According to the National Heart, Lung, and Blood Institute (NHLBI), a healthy rate of weight loss is approximately 0.5 kg (1 lb) per week, sustained over up to six months for long-term success (NHLBI, NIH). Additionally, the UK National Health Service (NHS) recommends a gradual weight gain of 300–500 kcal per day, which typically results in a gain of approximately 0.2–0.4 kg (0.5–1 lb) per week, especially in individuals with an energy requirement around 2000 kcal/day (NHS).
