Ketogenic (Keto) Diet
Classic keto restricts carbohydrate enough to shift fuel use toward ketone production. It can lower glucose excursions for some adults and is used in specific medical contexts under supervision—but it is not casual dieting for everyone.
Recent guideline & evidence context: 2024–2026 discussions stress safety screening (lipids, liver, renal risk), medication interactions (insulin, SGLT2 inhibitors), and that long-term cardiovascular effects are individualized—not one-size-fits-all.
📊 Macros targetOften ~70–80% fat, ~10–20% protein, very low carbohydrate—targets vary by protocol.
