Meal Microstructure Characterization from Sensor-Based Food Intake Detection

Meal Microstructure Characterization from Sensor-Based Food Intake Detection

To avoid the pitfalls of self-reported dietary intake, wearable sensors can be used. Many food ingestion sensors offer the ability to automatically detect food intake using time resolutions that range from 23 ms to 8 min. There is no defined standard time resolution to accurately measure ingestive behavior or a meal microstructure. This paper aims to estimate the time resolution needed to accur...

Towards automatic food intake monitoring using wearable sensor-based systems

Pre-meal anxiety and food intake in anorexia nervosa.

Anorexia nervosa (AN) is a serious mental illness characterized by reduced caloric intake that often persists after acute weight restoration. This preliminary study assesses the relationship between pre-meal anxiety and food intake in recently weight-restored individuals with AN. We hypothesized that pre-meal anxiety is inversely related to caloric intake in AN. Caloric intake and pre-meal anxi...

Variety in a meal enhances food intake in man.

Variety in a meal enhances food intake in man. PHYSIOL BEHAV.26(2) 215-221, 1981.-We find that in man satiety can be partly specific to foods eaten [12]. The possibility that this specificity of satiety leads to overeating if a wide variety of foods is readily available is tested here. The intakes of subjects offered a variety of foods in succession during a meal were compared to intakes when t...

[Food intake and meal patterns of adolescents, São Paulo, Brazil].

OBJECTIVE To assess food intake and meal patterns in adolescents, a cross-sectional study was conducted with 228 adolescents from a public school, SP, Brazil. METHODS Total energy, macronutrients, calcium, iron, and vitamin A intakes were evaluated. The food pattern was compared with the eating patterns established by the Food Pyramid for adolescents. Meal frequency was assessed to identify m...
