Weight-losing patients with advanced cancer often fail to gain weight with conventional nutritional support. This suboptimal response might be explained, in part, by an increased metabolic response to feeding. It has been suggested that eicosapentaenoic acid (EPA) can modify beneficially the metabolic response to cancer. The aim of the present study was to examine the metabolic response to feed...

These studies were done to examine the effects of body composition, resting energy expenditure (REE), sex, and fitness on basal and insulin-regulated FFA and glucose metabolism. We performed 137 experiments in 101 nondiabetic, premenopausal women and men, ranging from low normal weight to class III obese (BMI 18.0-40.5 kg/m2). Glucose flux was measured using [6-(2)H2]glucose and FFA kinetics wi...

PURPOSE The purpose of this study was to investigate the effectiveness of a composite weight-loss dietary supplement on body composition and blood lipid changes in middle-aged women. METHODS Thirty seven middle-aged women living in the Kyunggi area participated in this study and they were randomly divided into 2 groups (Dietary supplement ingestion group; DG, n = 20 and Placebo group; PG, n =...

An experiment was conducted in order to study the effect of 3 levels of fat (1, 3, 5%), and 2 levels of L-carnitine (0, 250 mg/kg) on 360 male Ross broiler chicks in a factorial arrangement (2×3) with completely randomized design with 6 treatments, 4 replicates, and 15 chicks in each replicates. All diets were isocaloric and isonitrogenous and were fed to chicks from 1 to 42 days of ages. Durin...

Carcass analysis data show that weanling rats fed high-fat (HF) and low-fat (LF) diets until the day of first estrus had similar body compositions at estrus, although the HF rats had estrus significantly earlier and at a lighter body weight (P less than 0.01) than the LF-diet rats. Total water as percent of wet weight, protein as percent of wet weight, and the water/protein ratios of the HF- an...

Two objectives of this study were to investigate the weekly change in plasma L-carnitine concentration during the 28 day suckling period and to determine the relative mRNA expression level of a L-carnitine transporter, OCTN2, in porcine mammary tissue at early and peak lactation. The results showed that the L-carnitine concentration of piglets after giving birth was 3.94±0.13 mg/L. L-carnitine ...

BACKGROUND To contribute to the current debate as to the relative influences of dietary intake and physical activity on the development of adiposity in community-based children. METHODS Participants were 734 boys and girls measured at age 8, 10 and 12 years for percent body fat (dual emission x-ray absorptiometry), physical activity (pedometers, accelerometers); and dietary intake (1 and 2-da...

The purpose of this study was to evaluate the effects of repeated fasting and refeeding on lipid metabolism. Thirty male ICR mice, aged 6 weeks, were fed an AIN-93 control diet during the experimental period. The mice were divided into 5 groups: Non fasting group (ad libitum-fed, NF), fasting for 3 days (F), fasting for 3 days and then refeeding for 4 days repeated once (FRF1), fasting for 3 da...
