Efficacy of Lifestyle Modification for Long-Term Weight Control
Department of Psychology, Drexel University, Filadelfia, Pennsylvania, United StatesObesity research (Impact Factor: 4.95). 01/2005; 12 Suppl(S12):151S-62S. DOI: 10.1038/oby.2004.282
A comprehensive program of lifestyle modification induces loss of approximately 10% of initial weight in 16 to 26 weeks, as revealed by a review of recent randomized controlled trials, including the Diabetes Prevention Program. Long-term weight control is facilitated by continued patient-therapist contact, whether provided in person or by telephone, mail, or e-mail. High levels of physical activity and the consumption of low-calorie, portion-controlled meals, including liquid meal replacements, can also help maintain weight loss. Additional studies are needed of the effects of macronutrient content (e.g., low-fat vs. low-carbohydrate diets) on long-term changes in weight and health. Research also is needed on effective methods of providing comprehensive weight loss control to the millions of Americans who need it.

- "MBIs, as with any behavioural intervention, require regular practice to be effective. It is worthwhile to note that the issues of long-term acceptability, adherence and sustainability are not exclusive to MBIs, as these issues are also present in other behavioural interventions such as physical activity and dietary programmes, as well as medical treatments (McAuley et al., 2003;Osterberg and Blaschke, 2005;Wadden et al., 2004). Thus, the implications for future research are that it is not only important to record Mindfulness measures pre-intervention, immediately post-intervention, and at longerterm follow-up, it is also integral to the treatment's evaluation to assess and report if participants continue to incorporate regular Mindfulness methods into their lives following completion of the intervention. "
ABSTRACT: This systematic review aimed to examine the effectiveness of Mindfulness-based interventions in reducing diabetes-related physiological and psychological symptoms in adults with types 1 and 2 diabetes. Five databases were systematically searched. A total of 11 studies satisfied the inclusion criteria. Mindfulness-based intervention effectiveness for physiological outcomes (glycaemic control and blood pressure) was mixed. Mindfulness-based interventions appear to have psychological benefits reducing depression, anxiety and distress symptoms across several studies. Studies' short-term follow-up periods may not allow sufficient time to observe physiological changes or illustrate Mindfulness-based interventions' potential long-term efficacy. More long-term studies that include a consistent, standardised set of outcome measures are required.

- "Tailored information may consist of, for example, personal recommendations for achieving a set goal (e.g. Wadden et al., 2004). Monitored information is gathered by input data on the user and may take the form of progress charts intended to encourage the user to keep track of the process and to enhance exercising in the newly adopted behaviour (e.g. "
ABSTRACT: Purpose ‐ The purpose of this paper is to increase understanding of the role of information and knowledge in the context of health behaviour change. Design/methodology/approach ‐ As internet use in Finland is among the highest in Europe, two Finnish web-based weight management services were analysed regarding their weight maintenance information by using a theoretical approach constructed for the purpose. The approach combines the elements of web-based weight maintenance information and the typologies of knowing and actional information. The approach was tested by examining the services deductively with theory-based content analysis. Findings ‐ The approach indicated differences between the profiles of the two analysed information environments, which focus on factual and tailored information and their relation to pragmatic, provisional and contested knowing and the initiation, maintenance and recovery of actional information. Both services support weight maintenance; the other slightly more due to its rich social features. Research limitations/implications ‐ The examination was focused on the free content of two Finnish weight management services. Further research should include the role of socially interactive information and further testing of the approach with more services. Practical implications ‐ The proposed approach sheds light on the relationship between the types of weight maintenance information and the dimensions of the typologies of knowing and actional information. The approach has the potential to be applied when designing the information environment of new web-based weight management services. Social implications ‐ The approach has potential to be applied when designing the information content of new web-based weight management services to support health behaviour change. The approach could be elaborated further by focusing on enabling social support required in long-term weight maintenance. Originality/value ‐ The study adopted a novel approach to studying typologies of knowing and actional information, thus providing new viewpoints in both information behaviour and organisational knowledge. The study enables further research on weight maintenance information use by proposing a theoretical background.

- "The routine calorie restriction regimens always induce a quick weight loss at beginning and reach the maximum effect after 6 months, from which moreover weight loss or establishing the current weight is difficult and approximately, 30-35% of lost weight is regained during the 1st year after treatment. Calorie restriction diet in present study was successful in weight and fat decrease after 6 weeks of treatment; however, the weight regained after 4 weeks of follow-up period (−2.18 kg compared to week 6 of CR). "
ABSTRACT: Finding new tolerable methods in weight loss has largely been an issue of interest for specialists. Present study compared a novel method of calorie shifting diet (CSD) with classic calorie restriction (CR) on weight loss in overweight and obese subjects. Seventy-four subjects (body mass index ≥25; 37) were randomized to 4 weeks control diet, 6 weeks CSD or CR diets, and 4 weeks follow-up period. CSD consisted of three phases each lasts for 2 weeks, 11 days calorie restriction which included four meals every day, and 4 h fasting between meals follow with 3 days self-selecting diet. CR subjects receive determined low calorie diet. Anthropometric and metabolic measures were assessed at different time points in the study. Four weeks after treatment, significant weight, and fat loss started (6.02 and 5.15 kg) and continued for 1 month of follow-up (5.24 and 4.3 kg), which was correlated to the restricted energy intake (P < 0.05). During three CSD phases, resting metabolic rate tended to remain unchanged. The decrease in plasma glucose, total cholesterol, and triacylglycerol were greater among subjects on the CSD diet (P < 0.05). Feeling of hunger decreased and satisfaction increased among those on the CSD diet after 4 weeks (P < 0.05). The CSD diet was associated with a greater improvement in some anthropometric measures, Adherence was better among CSD subjects. Longer and larger studies are required to determine the long-term safety and efficacy of CSD diet.
