixes—when the truth is that health isn’t about extremes. What actually works: Consistency > hacks Real food > powders Movement you enjoy > gimmicky workouts Patience > promises of “30 pounds in 30 days” 🎧 Why You’ll Love This Episode Yes, you’ll learn how to spot scams. But you’ll also laugh (a lot). From butt-joke tangents to middle-schoolers discovering their teacher has a podcast, Caleigh and Sara remind us that fitness doesn’t have to be intimidating—or boring. If you’ve ever rolled your eyes at a detox tea commercial or wondered if collagen peptides are just expensive marketing, this one’s for you. ✅ Key Takeaway Don’t waste money chasing the latest fitness trend. Stick to the basics: move your body, eat balanced meals, get sleep, and stay consistent. Everything else is just expensive hype.
