The scheme of dietary treatments of females during pregnancy and lactation periods with their numbers (n) in successively selected groups. Maternal blood parameters, body mass and food intake were measured on the day of fertilization (G0), on gestational days 4, 15, 20 and on the second day postpartum (PP2). On PP2, in six previously KD-fed females, the normal diet was introduced. In addition, on PP2, six ND- and six KD-fed females were subjected to perfusion-fixation and their brain processed for FTIR analysis. Neurodevelopmental reflex tests on pups were performed during the lactation period, i.e., up till day 21 postpartum (PP21). Abbreviations: ND, KD, females on normal and ketogenic diet, respectively, KDND, females initially fed with KD, which on PP2 was replaced with ND. Periods of ND and KD application are indicated in green or yellow, respectively
