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)
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)
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)
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)
BACKGROUND Although protein-rich plant foods have recently been touted as an equivalent to animal products, limited data exist regarding the effects of animal vs. plant proteins on appetite, satiety, and subsequent food intake. OBJECTIVE The objective was to determine whether a high-protein beef lunch alters the appetitive, hormonal, and neural signals(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)
BACKGROUND Breakfast skipping (BS) is closely associated with overeating (in the evening), weight gain and obesity. It is unclear whether the addition of breakfast, with emphasis on dietary protein, leads to better appetite and energy intake regulation in adolescents. OBJECTIVE The purpose of the study was to examine the impact of addition of a(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)
