ABSTRACT Frequent self-weighing has been proposed as an adjuvant strategy to promote weight loss. Not all experts agree on its utility, and the literature supporting its effectiveness is somewhat limited by methodologic shortcomings related to the subjective assessment of self-weighing frequency.
A prospective cohort design was utilized to examine 100 participants enrolled in a weight-loss trial that encouraged frequent, objectively measured self-weighing at home. Measurements were made at pretreatment and at follow-up visits at 6 and 12 months.
Participants were employed, obese adults enrolled in the Weigh By Day trial. Study data were collected between October 2005 and May 2007.
The intervention consisted of a 6-month behavioral weight-loss program that employed telephone counseling, a written manual, and a home telemonitoring scale.
The primary outcomes of interest were body weight and clinically meaningful weight loss (i.e., > or =5%). Analyses were performed in March 2008.
Self-weighing was a significant predictor of body weight over time. Participants lost about 1 extra pound for every 11 days they self-weighed during treatment. In addition, participants who self-weighed at least weekly were 11 times more likely to lose at least 5% of their pretreatment weight after 6 months. Improvements attenuated after 12 months.
Self-weighing may be a strategy to enhance behavioral weight-loss programs. Weekly self-weighing seems to be a reasonable, evidence-supported recommendation for successful weight loss, but more research is warranted to determine the independent contribution of self-weighing to successful weight loss, as well as its potential risk of negative psychological impact.

    ABSTRACT: Objective Regular self-weighing, which in this article is defined as weighing oneself regularly over a period of time (e.g., daily, weekly), is recommended as a weight loss strategy. However, the published literature lacks a review of the recent evidence provided by prospective, longitudinal studies. Moreover, no paper has reviewed the psychological effects of self-weighing. Therefore, the objective is to review the literature related to longitudinal associations between self-weighing and weight change as well as the psychological outcomes.Methods Electronic literature searches in PubMed, Ovid PsycINFO, and Ebscohost CINAHL were conducted. Keywords included overweight, obesity, self-weighing, etc. Inclusion criteria included trials that were published in the past 25 years in English; participants were adults seeking weight loss treatment; results were based on longitudinal data.ResultsThe results (N = 17 studies) revealed that regular self-weighing was associated with more weight loss and not with adverse psychological outcomes (e.g., depression, anxiety). Findings demonstrated that the effect sizes of association between self-weighing and weight change varied across studies and also that the reported frequency of self-weighing varied across studies.Conclusions The findings from prospective, longitudinal studies provide evidence that regular self-weighing has been associated with weight loss and not with negative psychological outcomes.

    • "blood pressure devices, pedometers and standardized weighing scales for use at home) in lifestyle and pharmaceutical counseling. The use of each of these devices has demonstrated improvements on the specific risk factors [8-11] and in the case of home blood pressure measurements even led to a decreased use of medication [12]. Self-monitoring of combined parameters is already successfully being used in chronic heart failure patients [13]. "

    ABSTRACT: Treatment goals for cardiovascular risk management are generally not achieved. Specialized practice nurses are increasingly facilitating the work of general practitioners and self-monitoring devices have been developed as counseling aid. The aim of this study was to compare standard treatment supported by self-monitoring with standard treatment without self-monitoring, both conducted by practice nurses, on cardiovascular risk and separate risk factors. Men aged 50–75 years and women aged 55–75 years without a history of cardiovascular disease or diabetes, but with a SCORE 10-year risk of cardiovascular mortality ≥5% and at least one treatable risk factor (smoking, hypertension, lack of physical activity or overweight), were randomized into two groups. The control group received standard treatment according to guidelines, the intervention group additionally received pro-active counseling and self-monitoring (pedometer, weighing scale and/ or blood pressure device). After one year treatment effect on 179 participants was analyzed. SCORE risk assessment decreased 1.6% (95% CI 1.0–2.2) for the control group and 1.8% (1.2–2.4) for the intervention group, difference between groups was .2% (−.6–1.1). Most risk factors tended to improve in both groups. The number of visits was higher and visits took more time in the intervention group (4.9 (SD2.2) vs. 2.6 (SD1.5) visits p < .001 and 27 (P25 –P75:20–33) vs. 23 (P25 –P75:19–30) minutes/visit p = .048). In both groups cardiovascular risk decreased significantly after one year of treatment by practice nurses. No additional effect of basing the pro-active counseling on self-monitoring was found, despite the extra time investment. Trial registration NTR2188

    • "Two features of internet weight loss programmes that have been associated with weight loss are use of self monitoring tools and peer social support. Self-monitoring of weight and target behaviours has long been recognized as an important tool for weight control [19,20], and keeping diary records of diet, exercise or weight is associated with successful weight loss and weight maintenance [14,20-22]. Reports from programme participants also support the value of self-monitoring [23]. "

    ABSTRACT: The Internet provides a widely accessible platform for weight loss interventions. Automated tools can allow self-guided monitoring of food intake and other target behaviours that are established correlates of weight change. Many programmes also offer social support from the virtual community. The aim of this research was to assess associations between engagement with self-monitoring tools and social support, and weight loss in an online weight-control programme. This paper describes a retrospective analysis of weight change among 3621 subscribers to a commercial Internet-based weight loss programme. Participants were all subscribers (2979 women; 642 men) joining the programme between July 2005 and November 2008 with two or more recorded weights spanning at least 28 days of participation in the programme. Engagement was indexed with frequency of using online diet and exercise diaries and with use of the social support forums. Programme engagement was associated with weight loss in both men and women after controlling for initial BMI and duration of participation. The three engagement variables accounted for 13% of variance in percentage weight loss in women (p < .001) and 19% in men (p < .001). In analyses including all the engagement variables, exercise diary use was an independent predictor of weight loss among men, but non-significant in women. In contrast, use of the online forums was associated with weight loss in women but not in men. Among participants who were overweight or obese, those in the highest tertile of engagement with food diaries (vs the lowest) were more likely to achieve clinically significant (> 5%) weight loss (men: OR = 3.45 p < .001; women: OR = 5.05 p < .001). Being in the highest tertile of engagement with exercise diaries was associated with clinically significant weight loss in men (OR = 3.48 p < .001) and, less strongly, in women (OR = 1.46 p < .05). Use of self-monitoring tools and participation in online support are predictive of weight loss in the context of a commercial, online weight control programme.
