What should I know about keto ernahrung?

The ketogenic (keto) diet is a very low-carb, high-fat diet that induces ketosis. Short-term benefits include weight loss and improved blood sugar control, with some evidence for epilepsy and metabolic syndrome. However, long-term safety data are lacking. Risks include the 'keto flu', nutrient deficiencies, elevated LDL cholesterol, and kidney strain. Individual genetics (e.g., fat metabolism genes) may influence response, but direct-to-consumer genetic tests for keto are not well validated. Evidence is mixed: human studies exist but are often small or short-term, and marketing hype is common. Medical supervision is advised, especially for those with pre-existing conditions.
