What is Keto?

A keto diet involves restricting carbs and sugars to get the body into a state of ketosis. There are several types of keto diet, and the standard version is composed of over 70% fat, 20% protein and less than 10% carbohydrates. When fat is the body’s primary source of energy, it pushes the body to react with a biochemical process known as ketosis.

Ketosis is when the body breaks down the body’s fat stores and creates ketones while fat is burning. Regular blood tests (or urine test) can show the level of ketones in your body if you want to track it very closely.

On a keto diet, the goal is to avoid excess carbs and sugar. This means no pasta, bread, crackers, or most types of fruit. You can still consume meat, low-carb veggies, and other healthy snacks.

Is Coffee Keto-Friendly?

Thankfully, your morning cup of freshly brewed caffeine can remain a part of your lifestyle. Coffee has very few calories (about 5 per cup), no sugar, and no carbs. Black coffee does not affect your keto diet. Adding in dairy and sugar can affect your diet. Avoid high-fat mixers, heavy cream, and sugar.

How Many Net Carbs In Coffee?

There are 0g of carbs in straight black coffee, according to the USDA.

Caffeine and Ketogenesis

Caffeine may actually be beneficial to your keto diet. It can help raise ketone levels and can help your body remain in a state of ketosis. Studies show that keto dieters who had their morning coffee had higher levels of ketones in their bloodstream compared to those who didn’t.

Caffeine can also curb your appetite, which can be helpful as you adjust to a keto diet.

What is Keto Bulletproof Coffee?

Bulletproof coffee is black coffee or espresso that is blended with grass-fed butter and MCT oil. This helps create froth with healthy fats instead of dairy. It is also known as keto butter coffee. It contains lots of fat so it not only satisfies your caffeine craving but keeps you fuller, longer.

Be sure to get sugar-free coffee syrup that is sweetened with aspartame, sucralose, or neotame. Sugar is not allowed in your keto diet.

Keto Coffee Creamers

There are a few coffee creamers you can choose from that are keto-friendly. You can use MCT oils like coconut oil or olive oil, unsweetened almond milk, heavy whipping cream, full-fat coconut milk, grass-fed butter, unsweetened cocoa powder, plain Greek yogurt, or other creamers made from nuts or dairy.
