What if understanding macronutrients could make nutrition feel way less confusing?
A lot of us hear terms like calories, protein, carbs and fats and only consider macronutrients in the form of “tracking macros” all the time. Rarely do we learn what important roles all macronutrients play in our bodies. So instead, we end up fearing food groups, obsessing over numbers, or feeling like we’re constantly eating “wrong” without fully understanding why.
If you’ve ever felt guilty for eating carbs, scared of fats, confused by calories or overwhelmed by constantly tracking numbers, this episode is for you.
