What specific task requires modern engines to manage adaptive needs differently than Stigler's static plan?

Answer

Dynamically adjusting recommended macronutrient ratios after a high-intensity workout.

Stigler’s approach provided a static, cost-optimized plan based on fixed minimum requirements. Modern engines, however, must manage adaptive needs derived from continuous monitoring of user activity and state. A clear example is how a system must react to a high-intensity workout logged by a user; the engine must immediately recalculate and dynamically adjust the recommended macronutrient ratios for subsequent meals or the following day to account for increased energy expenditure and recovery needs. This continuous, real-time recalculation based on changing user input is a core feature of modern engine functionality absent in static models.
