It seems like everyone wants to figure out how to eat less. Some studies indicate that chewing more might help. But if you don't have extra time to spend on mastication, you might want to read this study. Apparently, at least when eating a multi-course banquet of meatballs (M), french fries (F), brownies (B), and vanilla cream (C), the order in which you eat your chosen delicacies may influence the total amount you consume. So if you want to eat less dessert, try meatballs, then french fries, then meatballs, then french fries, then meatballs, then french fries, then vanilla cream, then brownies, then vanilla cream, then brownies, then vanilla cream. BEST DIET EVVAAARRRR! (Caveat: this will make you eat more french fries).

Alternation between foods within a meal. Influence on satiation and consumption in humans. "Food habituation/dishabituation has been observed in non-human primates in neurophysiological investigations of feeding, and in humans, through salivation or hedonic responses to food. The objective of the study was to evaluate in humans the effect of disruption of habituation by alternation between foods in a meal. Sixteen volunteers (8 males, 8 females; age: 21+/-1 yr; BMI: 21.5+/-0.5 kgm(-2)) ate a two-course meal [meatballs (M) and fries (F), then vanilla cream (C) and brownies (B)] during three randomized sessions. Sessions differed by the alternation of these foods: No-Repetition session with M-F-C-B; Single-Repetition session with F-M-F-B-C-B; Multiple-Repetition session with M-F-M-F-M-F-C-B-C-B-C-B. Final intakes of F and B were ad libitum. Quantities consumed (g, kJ) and ratings of hunger, pleasantness and desire to eat each food were evaluated. Compared to the No-Repetition session, subjects ate 18% more fries and 16% more brownies in the Single-Repetition, and 13% more fries but 20% less brownies in the Multiple-Repetition session. Pleasantness for the food decreased from before to after intake for both fries and brownies with no significant difference between the sessions. It therefore appears that moderate alternation between foods at lunch increases intake, but multiple alternations of foods at the end of the meal may decrease consumption. These differences in intakes could result from differences in sensory-specific satiety via disruption of habituation."
