Public and health professionals' misconceptions about the dynamics of body weight gain/loss.

Human body energy storage operates as a stock-and-flow system with inflow (food intake) and outflow (energy expenditure). In spite of the ubiquity of stock-and-flow structures, evidence suggests that human beings fail to understand stock accumulation and rates of change, a difficulty called the stock-flow failure. This study examines the influence of health care training and cultural background in overcoming stock-flow failure.

Branched-chain amino Acid plus glucose supplement reduces exercise-induced delayed onset muscle soreness in college-age females.

Supplementation with branched-chain amino acids (BCAAs) has been used to stimulate muscle protein synthesis following exercise. The purpose of this study was to determine if supplementation with BCAAs in combination with glucose would reduce exercise-induced delayed onset muscle soreness (DOMS). Using a double-blind crossover design, 20 subjects (11 females, 9 males) were randomly assigned to either BCAA (n = 10) or placebo (n = 10) groups.

Minimal in-person support as an adjunct to internet obesity treatment.

Background: Internet-based weight-loss programs appear promising in the short-term but, to date, have not been able to produce the level of weight loss seen in traditional in-person treatment; thus, novel approaches are necessary. Using a combination of interactive technology and in-person support has been beneficial in other areas of medicine.

Purpose: The aim of this study is to compare 12-month weight-loss outcomes of an Internet-only behavioral weight-loss treatment with the same program supplemented with monthly in-person meetings.

Weight loss on the web: A pilot study comparing a structured behavioral intervention to a commercial program.

Objective: Internet weight loss programs have become widely available as alternatives to standard treatment, but few data are available on their efficacy. This study aimed to investigate the effectiveness of a structured behavioral weight loss website (VTrim) vs. a commercial weight loss website (eDiets.

Effect of internet support on the long-term maintenance of weight loss.

Objective: To investigate the efficacy of an Internet weight maintenance program.

Research Methods And Procedures: Two hundred fifty-five healthy overweight and obese adults (mean +/- SD BMI, 31.8 +/- 4.
