A Keto diet can be complex and confusing for some people. Determining what to eat, when to eat, and the role those foods impact the natural processes inside your body can be overwhelming. However, the benefit of a Ketogenic Diet can be significant healthy weight loss.

When we take away foods that provide comfort, we can add a new level of stress. But, what about replacing them with alternatives? Being miserable on a diet just is not going to work long-term.

There’s lots of coffee drinkers out there, and we know that caffeinated coffee can kick you out of ketosis. This is because once the caffeine enters your blood stream it can have a short-term effect on your blood sugar and insulin levels. But, what about decaf coffee?

Switching to decaf may be a great way to experience the “comfort” of coffee, without all the caffeine that can be detrimental to your Ketogenic Diet. Of course, over the first few days you may feel some slight withdrawal symptoms. That’s just  your body adjusting to the caffeine leaving your system.

Decaf coffee should not kick you out of ketosis. Of course, this also means not adding sugar to the coffee, and keeping in mind that artificial sweeteners will have various effects on ketosis as well. My research has shown that Stevia is one of the best sweeteners out there for Ketogenic diets. It does not cause blood sugar or insulin levels to spike after consumption.

However, it is important to know what you are putting into your body. Not all decaf coffee is created equal. Many decaf coffees actually are not “caffeine free”, as they still contain smaller amounts of caffeine in them. This is where investigation and monitoring are going to play huge roles in maintaining your “keto discipline”.

Time of day is certainly going to play a factor as well. Since we tend to deplete ketone’s at night while we are sleeping, you may find yourself waking up not in ketosis, even before sipping that first cup of coffee, decaf or otherwise.

It’s important to know what works best for you. Monitor your progress closely, and try different combinations of strength, sweeteners, and additional ingredients. You may find that some work well and keep you in ketosis, while others quickly kick you out, making it harder to lose weight successfully. It’s about trial and error, and finding out the combination that works within your own body.

    Thanks for the tip. I live where Stevia sweetener is not available but I am sure I can find somewhere online to order it and have it shipped or mailed.

      Have you tried Amazon? I think that they are offering some discounts for anyone who is new to their pantry service.

      Are you still unable to get Stevia?

    Very interesting. I drink a lot of coffee. Sometimes I consume too much for my health but I do not smoke so I guess it is filling the same need. I use sweetener so no calories are consumed, but I should probably switch to decaff. I never knew all decaff coffee was not the same. I assume coffee minus caffeine was decaff.

    I have read that other places the “decaf” is just a little bit of caffeine, for some brands. Could that be a bad thing if you typically have a reaction to caffeine?

      It could be a bad thing? It’s probably going to depend on how you metabolize that caffeine, and how much is “a little”.
