Introduction:

changes in dietary/energetic composition during the critical period of development (pregnancy/lactation) or even during mealtimes may contribute to changes in metabolic and behavioral parameters such as feeding behavior.

Objective:

the study aimed to examine the repercussions of time-restricted feeding on feeding behavior and on some parameters of glycemic and lipemic metabolism of the offspring of adult rats whose mothers were fed a westernized diet during pregnancy and lactation.

Methods:

initially, 43 male Wistar rats were used. At 60 days of life, the rats were divided into 4 groups: C: control group; RC: control group with time-restricted feeding; W: westernized diet during pregnancy/lactation group; RW: westernized diet group during pregnancy/lactation group with time-restricted feeding. The following parameters were evaluated: behavioral sequence of satiety (BSS), biochemical parameters, and abdominal fat.

Results:

findings highlighted a high level of abdominal fat in the groups whose mothers were submitted to a westernized diet, as well as hypertriglyceridemia, and clear differences in feed rate and meal length. This study showed that the westernized diet ingested by mothers during pregnancy and lactation induced hyperlipidemia and changes in the feeding behavior of their adult offspring.

Conclusions:

these changes may be responsible for eating disorders and risk factors for metabolism disturbance-related diseases.
