Synonym discussion
Sense: adjective/1
These terms all describe food and drink with a reduced energy content. Low-calorie is the most neutral and precise label, used on official nutrition panels. Diet is a marketing term common on sodas and snacks that use artificial sweeteners, but a diet product may still have a similar calorie count to the regular version. Light can mean lower in fat, sugar, alcohol, or calories depending on the country and product — it is the vaguest of the group. Low-fat refers specifically to fat content rather than calories, and some low-fat items actually add sugar to improve taste, keeping the calorie count high. Reduced-calorie is a regulated term in many markets, typically requiring at least 25% fewer calories than the standard version. For example, light mayonnaise may have less fat but the same number of calories as regular mayonnaise, whereas reduced-calorie mayonnaise must contain measurably fewer calories by law.

Etymology
Formed by combining the English adjective low (from Old English lāh, meaning 'not high' or 'below average') with the word calorie (from French calorie, based on Latin calor meaning 'heat'). The compound came into everyday use in the mid-20th century when food manufacturers began producing products with reduced energy content for people managing their weight or health conditions.
