Objective: This study aimed to compare two energy-restricted, nutrient-dense diets at the upper or lower ends of the dietary fat recommendation range (lower fat [20% energy from fat] versus moderate fat [35%]) on weight loss using behavioral theory-based nutrition education.
Methods: A total of 101 premenopausal women with overweight or obesity were randomized to an energy-restricted lower-fat or moderate-fat diet for 1 year. Interventions included 28 behavioral theory-based nutrition education sessions plus weekly exercise sessions.
Background: Proper nutrition during early life is critical for growth and development.
Objectives: The aim was to describe systematic reviews conducted by the Nutrition Evidence Systematic Review team for the USDA and the Department of Health and Human Services Pregnancy and Birth to 24 Months Project to answer the following: What is the relation between 1) timing of introduction of complementary foods and beverages (CFBs) or 2) types and/or amounts of CFBs consumed and micronutrient status (iron, zinc, vitamin D, vitamin B-12, folate, and fatty acid status)?
Methods: A literature search identified articles from developed countries published from January 1980 to July 2016 that met the inclusion criteria. Data were extracted and risk of bias assessed.
The USDA's Nutrition Evidence Systematic Review (NESR) team specializes in conducting systematic reviews (SRs) to inform federal nutrition policy and programs. The NESR's dedicated staff collaborate with leading scientists to answer important food- and nutrition-related public health questions by objectively reviewing, evaluating, and synthesizing research using state-of-the-art methodology. NESR uses a rigorous, protocol-driven methodology that is designed to minimize bias; to ensure availability of SRs that are relevant, timely, and high quality; and to ensure transparency and reproducibility of findings.

Design: Randomized, parallel-arm with weight loss phase (baseline to month 4) and weight-maintenance phase (months 4-12).
Setting: Face-to-face in University classrooms, supervised and self-directed fitness sessions at University fitness center, and home.
Strategic translational research is designed to address research gaps that answer specific guidance questions. It provides translational value with respect to nutrition guidance and regulatory and public policy. The relevance and the quality of evidence both matter in translational research.

Objective, Design, And Setting: In a randomized, double-blind, placebo-controlled, crossover study, we examined the effects of the MC4R agonist RM-493 on resting energy expenditure (REE) in obese subjects in an inpatient setting.
Current literature provides limited information about healthy volunteers serving as controls for biomedical research. This study describes trends in body mass index (BMI), a ratio of weight to height (kilograms per square meter), of the population of healthy volunteers at the National Institutes of Health Clinical Center (NIH CC) and compares these trends to a nationally representative sample, as reported by the National Health and Nutrition Examination Survey. We hypothesized that BMI trends at the NIH CC would follow those of the US population.

This study examined weight cycling prevalence among African American women prior to enrolling in a weight management program. Associations of weight cycling with physical and psychological health were conducted.

This study compared changes in body weight and composition and blood lipids after short-term weight loss (4 mo) followed by weight maintenance (8 mo) using moderate PRO or conventional high-carbohydrate (CHO) diets. Participants (age = 45.
