Humans live, eat, and become overweight/obese in complex surroundings where there are many available food choices. Prenatal exposure to poorfood choices predisposes offspring to increased negative health risks, including obesity.

Many animal experiments have analyzed intergenerational body weight parameters in an 
environment without food choices, which may not be directly translatable to the human food environment.

In this study, offspring from mothers with a defined high-fat diet (HFD) or low-fat diet (LFD) were arbitrarily assigned to either an exclusively LFD or HFD or to a diet where they have a 
choice between LFD and HFD (choice diet).

Offspring displayed negative outcomes of increased body weight, body fat, serum leptin, and blood glucose levels when given the 
choice diet compared with offspring on the LFD.

Conversely, improved energy expenditure was found for offspring given the 
choice diet compared with offspring from HFD dams given LFD.

In addition, maternal diet-specific influences on offspring metabolic parameters were identified, especially in offspring from HFD dams, including positive outcomes of reduced leptin in LFD offspring, reduced corticosterone and cholesterol levels in HFD offspring, and increased exercise levels in 
choice offspring, as well as the negative outcome of increased calorie intake in LFD offspring from HFD dams.

This defined model can now be used as the basis for future studies to characterize the cycle of inter- and intragenerational obesity and whether more realistic diet environments, especially those including 
choice, can mitigate phenotype.
