How sweet or savory diets effect future food choices and fullness

Following either a sweet or savory diet can be difficult to maintain as following either one leads to a desire for the other. So by attempting to control intake so rigidly it can backfire leading you to crave what you might have been trying to avoid to begin with.

The objective of this study was to investigate the effect of taste of a 24-h diet on subsequent food preferences (food choice and intake of specific food categories) and satiety. We used a crossover design, consisting of a 24-h fully controlled dietary intervention, during which 39 healthy subjects consumed diets that were predominantly sweet tasting, savory tasting, or a mixture. The diets were similar in energy content, macronutrient composition, and number of different products used. Following the intervention an ad libitumlunch buffet was offered the next day, consisting of food items differing in taste (sweet/savory) and protein content (low/high) and intake was measured. The results showed that the taste of the diet significantly altered preference for food according to their taste properties (p < 0.0001); after the savory diet, intake of sweet foods was higher than of savory foods. After the sweet diet, savory foods tended to be preferred (p = 0.07). No interaction was seen between the taste of the diet and food preference according to their protein content (p = 0.67). No differences in total energy intake (kJ) at the ad libitum lunch buffet were observed (p = 0.58). It appears that in healthy subjects, taste of a 24-h diet largely affects subsequent food preferences in terms of sensory appetite, whereby savory taste exerts the strongest modulating effect. Taste of a 24-h diet has no effect on macronutrient appetite.
