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.

    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[1819] and approximately, 30-35% of lost weight is regained during the 1st year after treatment.[20] 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.

    • "The teleconference environment is comfortable and convenient, provides privacy, is readily accessible without transportation, and can increase participation [40,41]. Also, group intervention can be effective because it provides empathy, social support, and a healthy dose of competition [13]. Thus, the combination of DVDs and PSGTs has great potential for promoting healthy lifestyle and meeting the needs of low-income mothers. "

    ABSTRACT: Over 45% of American women 20-39 years old are at risk for type 2 diabetes, cardiovascular disease, and other health conditions because they are overweight or obese. The prevalence of overweight and obesity is disproportionately high among low-income women. This paper describes the study design and rationale of a community based intervention (Mothers In Motion, MIM) aimed to prevent weight gain among low-income overweight and obese mothers18-39 years old by promoting stress management, healthy eating, and physical activity.Methods/design: Peer recruiters approached participants from 5 Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) in Michigan. The MIM delivers theory-based, culturally-sensitive intervention messages via a combination of DVDs and peer support group teleconferences (PSGTs). The DVD features African American and white overweight and obese WIC mothers who participated in a healthy lifestyle intervention patterned after MIM. The PSGTs are led by paraprofessionals from Michigan State University Extension and WIC providers in Michigan who are trained in motivational interviewing and group facilitation skills. Participants are randomly assigned to an intervention (n = 350) or comparison group (n = 175). The intervention group receives a 16-week intervention on a weekly or bi-weekly basis. Participants are asked to watch 10 MIM DVD chapters at home and join 10 PSGT sessions by phone. The comparison group receives printed educational materials. The primary outcome is body weight. Secondary outcomes include dietary fat, fruit, and vegetable intake; physical activity; stress, and affect. Mediators are self-efficacy, emotional coping response, social support, and autonomous motivation. Telephone interviews and in-person data collection at WIC offices occur at 3 time points: baseline, immediately, and 3 months after the 16-week intervention. If MIM shows effectiveness, it could have a favorable impact on public health and community programs. The DVDs and PSGTs will be disseminated in WIC, Extension, clinical practice that promote healthy lifestyles for similar target audiences to make a broad contribution to the prevention of weight gain in low-income mothers. Also, our methodology can be adapted by researchers and community stakeholders to help other low-income populations prevent weight gain.Trial regestration: Clinical Trials Number: NCT01839708.
