SO, sham-operated mice; LO, mice containing implants corresponding to 2% of body mass; HI, mice containing implants corresponding to 10% of body mass; M,males; F, females.

Values for resting energy expenditure ERE (kJ d-1) are means of the 10 lowest values for total daily energy expenditure, measured using indirect calorimetry over a 48 h period. ERE (%) was expressed relative to mean ERE of basal measurement (-2 weeks).

+2, 2 weeks after weight load; +12, 12 weeks after weight load.

Values are means ± s.e.m.; number of measured animals is given in parentheses.

Differences were tested using two-way repeated-measures ANOVA (factors:gender, group)
