Good to Know
A 1 oz handful gives you 18.5g fat and 4.3g protein for 185 calories, which makes walnuts an easy snack or salad topper that fits the macros. Buy raw or dry-roasted halves and skip the candied or honey-glazed versions, since those add sugar that pushes the carb count up fast. Store them in the fridge or freezer because the high oil content means they go rancid quicker than most nuts, and toasting them lightly in a dry pan sharpens the flavor without changing the 2g net carbs.
