Mice were fed a high fat-diet with indicated treatments for 6 weeks. Visceral fat volume and muscle palmitate uptake was determined via PET/CT. RER and heat production was calculated from 24 h oxygen consumption measurements in metabolic chambers. Data are presented as means ± SE (n = 5 to 10). Non-matching letter superscripts in each row denote significant differences at the indicated p-value.
1Low resveratrol: 12.5 mg resveratrol/kg diet.
2High resveratrol: 225 mg resveratrol/kg diet.
3Low HMB: 2 g hyroxymethylbutyrate (calcium salt).
4High HMB: 10 g hyroxymethylbutyrate (calcium salt).
5Leucine: 24 g leucine/kg diet.
