Despite the lack of international agreement regarding the definition and classification of fiber, there is established evidence on the role of dietary fibers in obesity and metabolic syndrome. Beta glucan (β-glucan) is a soluble fiber readily available from oat and barley grains that has been gaining interest due to its multiple functional and bioactive(More)
The objective was to compare the effects of ad libitum consumption of commonly consumed meal-time beverages on energy and fluid intakes and post-meal average subjective appetite and blood glucose in healthy adults. In a randomized controlled design, 29 males and females consumed to satiation an ad libitum pizza meal with one of five beverages in unlimited(More)
The objective was to compare the effects of pre-meal consumption of familiar beverages on appetite, food intake, and glycemic response in healthy young adults. Two short-term experiments compared the effect of consumption at 30 (experiment 1) or 120 min (experiment 2) before a pizza meal of isovolumetric amounts (500 mL) of water (0 kcal), soy beverage (200(More)
BACKGROUND & AIMS We aimed to compare the effects of protein to carbohydrate ratio and physical form in dairy on glucose homeostasis and food intake. METHODS In a crossover design, 20 healthy males consumed 250 g of one of five treatments, plain yogurt, plain yogurt with honey, strawberry yogurt, skim milk or orange juice, as mid-morning snacks. Food(More)
The acute relationship between substrate oxidation as measured by respiratory exchange ratio (RER) and food intake (FI) has not been defined. The purpose of the study was to determine acute relationships between RER, modified by exercise and a glucose load, and FI and net energy balance (NEB) in physically active normal-weight boys and men. In a crossover(More)
PURPOSE This study was conducted to investigate whether a higher proportion of protein or fat is more favorable for optimal ghrelin and peptide YY (PYY) release in subjects consuming low carbohydrate meals. METHODS Eight normal weight men received, on three separate occasions, high protein low fat (HPLF) (40% protein, 25% fat), low protein high fat (LPHF)(More)
AIMS The aim of this study was to investigate the appetite hormones and metabolic responses of hyperinsulinemic subjects to high-protein (HP) meals as compared to high-carbohydrate (HC) and high-fat (HF) meals. DESIGN Fifteen hyperinsulinemic normoglycemic men received, on 3 separate occasions, HP, HC, or HF meals in a randomized crossover design. Blood(More)
BACKGROUND/OBJECTIVES Sodium alginate reduces appetite and glycemia, when consumed in water- and sugar-based drinks. But, its effects when added to other commonly consumed beverages have not been reported. Because chocolate milk (CM) is criticized for raising blood glucose more than unflavored milk, the aim of our study was to investigate the effect of(More)
The effect of beverages commonly consumed by children in-between or with meals on short-term food intake (FI) and glycemic control has received little attention. Therefore, 2 experiments were conducted in 9- to 14-year-old children following a randomized repeated-measures design. Experiment 1 (n = 32) compared the effects of water (control) and isocaloric(More)
