                                While both the protein-sparing modified fast (PSMF) and ketogenic diets induce ketosis, they are fundamentally different in their nutritional composition, calorie levels, and purpose. A PSMF diet, for instance, is a very-low-calorie, high-protein plan designed for rapid fat loss under strict medical supervision, unlike the standard high-fat ketogenic diet used for longer-term metabolic management.
