The Crossfitter’s Guide to Intermittent Fasting

Whether you’re a die-hard, competitive Crossfitter, or you’re just breaking into the Crossfit scene, you’ve probably heard the term 'Intermittent Fasting' floating around your box or local gym. And rightfully so.


I won’t get too far into the weeds in this post, but the benefits include added convenience, lower blood sugar levels, increased insulin sensitivity – and did I mention, lower body fat percentages?

Eating 5-6 small meals a day is pretty much the norm amongst Crossfitters, due to claims that it’ll keep blood sugar in check, but a careful look shows that having more frequent meals actually elevates your baseline blood sugar levels ¹. Higher blood sugar levels lead to insulin resistance and glucose intolerance as well. By allowing you to eat fewer (and yes, larger) meals in a shorter time span, Intermittent Fasting keeps blood glucose, insulin intolerance, and glucose resistance all in check.

But it gets better…

Increased insulin sensitivity also means increased leptin sensitivity. Leptin is the signal that tells our brains we’re full, and our bodies to stop storing fat, so we want to be sensitive to it– the sooner our bodies hear that leptin signal, the sooner we’ll put the fork down. Increased leptin sensitivity (and thus, lower body fat levels) is yet another benefit of Intermittent Fasting.

Not to mention, eating all 3 meals in an 8-10 hour span increases your satiety, meaning it’ll be a lot easier for you to put down that extra cookie!

Now that you’ve got the basics of Intermittent Fasting down, let’s get to the good part.
