Background and Aim Literature suggests that individuals who have recovered from COVID‐19 may experience post‐COVID conditions, including sleep problems and alterations in smell or taste. Thus, this study aims to compare the sleep quality, diet quality, and weight change between COVID‐19‐recovered patients and healthy controls. Methods A matched case‐control study involving young adults aged 18–30 years was conducted in the Klang Valley of Malaysia. The young adults were matched in a 1:1 ratio based on their sociodemographic characteristics, including gender, age, marital status, ethnicity, educational attainment, employment status, and monthly earned income. The Pittsburgh Sleep Quality Index was utilized to evaluate sleep quality, and the Diet Quality for Malaysia was used to determine the diet quality of all young adults. The young adults retrospectively recalled their prepandemic body weight in February 2020, while their current body weight in February 2023 was measured using a TANITA HD‐314 digital weighing scale. Results Emerging findings suggest that sleep quality and weight change were comparable between COVID‐19‐recovered patients and healthy controls. However, healthy controls were reported to have a more diversified diet than COVID‐19‐recovered patients. Nevertheless, no significant main effects or interaction effects of sleep and diet quality on weight change were observed in COVID‐19‐recovered patients or healthy controls. In this study, young adults also reported suffering from sleep deprivation and deficiency due to the pandemic. Conclusion Intervention programs that emphasize avoiding stimulants before bedtime for healthy controls, promoting the importance of having a diversified and balanced diet among the COVID‐19‐recovered patients, and achieving an ideal body weight for all young adults should be conducted after the COVID‐19 pandemic.
