Does Cinnamon Break Intermittent Fasting

While intermittent fasting, it can be tempting to find some way around the “water only” requirement. Adding a bit of flavor to get you through the fast is what we’re all looking for. Luckily, drinks like coffee and tea are perfectly acceptable to have as neither has the necessary nutrients to trigger your insulin production and break your intermittent fast.

However, plain black coffee can be quite difficult to swallow. It will curb your hunger and distract you from any cravings for sure, but only if you can get it down. For those of us who detest plain black coffee but are still seeking its benefits, there’s always that spoonful of cinnamon. But won’t cinnamon break your fast? It’s a spice, after all, and many spices can break fasts.

Let’s take a closer look at cinnamon to see whether or not a little bit of it will be enough to break your body’s intermittent fast.

Breaking Down Cinnamon

We’ll start by looking at a teaspoon of cinnamon to see what exactly you’re putting in your body. One teaspoon of pure, ground cinnamon contains 0.8 grams of carbohydrates and 0.1 grams of proteins. Those numbers might not sound like a lot, but when compounded or mixed with other spices, they’ll be enough to break a fast’s threshold.

A teaspoon of cinnamon also contains 6 calories – well below the ketosis threshold of 50 – and 0.1 grams of sugar. You’ll need to be very careful when having cinnamon as the sugar count can easily stack up and trigger an insulin production response which breaks your fast. When your insulin production is inactive, your body is burning fat for fuel so you want to stay in this state for your fast to continue.

One teaspoon of cinnamon shouldn’t break your fast as long as it’s pure, ground cinnamon. Some variants can have over 2.1 grams of carbohydrates which will certainly break your fast. As long as the amount of protein, sugars, and carbohydrates are below the insulin response threshold, you should be fine to have cinnamon in your coffee.

How Cinnamon Affects Your Fast?

You’ll really be pushing it with cinnamon and you should be careful when having it during an intermittent fast. Some experts have pinned 1 gram of protein and carbohydrates as the body’s breaking point for fasting. If you go above 1 gram of each, your insulin production response will be triggered and you’ll have broken your fast. As we saw when breaking down cinnamon, the levels of protein and carbohydrates are just barely below that threshold.

So, with one teaspoon of ground cinnamon, you will still technically be below the insulin response threshold. However, if the teaspoon of ground cinnamon is mixed with other spices, you could be pushing past that maximum amount. Make sure to keep your protein and carbohydrate intake as close to zero as possible, otherwise your fast may break and ruin your progress.

All in All

Just be cautious when eating cinnamon during an intermittent fast. It might not be enough to break the fast on its own, but you never know what else might be mixed in with your coffee. One teaspoon of cinnamon is okay to have while intermittent fasting but make sure that it’s pure and that it doesn’t break the insulin production threshold.

Once your insulin production is triggered, your body will no longer be burning fat for fuel and you’ll find the effects of intermittent fasting to be much less potent. Just be aware of how much cinnamon you’re having and if anything else you’re ingesting while intermittent fasting breaks the fast.
