Ketosis induction via carbohydrate limitation

Ketosis induction via carbohydrate limitation refers to the metabolic process by which restricting dietary carbohydrates—typically to less than 50 grams per day—leads to depletion of glycogen stores and triggers the liver to produce ketone bodies from fatty acids through β‑oxidation. This shift provides an alternative energy source for organs such as the brain when glucose availability is low. The resulting state of elevated blood ketones is called nutritional or dietary ketosis. This process underlies several therapeutic diets including the ketogenic diet and its variants (very-low-carbohydrate KD, medium-chain-triglyceride KD). While not itself a druggable molecular target like an enzyme or receptor, this metabolic pathway has significant clinical relevance for weight loss, glycemic control in type 2 diabetes mellitus, epilepsy treatment, and potentially other chronic conditions such as neurodegenerative diseases and cardiometabolic disorders. Safety concerns include transient side effects during adaptation (“keto flu”) and possible increases in LDL-cholesterol among certain individuals.
