Bulletproof Coffee Reality Check: Singapore Edition -- Part 2
Evidence-based protocols, local pricing, and what actually matters for brain health
Recap: What We Learned About Dave Asprey’s Butter Coffee Empire
In Part 1, we dissected Dave Asprey’s Bulletproof Coffee phenomenon—the 450-calorie morning beverage that promised IQ boosts, effortless weight loss, and cognitive enhancement without exercise or sleep.
Read: Which Part of Bulletproof Coffee is Snake Oil?
The fundamental problem:
Replacing breakfast with 450 calories of pure fat (zero protein, zero fiber, minimal micronutrients) creates nutritional deficiencies while consuming 2× the daily recommended saturated fat limit.
Now let’s look at the Singapore Bulletproof Coffee scene ← the actual costs, and what an evidence-based protocol looks like.
The Singapore Bulletproof Coffee Scene: Then and Now
Singapore’s Own Bulletproof Coffee (Before 2016)
Heap Seng Leong (an old-school cafe in Singapore) became internet-famous when people discovered they’d been serving Kopi Gu You (coffee with butter, “咖啡牛油”) since the 1970s — decades before Asprey “invented” it.
According to tour guides: “They’ve been making this Singaporean Bulletproof Coffee here since the 70s way before...” The drink is a traditional Singaporean concoction:
kopi (coffee)
a pat of butter melted on top
(optional) condensed milk may be added
The irony? Singapore had bulletproof coffee before it was cool. Traditional Kopi Gu You has been served since the 1930s in local cafes — brewed coffee with butter giving it a “smoother, thicker mouthfeel with a nutty finish” — as mentioned in Michelin’s Guide.
Health Food Places Start Selling (2016-2019)
Bulletproof Coffee hit Singapore hard around 2016-2017. The trend was everywhere:
Kitchen by Food Rebel (28 Stanley Street, Telok Ayer) became Singapore’s go-to spot, selling Bulletproof Coffee for S$6.50 per cup. The café specialized in organic, health-focused food and positioned itself as the CBD’s only organic café at the time.
Reviews praised their version: “Get a cup of their Bullet Proof Coffee to start your day right and stay fueled for hours.”
The Scene Today (2025-2026)
The dedicated Bulletproof Coffee craze has cooled significantly:
The Health Food market: crowded with competitors like Aloha Poke, Grain Traders, and numerous other wellness cafés in CBD.
The broader market: Bulletproof-style coffee is now available at various cafés, but it’s no longer the trendy buzzword it once was. You can still find it, but it’s integrated into regular menus rather than being a standalone phenomenon.
The DIY community: Many Singaporeans who were serious about the protocol now make it at home, realizing that buying the ingredients separately is far more cost-effective than S$6.50 per cup.
Online availability: Bulletproof branded products (coffee beans, Brain Octane MCT oil) are available through Amazon.sg, Shopee, and Lazada, but at significant premium prices ← There are numerous generic MCT oils that also work!
The keto community: With the rise of ketogenic diets in Singapore, MCT oil has become mainstream in health supplement shops, with multiple local and international brands available.

The Reality Check
Buying Bulletproof Coffee at café: S$6.50 per cup × 30 days = S$195/month
Making branded Bulletproof at home: S$135.90-163.20/month (saves 15-30%)
Making generic smart version at home: S$74.40-106.20/month (saves 52-62%)
Making budget version at home: S$45-66.60/month (saves 66-77%)
The bottom line: You’re paying 3-4× more for Bulletproof branding with zero functional difference. The C8 MCT oil from Sports Research or NOW Sports works identically to Brain Octane.
The Evidence-Based Singapore Protocol: 3 Versions
Now let’s create protocols that keep the legitimate science (MCT ketones, coffee benefits) while fixing Asprey’s mistakes (no protein, poor nutrition, IF contradiction).
Protocol 1: Maximum Brain Health (Recommended for Most People)
Morning Coffee: Drink with or after breakfast, add on 1 teaspoon to tablespoon of MCT oil in coffee
Actual Breakfast:
25-30g protein: Eggs, Greek yogurt, fish, chicken breast
Vegetables: 1-2 cups (spinach, tomatoes, mushrooms)
2 tablespoons extra virgin olive oil (drizzled on food)
Supplements: 2-2.5g Fish Oil (DHA+EPA) - Take with breakfast
Why this works:
Real food with complete nutrition
Protein prevents muscle loss
Fiber supports gut health
EVOO provides polyphenols for brain protection
Fish oil provides DHA for brain structure
Coffee provides caffeine + polyphenols
MCT oil optional for those who like ketones
Protocol 2: Keto/Time-Restricted Eating (For Those Actually Doing Keto)
Morning (8am): Make your own “Bulletproof Coffee”: 8-12 oz high-quality coffee, 1 tablespoon C8 or C8/C10 MCT oil, 1 teaspoon grass-fed butter (for flavor and tolerance), 1 scoop collagen peptides or whey protein isolate (20-25g protein), Blend until frothy. Why the protein addition is critical: If you’re skipping solid food until lunch, you MUST include protein to prevent muscle loss. Collagen or whey dissolves in hot coffee better than other proteins.
First meal (12-1pm): Must be protein and vegetable-rich, 30-40g protein minimum, 2-3 cups vegetables, Healthy fats (EVOO, avocado, nuts)
Supplements: 2-2.5g fish oil with first meal, EVOO throughout day (cooking, finishing)
Important: This is NOT intermittent fasting. You’re consuming 250-350 calories at 8am. Your eating window starts at 8am, not noon. Don’t confuse the two.
Who this works for:
People already on ketogenic diet
Those with true time constraints in morning
Individuals who respond well to fasting protocols
NOT for people expecting this to replace nutrients
Protocol 3: Traditional Singaporean Budget Version (This is What I Do)
Morning: home-brewed coffee or store-bought with small amount butter/MCT
First Meal: Eggs, Protein, (optional) Avocado
Supplements: 2 tablespoons EVOO (cooking or finishing), 2-2.5g fish oil supplement
Why this works:
Much cheaper than Western keto approach
Still gets you fish oil and EVOO benefits
Coffee from kopitiam: S$1.20-2.00
The Non-Negotiables: More Important Than Any Coffee Protocol
Here’s the uncomfortable truth Asprey downplayed: No amount of butter coffee compensates for poor fundamentals.
Priority List (In Order of Impact on Brain Health)
1. Sleep: 7-9 Hours Nightly
Most powerful intervention for cognitive health
No biohack replaces this
Poor sleep eliminates benefits of everything else
Singapore challenge: Workaholic culture, long hours, late nights
Fix this FIRST before fancy coffee
2. Exercise: 150 Minutes Weekly Minimum
Single most powerful intervention for brain health
Reduces dementia risk more than any dietary supplement
Promotes BDNF (brain-derived neurotrophic factor)
Must include: Resistance training 2-3×/week + cardio
No oil or supplement replaces this
3. Protein: 25-30g Per Meal
Essential for muscle maintenance
Supports neurotransmitter production
Critical during weight loss or fasting
Singapore has excellent protein sources: Chicken rice, fish, eggs, tofu
4. Vegetables: Multiple Servings Daily
Fiber for gut health (which affects brain)
Micronutrients, polyphenols
Singapore advantage: Incredible variety, affordable
Eat the rainbow
5. Stress Management: Daily Practice
Chronic stress destroys brain health
Singapore challenge: High-pressure work environment
Solutions: Exercise, nature time, meditation, hobbies, social connection
6. Hydration: 8+ Glasses Water Daily
Coffee is primarily hydrating in moderation, despite caffeine being a mild diuretic.
Still, you have to drink your water daily.
If you’re not doing these six things consistently, fancy coffee won’t save you. Fix your fundamentals first, then optimize with oils and supplements.
Why EVOO and Fish Oil Beat Bulletproof Coffee
Let’s be completely honest about the research hierarchy:
Extra Virgin Olive Oil:
✅ Large population study: 28% reduced dementia mortality risk
✅ Proven BBB enhancement in MCI patients
✅ Cardiovascular PROTECTIVE (doesn’t raise LDL)
✅ Can use forever without health concerns
✅ Cost-effective
Fish Oil (DHA+EPA):
✅ Meta-analysis of 103,000+ people: 20% reduced cognitive decline
✅ Structural component of brain cells
✅ Cardiovascular PROTECTIVE (lowers triglycerides)
✅ Evidence across dozens of studies
✅ Well-tolerated long-term
Bulletproof Coffee (Butter + MCT):
⚠️ Based primarily on one person’s anecdotal experience
⚠️ No large population studies
⚠️ Cardiovascular CONCERNING (24g saturated fat daily)
⚠️ Nutritionally incomplete (no protein, fiber, micronutrients)
⚠️ Requires monitoring
✅ MCT ketone production is real (only validated part)
If you only have S$100/month for brain health:
Spend S$70 on EVOO + fish oil (proven, safe)
Spend S$30 on good coffee (any brand)
Skip the butter and overpriced “Brain Octane”
Conclusion: Best Way To Implement This Locally
The best version of Bulletproof Coffee is: good coffee + optional MCT oil + collagen protein, consumed as part of a complete, evidence-based nutrition and lifestyle protocol that includes actual food, exercise, and sleep.
You don’t need to pay S$65 for Brain Octane or S$6.50 for café butter coffee. Generic C8 MCT oil from Shopee works the same, and your hawker uncles have been making butter coffee since before Dave Asprey was born.
The final takeaway: Use the tools (MCT oil, caffeine), skip the snake oil (fear-mongering, overpriced branding), and don’t forget the fundamentals (sleep, exercise, fish oil, vegetables).
