Coffee on Carnivore Diet: Pros, Cons, & All You Need to Know

It is no secret that coffee is a plant-based drink, a roasted seed extract, and the Carnivore Diet allows no plants. So, does it mean that we cannot have coffee on Carnivore Diet? Well, while it technically is not an animal-based food, many Carnivore dieters continue drinking it. Some say it is not Carnivore-friendly, others say it can even be beneficial for fat loss. So, let’s weigh the pros and cons and see if it is good to drink coffee on a Carnivore Diet.

Coffee on Carnivore Diet

The Carnivore Diet does not allow plant-based foods because it aims to minimize toxins, antinutrients, and irritants that come from plants to boost gut healing, improve metabolic health, and reduce inflammation.

So, coffee falls in a gray area since it is plant-based and contains non-Carnivore compounds. Yet, it is more than a drink, and some individuals feel stressed if they quit it.

Furthermore, coffee can have significant physiological effects on cortisol, sleep, digestion, and nutrient absorption. So, let’s dig deeper and find out whether it is worth it to drink coffee on Carnivore Diet.

What We Already Know About Coffee?

Coffee is not just a source of caffeine. It contains hundreds of bioactive compounds that influence metabolism and health.

The Main Components of Coffee

• Caffeine: It is a stimulant that blocks adenosine receptors, helping you feel alert [1].
• Chlorogenic Acids: These are plant polyphenols with antioxidant and metabolic effects [2] [3].
• Diterpenes (Cafestol, Kahweol): They influence cholesterol metabolism [4].
• Trigonelline and Minerals: They are trace compounds that can impact taste and physiology [5] [6].

General Health Impacts of Coffee

• Drinking coffee moderately can help reduce the risk of liver disease, Parkinson’s disease, and Type 2 diabetes [7] [8].
• Coffee contains antioxidants, which are especially good for those who do not consume fruits or vegetables [9].
• However, coffee can cause sleep disruption, anxiety, jitters, and increased heart rate in sensitive individuals [10].

The table below summarizes the main effects of coffee:

We also need to consider that, unlike grains, legumes, or leafy greens, coffee is consumed as an extract, not a whole plant food.

It means the carbohydrate content of coffee is too low, and what you mainly get from it are caffeine (a stimulant) and polyphenols (plant compounds with antioxidant effects).

So, the real question is whether the benefits of coffee outweigh the risks for those following a Carnivore Diet. The point that can shed more light on the topic is that coffee can behave differently in a body adapted to an all-meat, low-carb diet.

How Coffee Affects Those on a Carnivore Diet

When you are on a low-carb diet like Carnivore, your metabolism changes, and when you drink coffee, you may experience some effects more or less than those on high-carb diets.

So, let’s find out how coffee can impact cortisol, fat metabolism, insulin, blood sugar, mineral absorption, and the digestive system.

Caffeine and Cortisol

Caffeine increases cortisol and adrenaline, which can be boosted in those already running on higher stress hormones due to minimizing carbohydrates. This may cause anxiety, palpitations, or poor sleep [11] [12].

Fat Metabolism

When you increase protein and fat intake and minimize carbohydrates, your body gets fat-adapted gradually. Caffeine can also help increase fat mobilization (lipolysis) [13].

So, in a fat-adapted state, the caffeine content of coffee can synergize with the Carnivore Diet and fat metabolism, improving endurance and focus [14].

Insulin and Blood Sugar

Coffee can cause short-term rises in insulin and glucose in some individuals. While this impact is usually small and not significant, if you are on a zero-carb Carnivore, it can impact energy stability for sensitive people [15] [16] [17].

Mineral Absorption

Coffee can interfere with the absorption of iron, zinc, and magnesium. These minerals are critical on a Carnivore Diet, so drinking too much coffee on Carnivore Diet can reduce nutrient efficiency [18] [19].

Gut Barrier and Digestion

Coffee’s acidity and polyphenols can irritate individuals with sensitive guts. If you are on a Carnivore Diet to heal your problems, coffee can slow down your recovery [20] [21].

Evidence of Drinking Coffee in Carnivore and Low-Carb Communities

While no large-scale trials exist specifically on coffee and the Carnivore Diet, we can draw insights from surveys and community reports.

• Harvard Carnivore Study: 57% of respondents drank coffee daily while reporting improved health status [22].
• Reddit/ Forums: Many carnivores report they drink coffee on a Carnivore Diet and can tolerate it, though some eliminate coffee due to worsened anxiety, insomnia, or gut irritation.
• Ketogenic Studies: Research shows caffeine enhances fat oxidation and physical performance in athletes on low-carb diets.

So, what we can learn from these findings is that many of the individuals who are on a Carnivore Diet can tolerate coffee, but a significant minority experience issues. So, it is wise to try it and see how your body reacts.

Summary

Coffee is a plant-based drink, but many people tolerate it well and benefit from its energy, mental clarity, and liver-protective effects. Others experience sleep problems, anxiety, or gut irritation.

The safest approach is to test how your body reacts to coffee by eliminating coffee during adaptation, starting again carefully, and monitoring your body’s reactions.

All in all, the decision to include coffee on Carnivore Diet or not comes down to your goals and how your body reacts. On a Carnivore Diet, even small details like coffee can make a big difference in long-term success.

So, consider all factors before deciding on including or excluding foods and drinks.
