The study of food and diet through the principles of energy transfer, transformation, and metabolic efficiency. It goes beyond calories in/calories out to examine the thermic effect of different macronutrients (protein costs more to digest), the entropy of digestive processes, and how dietary composition influences metabolic rate and heat production. It's the science of eating as a thermodynamic engineering problem for the body.
Example: "Her nutritional thermodynamics approach was ruthless: 'That pastry is a high-entropy, fat-dense system with low thermic yield. It'll deposit energy with minimal metabolic work. This chicken and broccoli is a structured, high-protein load that'll raise my metabolic furnace temperature just breaking it down.' She was fun at bakeries."
