Built around a protein target, then constrained by the 180cal rule.
The calculator estimates a daily protein target from body weight and goal, subtracts protein already eaten, then searches the current 180cal catalog for one-to-three serving snack paths. The output is deliberately practical: protein, calories, price context, product detail pages, and Amazon handoff links stay in the same view.
180cal supports discovery and planning. Amazon controls the live seller, price, delivery promise, checkout, returns, and fulfillment.
