We address the problem of dynamically maintaining minimum weight hyperpaths in a directed hypergraph in a decremental setting. For such a problem, we provide a new efficient algorithm that works for a wide class of hyperpath weight measures. This algorithm explicitly updates minimum weight hyperpaths in O(L ·C+max{n,C} · size(H)) worst case time under a sequence of L hyperarc weight increments ...

Nuts are rich sources of multiple nutrients and phytochemicals associated with health benefits, including reduced cardiovascular disease risk. This has prompted recommendations to increase their consumption. However, they are also high in fat and are energy dense. The associations between these properties, positive energy balance and body weight raise questions about such recommendations. Numer...

OBJECTIVE The purpose of this study was to evaluate available variables of a long-term weight maintenance study to investigate possible factors predisposing to weight regain after a period of weight loss. RESEARCH METHODS AND PROCEDURES The Maastricht Weight Maintenance Study is an ongoing longitudinal study of healthy men and women (29 men and 62 women; 18 to 65 years of age; BMI = 30.2 +/- ...

We performed a systematic review of the behavioral lifestyle intervention trials conducted in the United States published between 1990 and 2011 that included a maintenance phase of at least six months, to identify intervention features that promote weight loss maintenance in African American women. Seventeen studies met the inclusion criteria. Generally, African American women lost less weight ...

BACKGROUND Weight lost by obese patients is almost always regained over time. Extended treatment may improve maintenance, but solid evidence is lacking. PURPOSE We determined effectiveness of maintenance therapy after a weight loss program. METHODS Together 201 patients (mean age 47 years and BMI 42 kg/m(2), 71% women) were randomly assigned to either a 17-week weight loss program followed ...

Background The world-wide prevalence of overweight and obesity among children and adolescents has reached an alarming level and become a major health problem in today’s world. The aim of this study was to identify the stages and processes of change as well as their relationship with weight controlbased on a Trans- theoretical Model (TTM) in overweight and obese Iranian adolescents. Materials an...
