Eating accompaniment through shared mealtimes is a common strategy in eating disorder management programs. This study aims to examine the impact on weight gain of an internet-delivered meal support group on patients with AN who were under ambulatory treatment with the Eating Disorders Unit of the UC Christus Health Network, Chile. Methods: An observational study of 54 female patients with AN diagnosis who participated in Online Meal Support Groups (OMSGs) three times a week was performed. Their weight, BMI and BMI%, was reviewed at the beginning of the sessions and at 45- and 90-day follow-up. Results: Patients showed significant weight gain during follow-up. At the 90-day follow-up, patients had gained 4.41 (SD \u00b1 2.82) kg with an effect size of \u22121.563. Conclusions: Statistically significant differences were found between the weight at the beginning of the intervention and at the 45- and 90-day follow-up, meaning that eating support online groups may be an effective intervention for weight gain and maintenance in patients with AN. These findings highlight the viability of developing cost-effective and more accessible interventions for AN and thus help reduce the duration of untreated disease and its consequences.<\/jats:p>","DOI":"10.3390\/nu15173783","type":"journal-article","created":{"date-parts":[[2023,8,30]],"date-time":"2023-08-30T10:09:49Z","timestamp":1693390189000},"page":"3783","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Virtually Accompanied Eating in the Outpatient Therapy of Anorexia Nervosa"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0676-1831","authenticated-orcid":false,"given":"Melina","family":"Vogel","sequence":"first","affiliation":[{"name":"Eating Disorders Unit of the UC Christus Health Network, Santiago 8330077, Chile"},{"name":"Psychiatry Department, Faculty of Medicine, Pontificia Universidad Catolica, Santiago 8330077, Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aurora","family":"Gil","sequence":"additional","affiliation":[{"name":"Eating Disorders Unit of the UC Christus Health Network, Santiago 8330077, Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Camila","family":"Galaz","sequence":"additional","affiliation":[{"name":"Eating Disorders Unit of the UC Christus Health Network, Santiago 8330077, Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pascuala","family":"Urrejola","sequence":"additional","affiliation":[{"name":"Eating Disorders Unit of the UC Christus Health Network, Santiago 8330077, Chile"},{"name":"Adolescent Unit, Pediatrics Department, Faculty of Medicine, Pontificia Universidad Catolica, Santiago 8330077, Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lucas","family":"Lacalle","sequence":"additional","affiliation":[{"name":"Eating Disorders Unit of the UC Christus Health Network, Santiago 8330077, Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ra\u00fal","family":"Jara","sequence":"additional","affiliation":[{"name":"Eating Disorders Unit of the UC Christus Health Network, Santiago 8330077, Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ver\u00f3nica","family":"Irribarra","sequence":"additional","affiliation":[{"name":"Eating Disorders Unit of the UC Christus Health Network, Santiago 8330077, Chile"},{"name":"Nutrition and Diabetes Department, Faculty of Medicine, Pontificia Universidad Catolica, Santiago 8330077, Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Matias","family":"Letelier","sequence":"additional","affiliation":[{"name":"Eating Disorders Unit of the UC Christus Health Network, Santiago 8330077, Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daniela","family":"Costa","sequence":"additional","affiliation":[{"name":"Eating Disorders Unit of the UC Christus Health Network, Santiago 8330077, Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gabriela","family":"Espinoza","sequence":"additional","affiliation":[{"name":"Eating Disorders Unit of the UC Christus Health Network, Santiago 8330077, Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,8,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"70","DOI":"10.1016\/j.cppeds.2017.02.003","article-title":"Anorexia Nervosa\/Atypical Anorexia Nervosa","volume":"47","author":"Moskowitz","year":"2017","journal-title":"Curr.
