Adolescents followed a very low-energy diet and intermittent energy restriction (IER) or continuous energy restriction (CER). This study explored adolescents\u2019, parents\u2019, and dietitians\u2019 perspectives of the intervention. Methods: A convergent parallel mixed-methods evaluation was conducted. Acceptability questionnaires were collected from adolescents (week 16: n = 113, week 52: n = 88) and parents (week 16: n = 108, week 52: n = 80). Semi-structured interviews were conducted with adolescents (n = 14), parents (n = 11), and dietitians (n = 6) at week 52. Interview transcripts were thematically analysed. Results: Adolescents rated enjoyability (score 0\u2013100) at week 16 (mean [SD] IER: 63.5 [21.1] vs. CER: 65.9 [20.2], p = 0.550) and week 52 (IER: 67.2 [18.1] vs. CER: 61.0 [23.4], p = 0.198), showing no significant difference between groups. Most parents reported benefits at week 16 (IER: 86% vs. CER: 93%, p = 0.263) and week 52 (IER: 79% vs. CER: 83%, p = 0.717). Adolescents positively rated their experience with dietitians. Qualitative feedback emphasised the impact of clear dietary advice, easy and frequent access to support, continuity of care, and family engagement. Conclusions: This evaluation offers insights into a specialised dietary intervention for adolescents. Findings can inform future obesity treatments for adolescents in outpatient tertiary healthcare settings.<\/jats:p>","DOI":"10.1159\/ofa\/adzag010","type":"journal-article","created":{"date-parts":[[2026,9,4]],"date-time":"2026-09-04T11:21:17Z","timestamp":1788520877000},"page":"1-1","source":"Crossref","is-referenced-by-count":0,"title":["Exploring the Acceptability of a Specialist Obesity-Treatment Intervention (Fast Track to Health) for Adolescents: A Mixed-Method Study"],"prefix":"10.1159","author":[{"given":"Sarah","family":"Lang","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eve T.","family":"House","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Natalie B.","family":"Lister","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hiba","family":"Jebeile","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Johanna","family":"Hoare","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kaitlin","family":"Day","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Megan L.","family":"Gow","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mary-Kate","family":"Inkster","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Justin","family":"Brown","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Helen","family":"Truby","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"name":"on behalf of the Fast Track to Health Study team","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[2026,9,8]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1038\/nrendo.2017.147"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1111\/obr.13132"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1002\/oby.24336"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1007\/s00125-016-4163-5"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1186\/s12887-014-0289-0"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1093\/jn\/nxz049"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1016\/j.orcp.2019.11.005"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1001\/jamapediatrics.2024.2869"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1001\/jamapediatrics.2024.2851"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.3390\/nu16183125"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1186\/s13012-021-01171-7"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1111\/bjhp.12295"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.3390\/socsci8090255"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1186\/s43058-021-00174-1"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.1177\/1367493514551307"},{"key":"ref16","doi-asserted-by":"publisher","DOI":"10.1016\/j.jbi.2019.103208"},{"key":"ref17","doi-asserted-by":"publisher","DOI":"10.1016\/j.jbi.2008.08.010"},{"key":"ref18","doi-asserted-by":"publisher","DOI":"10.1186\/1471-2288-13-117"},{"key":"ref19","doi-asserted-by":"publisher","DOI":"10.1093\/intqhc\/mzm042"},{"key":"ref20","doi-asserted-by":"publisher","DOI":"10.1186\/s12913-017-2031-8"},{"key":"ref21","doi-asserted-by":"publisher","DOI":"10.1111\/obr.12771"},{"key":"ref22","doi-asserted-by":"publisher","DOI":"10.1111\/dme.14066"},{"key":"ref23","doi-asserted-by":"publisher","DOI":"10.1111\/obr.13172"},{"key":"ref24","doi-asserted-by":"publisher","DOI":"10.1542\/peds.2022-060640"}],"container-title":["Obesity Facts"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/ofa\/adzag010","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,10,16]],"date-time":"2026-10-16T16:01:37Z","timestamp":1792166497000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/ofa\/adzag010"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,9,8]]},"references-count":24,"URL":"https:\/\/doi.org\/10.1159\/ofa\/adzag010","archive":["Portico"],"relation":{"is-supplemented-by":[{"id-type":"doi","id":"10.6084\/m9.figshare.33403444","asserted-by":"subject"}]},"ISSN":["1662-4025","1662-4033"],"issn-type":[{"value":"1662-4025","type":"print"},{"value":"1662-4033","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,9,8]]}}}
