It is believed that COVID-19 is spread via person-person contact, through respiratory droplets and because of this social distancing, hand washing, and wearing face coverings is crucial to reduce the spread of the virus ( 2).Īs of July 2020, there have been over 570,000 global deaths related to COVID-19 ( 3). Currently, little is known of the transmission, mechanism, and treatment of COVID-19. In March 2020, the World Health Organization (WHO) declared the coronavirus outbreak as a global pandemic ( 1). Both in the short term and if sustained in the long term, these changes may have significant impacts on the health of the population. In eight studies participants reported weight gain with seven studies reporting a reduction in physical exercise.Ĭonclusion: The effect of COVID-19 lockdown both negatively and positively impacted dietary practices throughout Europe and globally, and negative diet habits were associated with other poor lifestyle outcomes including weight gain, mental health issues, and limited physical activity. Two studies reported an increase in alcohol consumption.
However, nine studies found a reduction in fresh produce, with a further six reporting an increase in comfort foods including sweets, fried food, snack foods, and processed foods. Eleven studies reported favorable changes in dietary habits with an increase in fresh produce and home cooking and reductions in comfort food and alcohol consumption. A total of 10 studies reported an increase in the number of snacks consumed, while six studies found that participants increased their meal number and frequency during quarantine. Four themes were identified: dietary patterns, dietary habits (favorable), dietary habits (unfavorable), and other (includes physical activity levels, weight gain). Results: Four thousand three hundred and twenty-two studies were originally considered with 23 final full-text papers included. Researchers agreed on the study characteristics for extraction from final papers. Exclusion criteria were as follows: papers examining dietary changes in those following a structured diet based on diagnosed conditions or dietetic advice literature, systematic, or narrative studies reviewing previous research. The inclusion criteria of this search included: papers published (or in pre-print) in the year 2020 studies that investigated the impact of COVID-19 lockdown on diet papers published in English.

Methods: Between June and July 2020, the PubMed, Google Scholar, and Science Direct databases were searched, and results were screened for eligibility based on title, abstract, and full text. Themes and patterns were considered and associations with other lifestyle factors were assessed. The aim of this review was to assess dietary changes during the first lockdown.
However, more time at home may have resulted in some positive habits including an increase in cooking. 2Centre for Movement Occupational and Rehabilitation Sciences, Department of Sport, Health Sciences and Social Work, Faculty of Health & Life Sciences, Oxford Brookes University, Oxford, United Kingdomīackground: Since the beginning of the COVID-19 pandemic, access to fresh food has been restricted, and people are spending more time inside and have limited their physical activity.
