CR is standard care for individuals who have experienced a cardiac event, but the current practice of predominantly aerobic exercise, a lower-fat diet and weight loss poorly addresses the issue of sarcopoenia. HPD, especially when combined with resistance exercise (RE), may be valuable adjuncts to current CR practice and benefit both muscle and cardiovascular health. Meta-analyses and randomised controlled trials of HPD and CVD risk show beneficial but variable effects regarding weight loss, the lipid profile, insulin resistance and lean body mass in those living with or high risk of CVD. Meta-analyses of prospective cohort studies on hard CVD endpoints favour lower- and plant-protein diets over higher animal protein, but the evidence is inconsistent. HPD augment the strength and muscle gaining benefits of RE in older populations, but there are no published data in those living with CVD providing promising opportunities for CR research. HPD raise concern regarding renal and bone health, the microbiome, branched chain amino acids and environmental sustainability and findings suggest that plant-based HPD may confer ecological and overall health advantages compared to animal-based HPD. However, incorporating RE with HPD might alleviate certain health risks. In conclusion, a largely plant-based HPD is deemed favourable for CR when combined with RE, but further research regarding efficacy and safety in CR populations is needed.<\/jats:p>","DOI":"10.1017\/s0029665123004779","type":"journal-article","created":{"date-parts":[[2023,10,25]],"date-time":"2023-10-25T09:51:20Z","timestamp":1698227480000},"page":"75-86","update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":2,"title":["Exploring high-protein diets in the context of cardiac rehabilitation"],"prefix":"10.1017","volume":"84","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3722-8466","authenticated-orcid":false,"given":"Ian G.","family":"Davies","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2023,10,25]]},"reference":[{"key":"S0029665123004779_ref75","doi-asserted-by":"publisher","DOI":"10.3389\/fnut.2023.1043391"},{"key":"S0029665123004779_ref94","doi-asserted-by":"publisher","DOI":"10.1016\/j.tjnut.2022.10.016"},{"key":"S0029665123004779_ref99","doi-asserted-by":"publisher","DOI":"10.1016\/j.foodres.2022.112131"},{"key":"S0029665123004779_ref101","doi-asserted-by":"publisher","DOI":"10.1016\/bs.afnr.2022.04.005"},{"key":"S0029665123004779_ref29","doi-asserted-by":"publisher","DOI":"10.1097\/MOL.0000000000000039"},{"key":"S0029665123004779_ref56","doi-asserted-by":"publisher","DOI":"10.1038\/s41366-019-0396-y"},{"key":"S0029665123004779_ref90","doi-asserted-by":"publisher","DOI":"10.3390\/nu12082285"},{"key":"S0029665123004779_ref96","doi-asserted-by":"publisher","DOI":"10.3389\/fnut.2022.977986"},{"key":"S0029665123004779_ref46","doi-asserted-by":"publisher","DOI":"10.3390\/nu13124380"},{"key":"S0029665123004779_ref104","doi-asserted-by":"publisher","DOI":"10.3390\/nu10050623"},{"key":"S0029665123004779_ref86","doi-asserted-by":"publisher","DOI":"10.2337\/dc19-0134"},{"key":"S0029665123004779_ref79","doi-asserted-by":"publisher","DOI":"10.1016\/j.csbj.2019.07.005"},{"key":"S0029665123004779_ref18","unstructured":"18.
