Methods: We investigated this process comparing two different high-fat dietary approaches to induce obesity, in which all rats received about 40% of their energy intake as lipids. The main
nutrient difference between the diets, when compared with controls fed standard lab chow, was the lipid content. Cafeteria diets (K) were devised to be tasty, and thus highly desirable to the rats, mainly for its diverse mix of tastes, particularly salty and sweet. This diet was compared with another high-fat (HF) potentially obesogenic diet, devised not to be as tasty as K, and prepared just supplementing standard chow pellets with fat. We also analysed the influence of sex on the effects of the diets.
Results: K rats grew faster, especially the males, although females showed a higher proportion
of body lipid, because of a high lipid, sugar and protein intake. HF weight change rates were
not different from those of controls. In addition to high sugar, K rats also ingested large
amounts of salt. With this study we have shown that the key factor eliciting the excess energy
intake in a high-energy diet rat model was not solely or mainly their fat intake. The changes in
body fat accrual were more a consequence of their appetence for the food.
Conclusions: The results show that the significant presence of sugar and salt is a powerful
factor promoting excess food intake, more effective than increasing diet lipid content. These
effects were already observed after a relatively short treatment, additionally confirming the
differential effects of sex on the hedonic and obesogenic response to diet.

MRI DATA
All participants were examined on a 3T MRI scanner (Magnetom Trio Tim,
Siemens Medical Systems, Germany) at the Centre de Diagnòstic per la Imatge
in the Hospital Clínic of Barcelona. High-resolution T1-weighted images were
acquired with the MPRAGE 3D protocol (TR=2300 ms; TE=3 ms; TI=900 ms;
FOV=244x244 mm2; 1 mm isotropic voxel).

Cortical thickness data
The cortical thickness matrices are:
- rawCT_GG: data for the gifted group; contains the cortical thickness of the
308 regions (columns) for each individual subject (raws) in mm
- rawCT_CG: data for the control group; contains the cortical thickness of the
308 regions (columns) for each individual subject (raws) in mm
