Caffeine And Keto: Free To Enjoy?

Caffeine is a stimulant found in coffee, cacao, and guarana plants. It is a popular way to boost energy, and many people start their day with a caffeinated drink. But is it keto-friendly?

The good news for keto dieters is that caffeine, in its purest form, is a bitter-tasting white powder that is calorie and carb-free. However, the way you consume caffeine is crucial. Caffeine is ketogenic, but adding sugar or high-carb milk can kick you out of ketosis.

So, if you're on a keto diet, it's best to avoid adding sugar, sweeteners, or high-carb milk to your coffee or tea. Instead, you can add good fats like grass-fed butter or premium-quality MCT oil to make a drink similar to Bulletproof Coffee. Alternatively, you can add cinnamon, cardamom, or nutmeg to your tea for flavour and sweetness without the carbs.

Caffeine is keto-friendly

Caffeine is a natural stimulant found in the fruit, leaves, and beans of coffee, cacao, and guarana plants. It is nearly calorie and carb-free, making it keto-friendly. However, it is important to be mindful of how you consume caffeine while on a keto diet.

Benefits of Caffeine While on Keto

Caffeine can suppress your appetite and increase the breakdown of fat, thereby helping your body stay in ketosis. It also protects against fluctuating blood sugar levels and reduces the risk of diabetes.

Make Your Caffeine Count

While caffeine has many health benefits, especially for those on the keto diet, it is important to monitor your intake. Too much caffeine can cause health issues such as anxiety, insomnia, digestive issues, high blood pressure, and rapid heart rate. The ideal amount of caffeine varies from person to person and should be based on how it makes you feel.

Keto-Friendly Caffeine Options

• Black tea: Contains less than 1 gram of carbs per cup and can be enjoyed hot or cold. Add flavor with spices like cinnamon, cardamom, or nutmeg.
• Green tea: High in antioxidants and renowned for its healing and anti-cancer properties. Enjoy it hot or cold with a slice of lemon and mint leaves over crushed ice.
• Bulletproof Coffee: Made with the finest grade black coffee, grass-fed butter, and premium-quality MCT oil.
• Yerba Mate: A popular ingredient in energy drinks and health elixirs, yerba mate is made from the leaves of the mate tree and provides antioxidant benefits, reduces stress on the liver and heart, and prevents factors that lead to heart disorders.
• Kombucha: A bubbly, probiotic health drink made from bacteria, yeast, black or green tea, and sugar. Kombucha contains less sugar than other drinks and provides a small caffeine boost.
• Guarana: A caffeine-rich fruit native to the Amazon basin, guarana is often used to create medicinal drinks that help with ailments like depression and poor memory. It increases fat metabolism, enhances weight loss, and boosts energy.
• Matcha: Made from finely ground green tea leaves, matcha provides three times the caffeine of steeped tea and induces a calming buzz due to its l-theanine content. However, matcha should be consumed in moderation due to its high lead content.

Coffee is keto-friendly

Coffee addicts can breathe a sigh of relief: coffee is 100% keto-friendly. Traditional hot or cold brew coffee has zero calories and carbs, so you can still enjoy your favourite caffeinated beverage while on the keto diet.

Customising Your Coffee

The sugars and carbs only come into play when syrups and sweeteners are added. If you want to add a dash of something sweet to your keto coffee, you can add natural, high-fat foods such as a hearty dollop of heavy cream, or grass-fed butter if you're adhering to the Bulletproof diet.

Several brands now sell specialised sweeteners that accommodate a keto diet, such as Stevia, or you can add keto-friendly milk alternatives such as almond or coconut milk.

Coffee and Intermittent Fasting

If you're practising intermittent fasting, a plain black coffee would be fine during your fasting period. However, adding milk or cream may be considered breaking your fast, as these additions contain calories.

Caffeine can aid ketosis

Caffeine can stimulate ketone production, which is essential for ketosis. A study published in the Canadian Journal of Physiology and Pharmacology found that caffeine intake increased plasma ketones in humans. The study involved administering two doses of caffeine (2.5 and 5.0 mg/kg) to 10 healthy adults and observing a significant increase in ketone production in a dose-dependent manner (+88% and +116%, respectively).

Additionally, caffeine's ability to boost metabolism and promote lipolysis (the breakdown of fats) can further contribute to ketosis. Caffeine may also raise plasma free fatty acids, which can be used for energy when carbohydrates are scarce.

However, it is important to note that some sources suggest that caffeine might increase insulin resistance, which could theoretically hinder ketosis. Nevertheless, the overall impact of caffeine on ketosis appears to be positive, and it can be a useful tool for those seeking to take advantage of the potential benefits of ketosis.

Caffeine has health benefits

Caffeine has a wide range of health benefits, from improving mood and brain function to boosting exercise performance and protecting against several diseases. Here are some key ways in which caffeine can positively impact your health:

Improved Mood and Brain Function

Caffeine can block the brain-signalling molecule adenosine, which increases other signalling molecules like dopamine and norepinephrine. This change in brain messaging is believed to enhance mood and brain function. Studies have shown that consuming 37.5-450 mg of caffeine improves alertness, short-term recall, and reaction time. Additionally, drinking 2-3 cups of caffeinated coffee per day is linked to a lower risk of suicide and depression.

Boosted Metabolism and Fat Burning

Caffeine stimulates the central nervous system, which may increase metabolism by up to 11% and fat burning by up to 13%. Consuming 300 mg of caffeine daily can help burn an extra 79 calories, which can prevent the average yearly weight gain. However, the long-term effects are likely to be small, as a 12-year study found only a minor difference in weight between high and low coffee drinkers.

Enhanced Exercise Performance

Caffeine may increase the use of fat as fuel during exercise, helping to preserve muscle glucose and delay exhaustion. It also improves muscle contractions and increases tolerance to fatigue. Research shows that consuming 2.3 mg of caffeine per pound of body weight about an hour before exercise can improve endurance performance by up to 5%.

Protection Against Heart Disease and Diabetes

Contrary to popular belief, caffeine does not increase the risk of heart disease. In fact, drinking 1-4 cups of coffee daily is associated with a 16-18% lower risk of heart disease in both men and women. Additionally, regular coffee drinkers have a lower risk of developing type 2 diabetes, with a 29% lower risk for those drinking the most coffee and a 30% lower risk for those consuming the most caffeine.

Other Benefits of Coffee Consumption

Coffee consumption is linked to a reduced risk of liver damage, with a potential decrease of up to 84%. It may also decrease the risk of premature death by up to 30%, especially for women and people with diabetes. Drinking 2-4 cups of coffee per day is associated with a reduced risk of liver cancer by up to 64% and colorectal cancer by up to 38%. Coffee may also lower the risk of skin cancer by 20% when consuming 4 or more cups of caffeinated coffee daily.

Avoid caffeine with sugar

Sugar is a common ingredient that is added to caffeine, especially in coffee and tea. However, it is important to be cautious when consuming caffeine with added sugar, as both substances can have negative impacts on health when consumed in excess. Here are some reasons why you should avoid caffeine with sugar:

Heart Disease and Stroke:

Excess sugar consumption increases the risk of premature heart disease and stroke. Caffeine can also contribute to heart disease by triggering an adrenaline-like reaction in the body, affecting heart rate. Therefore, combining caffeine and sugar can potentially increase the risk of cardiovascular issues.

Weight Gain:

Sugar-sweetened beverages, such as colas, energy drinks, and sports drinks, are a major source of extra sugar in the diet. These drinks not only provide empty calories but also interfere with the body's appetite control system, leading to increased calorie intake and weight gain.

Blood Pressure and Chronic Inflammation:

High sugar intake is linked to high blood pressure, which increases the risk of heart disease and stroke. Additionally, sugar promotes chronic inflammation in the body, putting extra stress on the heart and blood vessels, further elevating the risk of premature death and stroke.

Negative Impact on Arteries:

Consuming excess sugar leads to high levels of triglycerides and "bad" LDL cholesterol, which can clog the arteries supplying oxygen to the heart. This, combined with the effect of caffeine on heart cells, can create a dangerous combination for cardiovascular health.

Energy Boost and Health Concerns:

While sugar provides an instant energy boost, it is important to remember that this energy is short-lived and can lead to energy crashes later. Additionally, the combination of caffeine and sugar can mask the actual amount of caffeine consumed, leading to potential overconsumption and associated side effects such as jitters, anxiety, and insomnia.

To maintain a healthy diet and reduce the risk of health complications, it is best to minimise the addition of sugar to caffeinated beverages. Instead, opt for natural sweeteners like stevia or erythritol, or use keto-friendly alternatives such as unsweetened plant-based milk in your coffee or tea.
