OBJECTIVE To examine the effects of dietary protein and obesity classification on energy-restriction-induced changes in weight, body composition, appetite, mood, and cardiovascular and kidney health. RESEARCH METHODS AND PROCEDURES Forty-six women, ages 28 to 80, BMI 26 to 37 kg/m(2), followed a 12-week 750-kcal/d energy-deficit diet containing higher(More)
The regular performance of resistance exercises and the habitual ingestion of adequate amounts of dietary protein from high-quality sources are two important ways for older persons to slow the progression of and treat sarcopenia, the age-related loss of skeletal muscle mass and function. Resistance training can help older people gain muscle strength,(More)
Appetite and meal energy intake (MEI) following aerobic (AEx) and resistance (REx) exercises were evaluated in 19 young, active adults. The participants completed duplicate 35-min sessions of AEx, REx, and sedentary control, and consumed an ad libitum pasta meal 30 min postsession. Hunger transiently decreased after AEx but was not influenced by REx. MEI(More)
Recent findings support a role for ghrelin in the regulation of energy homeostasis and possibly reproductive function. The primary purpose of this study was to test whether differences in fasting ghrelin levels exist in exercising women with differing menstrual and metabolic status. Menstrual cycle status was defined as sedentary ovulatory (SedOvul; n = 10,(More)
PURPOSE Elevated postprandial glycemic (PPG) excursions are significant risk factors for cardiovascular disease in type 2 diabetes patients. In this study, we tested if and for how many meals a single bout of exercise would reduce PPG responses to subsequent meals in type 2 diabetes (T2D) patients using a continuous glucose monitor system (CGMS). METHODS(More)
The effects of an enzyme-hydrolyzed arabinoxylan from wheat (AXOS) versus an intact arabinoxylan from flax (FLAX) added to a ready-to-eat cereal (RTEC) on the postprandial appetitive, hormonal, and metabolic responses in overweight women (BMI 25.0-29.9 kg/m2) were evaluated. Subsequent meal energy intake was also assessed. Two randomized, double-blind,(More)
Ghrelin is directly involved with short-term regulation of energy balance. Although circulating levels of ghrelin are elevated in anorexia nervosa and reduced in obesity, the role of ghrelin in regulating long-term energy balance in healthy women has not been investigated. We examined the effects of a 3-month energy deficit-imposing diet and exercise(More)
OBJECTIVE The purpose of this study was to determine whether chronic energy deficiency achieved with caloric restriction combined with exercise is associated with changes in the 24-hour profile of ghrelin in non-obese, pre-menopausal women. RESEARCH METHODS AND PROCEDURES Twelve non-obese (BMI = 18 to 25 kg/m(2)), non-exercising women (age, 18 to 24(More)
BACKGROUND Breakfast skipping is a common dietary habit practiced among adolescents and is strongly associated with obesity. OBJECTIVE The objective was to examine whether a high-protein (HP) compared with a normal-protein (NP) breakfast leads to daily improvements in appetite, satiety, food motivation and reward, and evening snacking in overweight or(More)
OBJECTIVE This study assessed the effectiveness of a prescribed weight-loss diet with 0.8 versus 1.4 g protein·kg(-1) day(-1) on changes in weight, body composition, indices of metabolic syndrome, and resting energy expenditure (REE) in overweight and obese men. DESIGN AND METHODS Men were randomized to groups that consumed diets containing 750 kcal(More)
