After the 2\u2010week sFR period ended, both groups received normal chow ad libitum for 3\u00a0months. Within 2\u00a0weeks after refeeding was initiated in the sFR group, body weight was restored to control levels; however, plasma angiotensinogen (1.3\u2010fold;\n              <jats:italic>P<\/jats:italic>\n              &lt;0.05), Ang\u2010[1\u20108] (2.0\u2010fold;\n              <jats:italic>P<\/jats:italic>\n              &lt;0.05), and angiotensin\u2010converting enzyme activity (1.1\u2010fold;\n              <jats:italic>P<\/jats:italic>\n              &lt;0.01) were all elevated 3\u00a0months after refeeding.

These findings may have implications for women who voluntarily or involuntarily experience an extended period of sFR and thus may be at increased risk of developing cardiovascular disease through sensitization of the renin\u2010angiotensin system even though their body weight, mean arterial pressure, and heart rate appear normal.<\/jats:p>\n          <\/jats:sec>","DOI":"10.1161\/jaha.120.017246","type":"journal-article","created":{"date-parts":[[2020,7,17]],"date-time":"2020-07-17T08:57:31Z","timestamp":1594976251000},"update-policy":"https:\/\/doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":4,"title":["Persistent Renin\u2010Angiotensin System Sensitization Months After Body Weight Recovery From Severe Food Restriction in Female Fischer Rats"],"prefix":"10.1161","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7031-2523","authenticated-orcid":false,"given":"Aline M.
