12 oz cappuccino breve = 246 cal, 21 g fat, 9 g carb, 6 g protein (if this is from Starbucks)
chocolate croissant = 300 cal, 17 g fat, 34 g carb, 5 g protein (used Starbucks as example)
chocolate scone = 460 cal, 19 g fat, 67 g carb, 7 g protein (ditto Starbucks)
So this snack is giving you roughly 550 - 700 calories, 40 g fat, 44 - 75 g carb, 12 g protein.
If I were you, I'd replace this snack with something clean, like raw nuts and Kerrygold cheese (if you want the fats, which may keep you feeling full/satisfied longer), or a piece of fruit (if you want the healthier sugar/carb alternative), or a hard-boiled egg/cup of plain Greek yogurt (if you want a protein burst - add fresh fruit to the yogurt for a tasty alternative).
I find that if I'm primal/paleo for most of my daily food but the 20% daily comes from grains/highly processed foods, my body clings onto the grain/highly processed foods. Just the way it is for me. Maybe it's that way for you too.
