Effect of Food on Stress-Related Mood and Eating Behavior
Ever foundyourself munching furiously when stressed out, even if you are not hungry? Well, researchers havefound that stress leads to excessive eating especially of sweets and high-fatfoods and is one of the causes of obesity. 

 Some studies however indicate that eating excesscarbohydrates may actually increase the amount of stress. Stress and a highcarbohydrate diet together may increase the chances of obesity.

 The feeling of being rewarded by food is perceivedby the brain in two forms, 'liking' and 'wanting.' 'Liking' refers to thepleasure derived through the oro-sensory stimulation of food. 'Wanting' on theother hand, refers to the appetite, craving or motivation to obtain the food.

 A study was conducted on 19 men and 19 women to testthe effect of two different types of food, high protein or high carbohydrate onstress-induced changes in mood, the perception of 'liking' or 'wanting' by thebrain and post-meal energy intake.

 The participants of the study were examined on 4occasions. On one occasion, they underwent a stress session (by taking astress-causing computer exam) and were then given a high-protein diet. Inanother session, they received stress session with a high-carbohydrate diet. Inthe remaining two sessions, they received a high-protein or a high-carbohydratediet at rest without any stress.

 Pre- and post-meal 'liking' and 'wanting' weretested using a computer test. Appetite profile was measured with visualanalogue scales, mood changes were measured with the help of questionnaires andpost-meal energy intakes were measured.

 The participants were found to be depressed oranxious during stress. The high-protein intake, when compared tohigh-carbohydrate intake, reduced subsequent 'wanting' and energy intake atrest only in patients with high disinhibited eating behavior (Disinhibitedeating behavior is when a person eats too quickly and is repeatedlyunsuccessful during dieting). However, this effect disappeared during stress. In all other cases, the two diets hadsimilar effects on stress-related mood and eating behavior.

Thus, theeffect of diet on stress-related eating behavior is the same irrespective ofthe type of food, according to this study.
