The response of serum leptin to short (4 days) and prolonged (28 days) energy restriction (50 % reduction in energy intake) was determined in 18 (9 male, 9 female) moderately obese humans (body mass index 32.0 ± 0.6 kg/m2 mean ± SEM), 9 of whom had mild non-insulin-dependent diabetes mellitus (NIDDM). Body composition was assessed before and at the end of(More)
The US Food and Drug Administration (FDA) recently approved lorcaserin and the combination of phentermine and extended release topiramate (phentermine/topiramate ER) for the treatment of obesity in conjunction with a lifestyle intervention, expanding the therapeutic options for long-term obesity pharmacotherapy, which was previously limited to orlistat.(More)
OBJECTIVE The risk of cardiovascular disease in type 2 diabetes is greater than is accounted for by conventional risk factors. We investigated whether energy restriction or modest fat loss improved the lipid profile in obese subjects with and without type 2 diabetes. The relationship of site of adipose tissue loss to lipid changes was also examined. (More)
Changes in the quality and quantity of carbohydrate foods may compromise nutrient intake in women with gestational diabetes mellitus (GDM). We hypothesized that glycemic index, glycemic load (GL), carbohydrate intake, grains, and cereal product consumption would be associated with nutrient adequacy. Eighty-two women with GDM (61% of Asian background, 34%(More)
BACKGROUND Previously published research that examined the effects of high egg consumption in people with type 2 diabetes (T2D) produced conflicting results leading to recommendations to limit egg intake. However, people with T2D may benefit from egg consumption because eggs are a nutritious and convenient way of improving protein and micronutrient contents(More)
OBJECTIVE To examine the mechanisms by which weight loss improves glycemic control in overweight subjects with NIDDM, particularly the relationships between energy restriction, improvement in insulin sensitivity, and regional and overall adipose tissue loss. RESEARCH DESIGN AND METHODS Hyperinsulinemic glucose clamps were performed in 20 subjects (BMI =(More)
OBJECTIVE The prevalence of gestational diabetes mellitus (GDM) is rising. There is little evidence to demonstrate the effectiveness of one dietary therapy over another. We aimed to investigate the effect of a low-glycemic index (LGI) versus a conventional high-fiber diet on pregnancy outcomes, neonatal anthropometry, and maternal metabolic profile in GDM.(More)
Background/Aim. Dietary glycemic index (GI) has received considerable research interest over the past 25 years although its application to pregnancy outcomes is more recent. This paper critically evaluates the current evidence regarding the effect of dietary GI on maternal and fetal nutrition. Methods. A systematic literature search using MEDLINE, EMBASE,(More)
Very-low-energy diets (VLEDs) and ketogenic low-carbohydrate diets (KLCDs) are two dietary strategies that have been associated with a suppression of appetite. However, the results of clinical trials investigating the effect of ketogenic diets on appetite are inconsistent. To evaluate quantitatively the effect of ketogenic diets on subjective appetite(More)
Distribution as well as amount of fat has health implications; central abdominal fat seems to be the major contributor to insulin resistance and risk of diabetes, hypertension and cardiovascular disease. Physical activity and diet affect overall adiposity; moreover, exercise specifically reduces visceral fat. The sexes differ in fat distribution; in(More)
