BACKGROUND Beverages are contributing an increased proportion of energy to the diet. Because they elicit a weak compensatory dietary response, they may increase risk of positive energy balance. OBJECTIVES This study aimed to document the differential effects of matched liquid and solid carbohydrate loads on diet and body weight. DESIGN In a cross-over(More)
OBJECTIVE To investigate the effects of chronic peanut consumption on energy balance and hedonics. DESIGN Thirty-week, cross-over, intervention study. Participants were provided 2113+/-494 kJ/day (505+/-118 kcal/day) as peanuts for 8 weeks with no dietary guidance (free feeding-FF), 3 weeks with instructions to add peanuts to their customary diet(More)
In an attempt to better characterize the subjective experience of hunger, we assessed the locus and extent of sensations associated with varying degrees of hunger. In the first study, 83 subjects indicated by marking on a drawing of a human figure where they felt hungry under hypothetical conditions of slight to extreme hunger. Approximately 55% of subjects(More)
Dietary compensation for energy provided as ethanol is reportedly limited. Whether this is a function of the ethanol or other aspect of the medium in which it is ingested is not known. Eight male and eight female adults ingested 1.08 liters of beer (5.0% ethanol w/v, 1891kJ), light beer (2.9% ethanol w/v, 1197kJ), no-alcohol beer (0.1% ethanol w/v, 816kJ),(More)

Accumulating evidence indicates that the taste of salt is innately appealing to humans, although responses to salty foods are strongly influenced by environmental factors. Except in instances of severe, prolonged sodium depletion, a sodium-specific appetite has not been documented in humans. Limited data reveal no clear association between early exposure to(More)
Accumulating evidence suggests dietary fatty acids (FAs) may be sensed in the oral cavity. However, the effective cues have not been characterized. In particular, influences from other sensory cues have hampered identification of an independent gustatory contribution. Experiment 1 examined techniques to minimize the formation of FA oxidation products and(More)
(-)-Hydroxycitric acid (HCA) reportedly promotes weight loss, in part, through suppression of hunger. However, this mechanism has never been evaluated in humans in a controlled study. Eighty-nine mildly overweight females were prescribed 5020-kJ diets for 12 weeks as part of a double-blind, placebo-controlled parallel group study. Forty-two participants(More)
Oral exposure to dietary fat (through modified sham feeding, which entails mastication and expectoration of foods) augments the postprandial triacylglycerol (TAG) concentration, in part, though augmented lipid absorption. This study was designed to characterize early events in this process. At 2200 h, 25 healthy adults (13 men, 12 women) consumed 80 g of(More)
Oral exposure to dietary fat results in an early initial spike, followed by a prolonged elevation, of serum triglycerides in humans. The physiological and pathophysiological implications remain unknown. This study sought to determine the incidence of the effect, the required fat exposure duration, and its reliability. Thirty-four healthy adults participated(More)

Accumulating evidence indicates that oronasal sensory stimulation influences nutrient metabolism. This work examined the effects of oral exposure to dietary fat on postprandial plasma triacylglycerol (triglyceride) concentrations. Fifteen (six male, nine female) healthy adults were exposed to each of four treatments presented in random order. After(More)
