"Caloric deficit" can be a really scary or intimidating term if you've never thought about macronutrient counting before (or sometimes, even if you have)... but it's actually a pretty simple concept once you understand the science behind it.  That's exactly what I'm here to share in this week's episode of Crash Course - not only what a deficit IS, but how to calculate the RIGHT deficit the RIGHT way.  All of which matters if you have specific health goals you're looking to achieve.  And don't worry - you won't even need a calculator for this one :)
