I know meal prepping your snacks might sound a little boring and unnecessary, but here me out: snacks can be a powerful tool for upping your nutrition!
That’s right, snacking isn’t a bad habit- it can actually be incredibly useful in maintaining stable energy levels, adding in extra nutrients, and preventing you from arriving at the next meal STARVING and eating past satiation. The real thing to focus on isn’t snacking itself, but what snacks you choose!
Listen, I know it can be easy to reach for packaged snack foods. They are easy, convenient, and tasty- aka the criteria for a go-to snack. But when I’m focusing on snacks as a nutrition tool, I also like to make sure my snacks are balanced and satiating too, so they actually keep me full until the next meal.
