Green tea may stimulate energy metabolism; however, it is unclear if acute effects are caused by specific catechins, caffeine or their combination. The objective of the present study was to examine the separate and combined effects of different catechins and caffeine on energy expenditure (EE) and fat oxidation over a single day. Fifteen healthy,(More)
BACKGROUND Appetite measures are often recorded by visual analogue scales (VAS), and are assumed to reflect central nervous system (CNS) perceptions and sensations. However, little is known about how physiological, psychological, social, and cultural factors influence VAS. OBJECTIVE To investigate whether age, gender, body mass index (BMI), smoking(More)
Peptide YY (PYY)(3-36) has been shown to produce dramatic reductions in energy intake (EI), but no human data exist regarding energy expenditure (EE), glucose and fat metabolism. Nothing is known regarding PYY1-36. To compare effects of PYY(1-36) and PYY(3-36) on appetite, EI, EE, insulin, glucose and free fatty acids (FFA) concentrations, 12 lean and 12(More)
BACKGROUND Video game playing has been linked to obesity in many observational studies. However, the influence of this sedentary activity on food intake is unknown. OBJECTIVE The objective was to examine the acute effects of sedentary video game play on various components of energy balance. DESIGN With the use of a randomized crossover design, 22(More)
Our aim was to examine the effects of GLP-1 and PYY3-36, separately and in combination, on energy intake, energy expenditure, appetite sensations, glucose and fat metabolism, ghrelin, and vital signs in healthy overweight men. Twenty-five healthy male subjects participated in this randomized, double-blinded, placebo-controlled, four-arm crossover study (BMI(More)
BACKGROUND The reproducibility of the measurement of ad libitum energy intake (EI) is not well known. Furthermore, it is not known whether standardized conditions before the test day influence this measure. OBJECTIVE The objective was to examine the reproducibility and power of the measurement of ad libitum EI with and without prior diet standardization.(More)
Many dietary factors or substances exert effects on the three components of energy balance, and one strategy for tackling weight gain could be to use the inherent properties of these substances. Here, we will review the evidence regarding nutritional factors with a potential impact on energy balance, such as wholegrain foods, dietary fiber and protein(More)
Foods and dietary patterns that enhance satiety may provide benefit to consumers. The aim of the present review was to describe, consider and evaluate research on potential benefits of enhanced satiety. The proposal that enhanced satiety could only benefit consumers by a direct effect on food intake should be rejected. Instead, it is proposed that there is(More)
BACKGROUND Thermic effect of a meal (TEF) has previously been suggested to influence appetite. OBJECTIVE The aim of this study was to assess whether there is an association between appetite and TEF. Second, to examine whether protein intake is associated with TEF or appetite. DESIGN Individual participant data (IPD) meta-analysis on studies were(More)
It is unclear whether postprandial blood glucose or insulin exerts a regulatory function in short-term appetite regulation in humans. The aim of this study was to investigate, by use of meta-analysis, the role of blood glucose and insulin in short-term appetite sensation and energy intake (EI) in normal weight and overweight participants. Data from seven(More)
