Calories In, Calories Out Is Real…But It’s Only Part of the Equation
 

Let’s talk about the phrase you see alllll over social media: calories in, calories out.

According to the internet, it’s the *only* thing that matters. Just “eat less, move more,” and BOOM - problem solved.

But…there’s a WHOLE lot of “fine print” that gets skipped over here. If you’ve ever felt like CICO “doesn’t work” for you, this episode is going to clear it up!

Yes, calories in, calories out IS the foundation, but there is sooo much that influences those calories. Factors like hormones, stress, sleep, perimenopause, thyroid issues, insulin resistance, medications, and more ALL play a part! 

Calories in, calories out is absolutely real - it's the basis of every fat loss strategy out there. However, it’s NEVER going to be *just* your calorie intake that will lead you to reach your fitness goals.

Make sure you’re using a smarter plan, and actually follow it - not your mood. That alone will help you greatly, friend!
