*2.4. Episodic Intake of Individually Presented GM- and CM-Enriched Chow in Sated Adult Mice and Rats*

Rats and mice were given episodic access to the chow enriched with GM or CM according to the protocol described above, where, instead of GM or CM, a GM- or CM-enriched chow (see Table 2 for composition of GM and CM chow) was presented for 2 h (10:00). Standard chow pellets were removed during this 2-h meal, but water was left in the cages. Intake of chow pellets (at room temperature) was measured using a digital scale after 2 h and expressed in grams per gram of body weight. In order to assess baseline intake, a control group of animals had a fresh batch of the standard chow placed in the hopper for 2 h (*n* = 7–8/group for both mice and rats). This feeding experiment was conducted in a separate cohort of animals.

**Table 2.** *Cont.*

Rats and mice previously exposed to GM- and CM-enriched chow (pre-exposure to both chow types was simultaneous) were deprived of standard chow overnight (food taken away at 16:00). On the next day (10:00), animals received either standard chow, GM- or CM-enriched pellets (mice: *n* = 7–8/group; rats: *n* = 8–9/group) at room temperature. Intakes were measured using a digital scale after 2 h and expressed in grams per gram of body weight. This feeding experiment was conducted in a separate cohort of animals.
