Lipolysis, μmol/(kg · min)	24.1 ± 9.22	22.3 ± 17.92				10.9 ± 3.63

¹Values are means ± SEMs. *Changes across the fast, P < 0.05. Data were compiled from references 25, 26, 27, 32, 36 and D. Crocker, unpublished data. Lipolysis data are from reference 25. NEFA, nonesterified fatty acid; NES, northern elephant seal.
