GLOSSARY

Overnight Fasting is the interval without energy intake spanning the usual overnight period.

Fasting patterns alter when food is eaten and sometimes reduce total energy intake, but the timing rule alone does not guarantee weight loss or superior health. Distinguish the fasting interval from the eating interval and check actual energy and nutrient supply. Training quality, recovery, medication and a history of disordered eating can affect suitability. A restricted eating window that repeatedly prevents adequate fueling is not a successful sports-nutrition strategy merely because the schedule is followed.

Meal frequency, timing, size and daily nutrient distribution describe different features of eating. There is no universally optimal schedule independent of the person's circumstances. Consider training opportunities, appetite, gastrointestinal comfort, sleep and medication. An early or late meal should be interpreted within the whole day rather than automatically classified as beneficial or harmful. For an athlete with repeated sessions, practical access to food can matter more than imposing a fashionable timetable.

An adequate diet provides sufficient energy and essential nutrients while fitting health needs. A high score for variety or a healthy food label cannot independently demonstrate adequacy. Review what is actually eaten, including foods excluded and suitable replacements. Athletes can consume many vegetables yet still lack enough energy or carbohydrate for training. Assess the overall pattern, distribution and relevant nutrient risks rather than assuming that a single food or supplement makes the entire diet balanced.
