BACKGROUND Obesity is a global public health challenge, and there is a need for more evidence-based self-management programs that support longer term, sustained weight loss. OBJECTIVE This study used data from the CSIRO Total Wellbeing Diet Online to determine the reach and weight loss results over its first five years. METHODS Participants were adults who joined the commercial weight loss program of their own volition between October 2014 and September 2019 (N=61,164). Information collected included year of birth, sex, height and weight, and usage data, for example entries into the food diary, views of the menu and program content. Weight loss and percentage of starting body weight lost were calculated. Members were divided into two groups for analysis: ‘Stayers’ were members who signed up to at least 12 weeks of the program and recorded a weight entry at baseline and at the end of the program; ‘Starters’ started the program but did not record a weight after 12 weeks. Descriptive statistics and multiple linear regression were used to describe weight loss and determine the member and program characteristics associated with weight loss. RESULTS Data were available from 59,686 members for analysis. Members were predominately female (n=48979/59686; 82%) with an average age of 50 years (SD=12.6). The average starting weight was 90.2kg (SD=19.7) and over half of all members were obese (n=34195/59688, 57%). At week-12, 95% of members had an active program membership which decreased to 41% at 24 weeks. At week 12, 52% of remaining members were actively using the platform, and by week 24, 27% were using the platform. The average weight loss for all members was 2.8kg or 3.1% of starting body weight. Stayers lost 4.9kg (5.3% of starting body weight), compared to starters who lost 1.6kg (1.7% of starting body weight). Almost half (49%) the members who stayed on the program lost 5% or more of their starting body weight, and 16% achieved a weight loss of 10% or more. Of members who were Class 1 obese when they joined the program, 41% who stayed on the program were no longer obese at the end, and across all categories of obesity 24% were no longer obese at the end of the program. Based on multiple linear regression, platform usage was the strongest predictor of weight loss (beta=.263; P<.001), with higher usage associated with greater weight loss. CONCLUSIONS This comprehensive evaluation of a commercial, online weight loss program showed that it was effective for weight loss, particularly for members who finished the program and were active in using the platform and tools provided. If the results demonstrated here can be achieved at an even greater scale, the potential social and economic benefits will be extremely significant. CLINICALTRIAL not applicable.

The success of a weight loss program for pets depends on the owners collaboration. Their compliance is fundamental in establishing the correct food management. The objective of this study was to compare the effectiveness of a weight loss program in two groups of dogs, one maintained under experimental conditions and the other with their owners. The same hypocaloric food was used to feed all animals, the amount being restricted to 60% of the estimated maintenance energy requirement for a 15% reduction of the present body weight of the dog. The animals were followed during 90 days. A standard questionnaire was used to study the owners' perception of obesity and its treatment. The protocol and the diet were found to be effective. The control dogs had an average weight loss of 1.39% per week. Dogs with owners lost on average 0.75% of their body weight per week, a statistically lower result (P<0.05), suggesting that the owners did not follow the treatment closely. The owners were clearly satisfied with the results that were obtained, even with this modest weight loss. The questionnaires were shown to be an important tool in determining the causes of canine obesity, as well as in the follow-up of the treatment.

In this study, we assessed the influences of change in moderate-to-vigorous physical activity (MVPA)/sedentary time (ST) of caregivers participating in a commercial weight-loss program on their children’s change in MVPA/ST. Data from 29 caregivers and their children were collected over 8 weeks. We used multivariable linear regression to assess associations of changes in caregiver’s percent of time spent in MVPA/ST and changes in their child’s percent of time spent in MVPA/ST. For caregivers that decreased body mass index (BMI) over 8 weeks, changes in caregivers’ MVPA was strongly associated with the change in children’s MVPA (β = 2.61 [95% CI: 0.45, 4.77]) compared to caregivers who maintained/increased BMI (β = 0.24 [–2.16, 2.64]). Changes in caregivers’ ST was strongly associated with changes in children’s ST (β = 2.42 [1.02, 3.81]) compared to caregivers who maintained/increased BMI (β = 0.35 [–0.45, 1.14]). Findings reinforce encouraging caregivers to enroll in weight-loss programs for the benefit of their children as well as for themselves.

Abstract Purpose To assess the correlation of peripheral nerve and skeletal muscle magnetization transfer ratio (MTR) with demographic variables. Methods In this study 59 healthy adults evenly distributed across 6 decades (mean age 50.5 years ±17.1, 29 women) underwent magnetization transfer imaging and high-resolution T2-weighted imaging of the sciatic nerve at 3 T. Mean sciatic nerve MTR as well as MTR of biceps femoris and vastus lateralis muscles were calculated based on manual segmentation on six representative slices. Correlations of MTR with age, body height, body weight, and body mass index (BMI) were expressed by Pearson coefficients. Best predictors for nerve and muscle MTR were determined using a multiple linear regression model with forward variable selection and fivefold cross-validation. Results Sciatic nerve MTR showed significant negative correlations with age (r = −0.47, p < 0.001), BMI (r = −0.44, p < 0.001), and body weight (r = −0.36, p = 0.006) but not with body height (p = 0.55). The multiple linear regression model determined age and BMI as best predictors for nerve MTR (R2 = 0.40). The MTR values were different between nerve and muscle tissue (p < 0.0001), but similar between muscles. Muscle MTR was associated with BMI (r = −0.46, p < 0.001 and r = −0.40, p = 0.002) and body weight (r = −0.36, p = 0.005 and r = −0.28, p = 0.035). The BMI was selected as best predictor for mean muscle MTR in the multiple linear regression model (R2 = 0.26). Conclusion Peripheral nerve MTR decreases with higher age and BMI. Studies that assess peripheral nerve MTR should consider age and BMI effects. Skeletal muscle MTR is primarily associated with BMI but overall less dependent on demographic variables.

In this study, we describe changes of plasma levels of the hypothalamic neuropeptide orexin A in obese children during the reduction of body weight and its relationship to other biochemical and anthropometrical parameters. We measured orexin A fasting plasma levels by the RIA method in 58 obese children--33 girls and 25 boys; mean age 13.1+/-0.38 years (range 7-18.5) before and after 5 weeks of weight-reduction therapy. Leptin, IGF-1, and IGFBP-3 levels were measured in all the subjects and were compared to orexin A levels and anthropometrical data. Average weight in subjects before weight-reduction was 74.2+/-2.79 kg and after weight-loss 67.4+/-2.60 kg (p<0.0001). Orexin A levels before the therapy were 33.3+/-1.97 pg/ml and after the therapy 51.7+/-3.07 pg/ml (p<0.0001). Levels of orexin A were not significantly different between girls and boys (p=0.7842). We found negative correlation between orexin A and age (r = -0.5395; p<0.0001), body height (r = -0.4751; p=0.0002), body weight (r = -0.4030; p=0.0017) and BMI (r = -0.2607; p=0.0481). No correlation was found between orexin A and IGF-1, IGFBP-3 or leptin. Orexin A plasma levels increased during body weight loss, whereas the reverse was true for leptin levels. These findings support the hypothesis that orexin A may be involved in regulation of nutritional status in children.

Introduction An adequate level of nutrition is important in the period of reconvalescence in patients undergoing major surgery, in particular due to neoplastic disease. Bioelectrical impedance (BIA - Bioelectrical Impedance Analysis) is a widely used technique for assessing body composition. BIA measurement is easy, fast, cheap and repeatable. Material and methods The body composition of 56 patients (25 women and 31 men) was assessed with bioelectrical impedance analysys. All patients was hospitalized and operated in the Department of General and Oncological Surgery, Wrocław Clinical University Hospital in 2017-2018. Results The average weight loss on the 4th postoperative day is 1.32%, and at discharge from hospital 4.23% of body weight in relation to body weight at admission to the ward. The percentage of fat tissue (FM-Fatt Mass) in patients admitted to the ward is above the normal range. The change in body weight composition in hospitalized patients is mainly related to the amount of adipose tissue and the amount of extra- and intracellular water (ECW-Extracellular Water, ICW-Intracellular Water). Conclusions Bioelectrical impedance can be an easy and effective method to assess body composition and its change in patients undergoing major surgery. Patients operated on due to pancreatic cancer lose the highest percentage of body weight until discharge from the ward in relation to body weight at the time of admission to the ward from the analyzed groups. Weight loss mainly occurs as fat loss (FM).

Purpose. Assessing the results of winter keeping of paddlefish young-of-the-year in ponds of the Forest-steppe and Polesye of Ukraine. Methodology. The study was carried out using 0.05-1.0 ha ponds intended for winter keeping of carps. The stocking density of paddlefish young-of-the-year with an average weight of 94.2-147.2 g in wintering ponds was 4.10-16.63 thousand fish/ha. The study of the physicochemical parameters of the aquatic environment was carried out according to the methods generally accepted in hydrochemistry and fish farming. The main piscicultural-biological parameters during the wintering period of fish were assessed using methods commonly used in ichthyology and fish farming according to the level of survival and body weight loss of paddlefish. Findings. The environmental conditions in the ponds during most of the wintering period of fish met the biological requirements of the studied object of cultivation. The water temperature varied within 0.9-6.50C. The dissolved oxygen content in water did not fall below 3.6-3.8 mgO2/dm3 and was mainly at the level of 3.9-7.9 3.9-7.2 mgO2/dm3. Other hydrochemical parameters were within acceptable values ​​for wintering fish in pond conditions. As a result, the survival rate of paddlefish young-of-the-year during the wintering period was 81.5-89.7%. The body weight loss of fish during the winter keeping was on average in the range of 6.41-8.17%. A conclusion was made on the need to conduct additional studies of physiological and biochemical parameters of paddlefish during the wintering period. Originality. New data were obtained on the peculiarities of wintering of paddlefish seeds in ponds of the Forest-steppe and Polesye of Ukraine. Practical value. The study results are part of the database for the development of improved technologies for sturgeon breeding in Ukraine. Key words: paddlefish, fish seeds, pond aquaculture, fish wintering, environmental conditions, piscicultural parameters.
