- Hypothesis 1: (a) Ls and Lm will have independent and interactive effects on food intake and EE. Intake at an ad libitum test meal and during a 24 h period, measured after 3 d of each intervention, will be greater during Ls and Lm, and this will be enhanced when Ls and Lm are combined, compared to Ns and Nm. (b) Resting metabolic rate (RMR) will be lower during the Ls and Lm phases, and this will be further reduced when Ls and Lm are combined compared to the Ns and Nm phases (Ns/Nm<Ls/Nm≤Ns/Lm<Ls/Lm).
