GLOSSARY

Refeeding Syndrome is a potentially dangerous metabolic response to restarting nutrition after depletion, requiring risk assessment and clinical management.

After prolonged inadequate intake, restarting nutrition can produce dangerous shifts in phosphate, potassium, magnesium, thiamine demand and fluid balance. Risk depends on the clinical history and assessment, not only current body mass. Refeeding syndrome differs from a routine planned carbohydrate refeed during dieting. People at substantial risk need a carefully managed clinical plan with monitoring and appropriate support. Abruptly adding large amounts of food or supplements without assessment is not a safe shortcut to recovery from severe undernutrition.

Malnutrition can occur across body sizes, including in a person with obesity. Assessment considers reduced intake or assimilation, disease-related inflammation, weight trajectory and relevant body-composition or functional findings. Undernutrition, overnutrition and individual micronutrient deficiencies describe overlapping but distinct problems. A stable or high body weight cannot exclude inadequate nutrient supply or muscle loss. In an athlete, declining intake, recurrent illness or unintentional weight loss deserves assessment rather than automatic praise for becoming lighter.

Nutritional rehabilitation restores adequate intake, nutrient status and function in a way matched to the cause and severity of depletion. Weight restoration can be one goal, but a scale increase alone does not establish full recovery of muscle, health or eating behavior. The time course and monitoring depend on disease, previous intake and refeeding risk. Coordinate food, clinical treatment and appropriate activity rather than treating recovery as merely adding a fixed number of calories until a target weight is reached.

Clinical nutrition translates assessment into an individualized intervention and evaluates the response. A disease name alone cannot define the prescription: disease stage, medication, symptoms, laboratory findings, intake and functional goals matter. Screening identifies possible risk, whereas a full assessment supports a nutrition diagnosis and care plan. A sports context adds training demands but does not remove clinical requirements. Coordinate care when medical and performance objectives interact instead of applying a standard athlete menu to every patient.

Laboratory markers provide information within a clinical context rather than a complete nutrition diagnosis. Albumin and prealbumin are affected by inflammation, fluid balance, organ function and other processes, so they should not be interpreted as direct isolated measures of protein intake or muscle mass. A reference interval is not automatically the optimal target for an athlete. Combine relevant tests with intake, physical findings, symptoms and trends, and consider the method and timing before attributing a result to diet alone.

A nutrition prescription specifies an individualized plan that can include energy, protein, other nutrients, fluid, food texture or route of delivery. The chosen body-weight reference, clinical condition and practical implementation must be clear when quantities are used. It should be monitored and revised as intake, treatment or health changes. In a clinical athlete, reconcile medical requirements with training rather than placing two incompatible prescriptions side by side and expecting the person to decide which one to follow.
