Effects of Coffee on the Carnivore Diet: A Complete Guide to Strategic Caffeine Use
Coffee is the diesel that drives modern society, with billions of cups consumed every day. Coffee‘s rich legacy across cultures and role as a social lubricant for events has embedded it into the very fabric of everyday life. As food blogger Mark Schatzker quips, “Is it a coincidence that a society that consumes hundreds of billions of cups of caffeine a year is also a society that works hard, drives fast, and seems to exist in a continual state of tension and anxiety?”
Yet a new nutritional movement in recent years – the carnivore diet – calls into question coffee‘s place at the breakfast table. With followers restricting intake solely to meat and animal products, does coffee undermine or support wellness goals on such an extreme eating template? This insider’s guide provides definitive answers on strategic coffee use within a carnivore lifestyle.
Coffee by the Numbers: Global Consumption Statistics
Before analyzing coffee‘s biological impact, let’s visualize its unmatched popularity across the globe:
-
As functional medicine doctor Shawn Baker describes, “There‘s about two billion – 2 billion with a b – cups of coffee consumed around the world every single day." That’s over half a billion cups per hour!
-
Americans alone consume 400 million cups of coffee per day, equivalent to 146 billion cups per year (9). Compare that to the United State‘s 20 million vegans and vegetarians combined (10).
-
The average American worker spends $1,100 per year on coffee (11). That’s a hefty grocery bill dedicated to a single beverage.
-
Finland tops all countries at consuming 12kg of coffee per capita annually, with Canada and Sweden not far behind (12).
-
Brazil once financed their entire Olympic team‘s expenses by harvesting and selling coffee all along the route to the 1932 Los Angeles games (13). Those must have been some exceptional beans!
With coffee firmly ingrained in various cultures and economies alike, could it really be problematic for one’s health? Let’s analyze the compound itself.
Proposed Benefits of Coffee
While opinion remains split, several advantages have been associated with coffee consumption:
Enhanced Exercise & Cognitive Performance
The metabolic boost coffee provides can enhance exercise, concentration, and work effectiveness. These benefits stem primarily from caffeine – coffee’s widely-researched psychoactive constituent.
Caffeine ingestion directly stimulates the central nervous system, triggering elevated heart rate, heightened blood pressure, and the release fat stores for energy usage (14). Performance-wise, caffeine reduces perceived physical exertion during demanding activities. One research review found that a low-moderate dose (3-6mg/kg) improved exercise time to exhaustion by 12-16% across multiple studies (15).
Mentally, caffeine blocks inhibitory neurotransmitters like adenosine, while spurring excitatory brain chemicals dopamine and glutamate (16). The outcome is increased neuronal firing, elevating mood, reaction times, memory, and focus. Unsurprisingly, one study discovered that caffeine intentionally consumed before playing video games enhanced player performance and immersion (17).
Antioxidants & Disease Prevention
In addition to caffeine’s impact, coffee beans contain antioxidant plant compounds like chlorogenic acid and quinine. Researchers correlate higher dietary antioxidant intake with reduced risk of type 2 diabetes, heart disease, stroke, Alzheimer’s, Parkinson‘s, and liver cirrhosis (18). One analysis of over 200,000 participants associated each daily cup of coffee with a 7% lower risk of type 2 diabetes (19).
Coffee also provides modest levels of essential nutrients like riboflavin (Vitamin B2), niacin (B3), potassium, and magnesium (20). Yet coffee alone cannot offset poor nutrition elsewhere in one’s diet. As Dr. Baker cautions, “I don‘t care how much coffee you drink, it‘s not going to compensate for…sitting on the couch, doughnuts, bon bons, sodas.” The benefits of isolated compounds pale against sustained junk food consumption.
Potential Downsides of Coffee
Despite the allure of enhanced athleticism and productivity that coffee provides, it may undermine goals for those pursuing fat-adaptation and heightened wellness.
Antinutrients: Lectins & Phytates
Like all plant foods, coffee beans contain antinutrients – compounds which interfere with nutrient absorption. Key antinutrients in coffee include lectins and phytates.
Lectins act as natural insecticides in plants, but damage gut lining integrity in humans and promote inflammation along intestinal walls (21). Phytates chelate with minerals like zinc, magnesium, and calcium, obstructing efficient intake (22). High levels of consumption of these antinutrients are implicated in the development of chronic conditions.
Mold Toxins
Coffee’s other major downfall is susceptibility to mold contamination and accompanying mycotoxin accumulation during processing and storage. Investigations have identified toxic fungi like fusarium, ochratoxin A, and aflatoxin B in commercial coffee even post-roasting (23). Mycotoxins trigger cell mutation and have been correlated to carcinogenesis, liver toxicity, impaired kidney function, and neural damage (24). Not an ideal added ingredient alongside your morning brew!
Insomnia, Hormonal Imbalance and Obesity
The caffeine content itself compounds issues as well for strict carnivores. Caffeine possesses a half-life of up to 6 hours, disrupting natural circadian rhythms and sleep quality if consumed afternoon or night. Even small doses above 200mg per day may affect sleep efficiency (25). As little as 3 days limited sleep triggers insulin resistance and essentially “pre-diabetes” biomarkers (26).
Poor sleep also drives imbalanced hunger signals, raised cortisol, and cravings for empty carbohydrate calories. Harvard research links short sleep to increased risk of weight gain and obesity (27). This defeats fundamental goals of using the carnivore diet to stabilize blood sugar, resolve food addiction tendencies, and drop excess body fat.
Recommendations for Coffee & the Carnivore Diet
Within a carnivore framework that eliminates all other plant foods and common allergens, coffee introduces lectins, phytates, potential mold exposure, and caffeine to contend with. What guidance do functional medicine practitioners suggest given these variables?
Dr. Paul Saladino, a vocal advocate for strict carnivore eating, recognizes that some clients continue to incorporate coffee successfully. He states, "If you can have coffee, and you have no issues with it, great…I always say, look at it empirically for yourself” (28). Similarly, Dr. Ken Berry remarks, “If you drink coffee and you see no problems then keep doing that." (29).
Yet Saladino and others simultaneously recommend a 30-90 day “Clean Carnivore” elimination period without eggs, dairy or coffee to assess individual reactions. After adapting to purely meat and water, reintroducing coffee allows one to detect any impacts on energy, cognition, sleep quality, cravings, exercise recovery, or digestive issues.
If adding back coffee, functional medicine thought leaders advise restricting intake to one cup in the morning, shifting to decaf or herbal alternatives like chicory root later on, intentionally cycling off coffee weekly, and sourcing the cleanest beans possible. Let’s apply these best practices to construct an optimized daily meal plan:
7am: Drink 1 cup freshly brewed organic coffee
10am: Post-workout meal – fatty grass-fed burger patty and lamb liver
2pm: Ribeye steak with salmon roe side
8pm: Ground beef crumble bowl with bone broth
Prioritizing animal protein first thing prevents blood sugar spikes and crashes. Consuming coffee after a workout exploits boosted adrenaline and endorphin levels for heightened productivity. The large ribeye replenishes nutrients and electrolytes lost through physical exertion and caffeine diuresis (30) The final whole food meal provides building blocks for overnight muscle repair.
Coffee caveats aside, this structured approach allows one to harness selectivity and timing to maximize energy and health within the constraints of carnivorous eating.
Conclusion: Listen to Your Body’s Signals
To conclude, more extreme diets warrant more disciplined optimization of “gray area” foods like coffee. While potentially enhancing exercise performance and mental output, the downsides of antinutrients, impaired sleep, mold risk, and addiction may undermine progress if unchecked. Carnivores must balance coffee’s advantages against sensitivities unique to their physiology.
When it comes to hot-button topics like coffee, biohacker Ben Greenfield distills triggering questions to pinpoint one’s optimal consumption habits:
“Can you function without it?
Is it making you dependent upon it?
Is it causing insulin, blood sugar imbalances?
Does it disrupt your sleep if taken at inopportune times?” (31)
Rather than follow rigid restrictions, allow your body to answer these questions as you experiment strategically within a meat-based framework. Stay tuned as we uncover more insights into mastering the modern carnivorous lifestyle!
