Rodent models associated with the development of binge-eating like behaviors.

Model	Species	Procedure	Eating Outcome	Obesity outcome	Reference
Sham feeding	Rat	Animals are fitted with chronic fistulas to drain liquid food before entering the gastrointestin al tract	Hyperphagia in brief periods of time	No body weight gain	Smith et al. 1989
Restriction/Refeedi ng	Rat	access to palatable diet is followed by food deprivation cycle	Rebound hyperphagia of highly palatable food upon refeeding	No body weight gain	Hagan and Moss, 1996
Tail pinch	Rat	Pinching a rat’s tail while measuring the rat’s food intake	Increased intake during tail pinching and shortly afterwards	No body weight gain	Rowland and Antelman, 1976
Shock stress	Rat	Measurement of food intake after application of an acute 0.6 mA electric shock.	Increased daily consumption of high palatable diet when associated with food restriction	No body weight gain	Hagan et al. 2002
Limited access	Rat/mous e	Limited availability of optional source of dietary fat under non- food-deprived conditions.	Increased high sucrose/fat/mix ed diet at onset of access, and larger fewer sugary meals throughout the access period	Body weight gain/ No body weight gain	Avena et al. 2009; King et al., 2016; Wojnicki et al. 2008.
Visible burrow system	Rat	Single housing after 2 weeks exposure to subordination	Hyperphagia from longer meals with longer inter- meal intervals	Body weight gain	Melhorn et al. 2010
		in mixed-sex colonies	occurring in the recovery post- stress phase
Chronic social defeat	Mouse	Single housing after 10 days subordination and protected co-housing with 10 different aggressor mice.	Increased daily food intake, unknown meal pattern occurring in the recovery post- stress phase	Body weight gain	Lutter et al. 2008
Chronic psychosocial stress	Mouse	4 weeks subordination and protected co-housing with the same aggressor mouse.	Hyperphagia from higher consumption rate and reduced satiety intervals	Body weight gain	Razzoli et al. 2015
