Common diet durations.

Duration	Key findings	References#
12 weeks	Identified diabetic symptoms in wild type C57BL/6 mice: these were not found in the wild type MRL mice.	[12]
	Identified diabetic cardiomyopathy symptoms in wild type C57BL/6 mice: these were not found in the wild type MRL cardiac tissue.	[16]
	Identified sulforaphane (an antioxidant) decreases diabetic cardiomyopathy in a HFD plus streptozotocin model.	[54]
16 weeks	In WT C57BL/6 HFD increased LVW by 21%. In WT C57BL/6 HFD increased liver weight by 86%.	[55]
12-, 16-, and 20-week comparisons	Epididymal AT death peaks at 16 weeks of HFD, compared to 12 and 20 weeks. This is coincident with a peak of AT macrophages. Inguinal AT death was less pronounced at all times tested.	[56]
24 weeks	Identified that a Th1 immune response caused mice to be more susceptible to HFD pathologies.	[48]
8-, 12-, and 16-month comparisons	At 8 months hyperglycemia, hyperinsulinemia, and hypercholesterolemia and insulin resistance were found. Cardiac remodeling by echo was also identified. At 16 months the authors also report cardiac metabolic compensations and tissue remodeling in the form of fibrosis and hypertrophy.	[18]
8-, 30-, and 60-week comparisons	NAFLD and HCC established at 30 weeks and significant liver pathology observed at 8 weeks of HFD.	[21, 57]
6 and 16 weeks	Identified liver pathology only at 16 weeks and only in males.	[58]
6 weeks	Increased LV mass and reduced FS.	[59]

AT, adipose tissue; FS, fractional shortening; HCC, hepatocellular carcinoma; LV, left ventricle; NAFLD, nonalcoholic fatty liver disease. ^#References are given where inappropriate.
