Will Athletic Greens Break An Intermittent Fast?

When determining whether or not a food or supplement will break your fast, you need to take a glance at the Nutrition (or in this case Supplement) Facts Label. The goal with Intermittent Fasting is to keep insulin from spiking. The foods that spike insulin are carbohydrates and, to a much lesser degree, protein.

There's not a hard rule on exactly how many grams of either carbohydrates or protein will spike insulin (as it can vary per person), however to be on the safe side, I personally go by the 1 gram rule. This means keeping the total grams of protein and carbohydrates under one net gram.

Looking at Athletic Greens, one serving contains 6 grams of carbohydrates and 2 grams of fiber. This equates to 4 net grams of carbohydrates. One serving of Athletic Greens also contains 2 grams of protein.

With the carbohydrates alone, Athletic Greens will contain more than 1 net gram carbohydrates and therefore will break a fast. With this in mind, if you're using Athletic Greens, you'll want to keep it during your eating window.

Can You Drink Green Juice While Intermittent Fasting?

Taking a look at green juices that exclusively use vegetables and no fruit, 12 oz. will contain at least 8-10 grams of carbohydrates. This level of carbohydrates will break a fast and therefore should be used during the eating window, not the fasting window.

If you're adding fruit into your green juice, this can greatly increase the carbohydrate count. For example, a green juice that uses apple contains around 33 grams of carbohydrates, 28 of which comes from sugar. This most certainly will break a fast and spike the storing hormone insulin.

If you're juicing while working toward a weight loss goal, it's important to keep your juice free of fruit and only have it during your eating window.

Do All Supplements Break A Fast?

Not all supplements will break a fast. If the supplement doesn't contain any protein or carbohydrates, it likely won't break a fast. For example, pure vitamins or minerals will not break a fast. But if those vitamins or minerals come in the form of a sugary gummy, then that WILL break your fast. Always check the supplements facts label to see if your supplement contains protein or carbohydrates in order to determine whether or not it will break a fast.
