In a small lab experiment, it was found that obese women showed imprecise learning when the reward was food, not when the reward was money. As many as 135 obese and normal weight men and women were tested on how good they were at predicting when they would see a food or money reward.

Ifat Levy, Assistant Professor of comparative medicine and neurobiology at Yale University, asserted, "It is possible that once food is in the environment, obese individuals have a hard time ignoring its distracting properties".

In one study, it was found that overweight women showed a preference for quick reward as compared to normal-weight women. On the other hand, another study explains that obese women were not capable enough to block out their craving to eat when enthused by food.

Also, there are some of the areas which involved impaired learning of fat women. They are: sex differences in body images between men and women, hormones and differences in the function of prefrontal brain. With this, it is quite clear that women deal with diverse body-image issues as compared to men.

No matterwhat the findings are, it only points towards the improved treatments for obesity. Whatever the men or women eat, all have to do a lot with social aspects and cues. So, one has to think before putting the food into stomach.
