BACKGROUND Nuts appear to have cardiovascular benefits but their effect in diabetic patients is unclear. OBJECTIVE The objective was to assess effects of almond-enriched diets on insulin sensitivity and lipids in patients with normoglycemia or type 2 diabetes. DESIGN Study 1 assessed the effect of almonds on insulin sensitivity in 20 free-living healthy(More)
OBJECTIVE This study assessed longitudinal changes in body composition, fat distribution and energy balance in perimenopausal women. We hypothesized that total fat and abdominal body fat would increase at menopause due to decreased energy expenditure (EE) and declining estrogen, respectively. DESIGN Observational, longitudinal study with annual(More)
Obesity is related to the risk for developing non-insulin-dependent diabetes mellitus (NIDDM), hypertension, and cardiovascular disease. Visceral adipose tissue (VAT) has been proposed to mediate these relationships. Abdominal subcutaneous adipose tissue (SAT) is divided into 2 layers by a fascia, the fascia superficialis. Little is known about the(More)
Previous studies have shown differences between African-American and Caucasian populations in the prevalence of obesity and obesity-related diseases such as type IIoffabetes. The purpose of this study was (1) to compare the insulin sensitivity index (SI) from the minimal model in 37 African-American and 22 Caucasian women matched for age and obesity, and(More)
OBJECTIVE To examine the obesity-related chronic diseases in the US adult population according to gender, race and socioeconomic status. METHODS Data from the 1994-1996 Continuing Survey of Food Intakes by Individuals (1994-1996 CSFII) conducted by the US Department of Agriculture/Agricultural Research Service (USDA/ARS) were used in the analysis.(More)
The Hundred Person Wellness Project (HPWP) is a 10-month pilot study of 100 'well' individuals where integrated data from whole-genome sequencing, gut microbiome, clinical laboratory tests and quantified self measures from each individual are used to provide actionable results for health coaching with the goal of optimizing wellness and minimizing disease.(More)
Dietary fat and its relation to obesity has been a controversial issue for several years. In this review, several kinds of data relating to this issue are presented. There are epidemiological cross-country data and data within countries showing an effect. However, in the United States, the intake of fat appears to be declining, whereas the prevalence of(More)
In experiment 1, 21 male Holstein calves (43.9 kg) were fed only milk replacer at 1.4% of their body weight as dry matter for 6 wk. Dietary treatments included a commercial milk replacer (22% protein, 15% fat) containing (dry basis) either 6.4% Ca propionate or 6.4% dextrose (control) and either 0 or 0.5 mg/kg of supplemental Cr as Cr propionate. Neither Cr(More)
OBJECTIVE This study tested a psychosocial model of binge eating symptoms in obese men and women. Predictor variables included depression, dietary restraint, self-esteem, weight cycling, history of teasing, body dissatisfaction, and neuroticism. METHOD Participants (N = 808) completed a packet of self-report questionnaires. RESULTS Weight cycling,(More)
Weight-loss interventions generally improve lipid profiles and reduce cardiovascular disease risk, but effects are variable and may depend on genetic factors. We performed a genetic association analysis of data from 2,993 participants in the Diabetes Prevention Program to test the hypotheses that a genetic risk score (GRS) based on deleterious alleles at 32(More)
