The form matters enormously. Salted, shelled, visible nuts in a jar on the counter are essentially a different food from unsalted, in-shell nuts stored in a cabinet. Research by Honselman found in-shell pistachios resulted in 41% fewer calories consumed than pre-shelled. The first configuration promotes continuous, mindless consumption; the second creates friction that keeps portions reasonable.
This companion covers the nut paradox (healthy but calorie-dense), the variables that matter (salt, shell, visibility), the worst versus best configurations, conducting the audit, and making changes to how you keep nuts. (5 min read)
