GLOSSARY

Keto-Adaptation describes metabolic adaptation to a ketogenic intake pattern; a ketone reading alone does not establish complete adaptation or better performance.

Nutritional ketosis reflects increased ketone availability during marked carbohydrate restriction or fasting and differs from diabetic ketoacidosis. Early weight changes can include glycogen and water, so they should not all be called fat loss. Ketogenic interventions are not interchangeable with ordinary healthy eating or proven optimal for every sport. Diabetes medication, illness and symptoms can change safety; suspected ketoacidosis requires urgent medical assessment rather than interpretation as normal dietary adaptation.

A carbohydrate-defined diet needs an actual intake description, because labels such as low and moderate vary between studies and clinical settings. Lowering carbohydrate does not independently describe energy intake, fiber quality or protein adequacy. Athletes performing repeated intense work may find severe restriction incompatible with the desired training quality. Match the intervention to its medical or performance purpose and distinguish a temporary session-specific adjustment from a persistent restriction across all meals and training days.

Total fat amount and fat quality describe different aspects of a diet. Replacing saturated fat with appropriate unsaturated sources differs from simply adding oil or replacing fat with refined carbohydrate. Very low fat intake can make essential fatty-acid supply and overall adequacy harder to achieve. A high-fat diet is not necessarily ketogenic. Evaluate the actual foods, total energy and clinical aim while retaining enough carbohydrate and protein for the athlete's planned work.
