Objective: To assess different factors influencing adiponectinemia in obese and normal-weight women; to identify factors associated with the variation (Δ) in adiponectinemia in obese women following a 6-month weight loss program, according to surgical/non-surgical interventions. Methods: We studied 100 normal-weight women and 112 obese premenopausal women; none of them was on any medical treatment. Women were characterized for anthropometrics, daily macronutrient intake, smoking status, contraceptives use, adiponectin as well as IL-6 and TNF-α serum concentrations. Results: Adiponectinemia was lower in obese women (p < 0.001), revealing an inverse association with waist-to-hip ratio (p < 0.001; r = –0.335). Normal-weight women presented lower adiponectinemia among smokers (p = 0.041); body fat, waist-to-hip ratio, TNF-α levels, carbohydrate intake, and smoking all influence adiponectinemia (r 2 = 0.436). After weight loss interventions, a significant modification in macronutrient intake occurs followed by anthropometrics decrease (chiefly after bariatric procedures) and adiponectinemia increase (similar after surgical and non-surgical interventions). After bariatric intervention, Δ adiponectinemia was inversely correlated to Δ waist circumference and Δ carbohydrate intake (r 2 = 0.706). Conclusion: Anthropometrics...

Doutoramento em Motricidade Humana, na especialidade de Saúde e Condição Física; This thesis derives from three scientific problems which resulted in the same number of scientific articles. The background and questions of this investigation are centre in the methodological area and body composition rules. The first problem analysed the accuracy of some laboratory and field methods available (DXA, BIA and Anthropometry) in assessing body composition changes in overweight and obese women after a 16 months weight loss program management using a four-component molecular model as reference. The second studied the reasons why the changes in weight and body composition may result in functional changes in the thoracic gas volume (VTG) and, consequently, in the inadequate assessment of fat mass through a two-compartment model as Bod Pod. The last problem tested the accuracy of Bod Pod in tracking body composition changes using DXA as reference. It was verified that the single frequency BIA-Tanita device, a field method, showed a good level of performance in tracking body composition changes, similarly to the laboratory methods used, DXA and Bod Pot, despite being a two-compartment model. Draw attention to those different methods should not be applied in different moments interchangeably to detect body composition changes after a weight loss program.; Esta tese é constituída por 3 problemas científicos que deram origem ao mesmo número de artigos científicos. As questões e fundamentos desta tese centraram-se na área metodológica e nas regras da composição corporal. O primeiro problema analisou a validade de alguns dos métodos laboratoriais e de terreno disponíveis (DXA...

OBJECTIVES: The incidence of obesity and particularly super obesity, has increased tremendously. At our institution, super obesity represents 30.1% of all severely obese individuals in the bariatric surgery program. In super obesity, surgical morbidity is higher and the results are worse compared with morbid obesity, independent of the surgical technique. The primary strategy for minimizing complications in these patients is to decrease the body mass index before surgery. Preoperative weight reduction can be achieved by a hypocaloric diet, drug therapy, an intragastric balloon, or hospitalization. The objective of this study was to analyze the results of a period of hospitalization for preoperative weight loss in a group of super-obese patients. METHODS: Twenty super-obese patients were submitted to a weight loss program between 2006 and 2010. The mean patient age was 46 years (range 21-59). The mean BMI was 66 kg/m2 (range 51-98) and 12 were women. The average hospital stay was 19.9 weeks and the average weight loss was 19% of the initial weight (7-37%). The average caloric intake was 5 kcal/kg/day. After the weight loss program...

Dietary and behavioral needs of special populations are rarely considered in traditional weight loss programs. This study assessed the impact of culturally-sensitive modifications to the Duke University Rice Diet weight loss program for African-American dieters. The study was a randomized modified cross-over study in which volunteers received either early or delayed weight loss intervention. Final outcomes were measured at 8 weeks. At the onset of the study, there were 56 African American participants, however, only 44 (79%) completed the study. The eight-week intervention was a modified 1000-calorie/day version of the Rice Diet. Modifications to the program included decreased cost, culturally-sensitive recipes, addressing attitudes about exercise, and including family members in weight loss efforts. Average weight loss for subjects completing the program was 14.8 pounds (SD = 6.8 pounds). BMI decreased from 37.8 kg/m2 to 35.3 kg/m2 (p < 0.01). Total cholesterol levels decreased from 199.2 mg/dL to 185.4 mg/dL (p < 0.01); systolic and diastolic blood pressure decreased by 4.3 mmHg (p < 0.01) and 2.4 mmHg (p < 0.05), respectively. The control group showed no significant change in any outcome measures. We found that diet programs can be successfully tailored to incorporate the needs of African-Americans. Most importantly...

Increased inflammation and weight loss are associated with a reduction in bone mineral density (BMD). Aerobic exercise may minimize the loss of bone and weight loss may contribute to a decrease in cytokines. We tested the hypothesis that aerobic exercise in combination with a weight loss program would decrease circulating concentrations of inflammatory markers, thus mediating changes in BMD. This was a nonrandomized controlled trial. Eighty-six overweight and obese postmenopausal women (50–70 years of age; BMI, 25–40 kg/m2) participated in a weight loss (WL; n = 40) or weight loss plus walking (WL + AEX; n = 46) program. Outcome measures included BMD and bone mineral content of the femoral neck and lumbar spine measured by dual energy X-ray absorptiometry, interleukin-6, tumor necrosis factor-α, soluble receptors of IL-6, and TNF-α (sTNFR1 and sTNFR2; receptors in a subset of the population), VO2 max, fat mass, and lean mass. Weight decreased in the WL (p < 0.001) and WL + AEX (p < 0.001) groups. VO2 max increased (p < 0.001) after WL + AEX. There was a 2% increase in femoral neck BMD in the WL + AEX group (p = 0.001), which was significantly different from the WL group. The change in sTNFR1 was significantly associated with the change in femoral neck BMD (p < 0.05). The change in VO2 max was an independent predictor of the change in femoral neck BMD. Our findings suggest that the addition of aerobic exercise is recommended to decrease inflammation and increase BMD during weight loss in overweight postmenopausal women.

Behavioral studies have suggested that food cues have stronger motivating effects in obese than in normal-weight individuals, which may be a risk factor underlying obesity. Previous cross-sectional neuroimaging studies have suggested that this difference is mediated by increased reactivity to food cues in parts of the reward system in obese individuals. To date, however, only a few prospective neuroimaging studies have been conducted to examine whether individual differences in brain activation elicited by food cues can predict differences in weight change. We used functional magnetic resonance imaging (fMRI) to investigate activation in reward-system as well as other brain regions in response to viewing high-calorie food vs. control pictures in 25 obese individuals before and after a 12-week psychosocial weight-loss treatment and at 9-mo follow-up. In those obese individuals who were least successful in losing weight during the treatment, we found greater pre-treatment activation to high-calorie food vs. control pictures in brain regions implicated in reward-system processes, such as the nucleus accumbens, anterior cingulate, and insula. We found similar correlations with weight loss in brain regions implicated by other studies in vision and attention...

This analysis investigated if changes in autonomous or controlled motivation for participation in a weight loss program differed between individuals offered a financial incentive for weight loss compared to individuals not offered an incentive. Additionally, the same relationships were tested among those who lost weight and either received or did not receive an incentive. This analysis used data from a year-long randomized worksite weight loss program that randomly assigned employees in each worksite to either a low-intensity weight loss program or the same program plus small financial incentives for weight loss ($5.00 per percentage of initial weight lost). There were no differences in changes between groups on motivation during the study, however, increases in autonomous motivation were consistently associated with greater weight losses. This suggests that the small incentives used in this program did not lead to increases in controlled motivation nor did they undermine autonomous motivation. Future studies are needed to evaluate the magnitude and timing of incentives to more fully understand the relationship between incentives and motivation.

The current study aimed to compare the estimates of body fat percentage (%BF) by performing bioelectrical impedance analysis (BIA) and dual energy X-ray absorptiometry (DXA) in a sample of obese or overweight Chinese adults who participated in a weight-loss randomized control trial stratified by gender to determine whether or not BIA is a valid measurement tool. Among 189 adults [73 males, 116 females; age  = 41 to 74 years; mean body mass index (BMI)  = 27.3 kg/m2], assessments of %BF at the baseline and six months from the baseline were conducted by performing BIA and DXA. Bland-Altman analyses and multiple regression analyses were used to assess the relationships between %BFBIA and %BFDXA. Compared with DXA, BIA underestimated %BF [in males: 4.6, –2.4 to 11.7 (mean biases, 95% limit of agreement) at the baseline, 1.4, –7.4 to 10.2 at the endpoint, and 3.2, –4.8 to 11.3 in changes; in females: 5.1, –2.4 to 12.7; 2.2, –6.1 to 10.4; and 3.0, –4.8 to 10.7, respectively]. For males and females, %BFDXA proved to be a significant predictor of the difference between DXA and BIA at the baseline, the endpoint, and in changes when BMI and age were considered (in males: p<0.01 and R2  = 23.1%, 24.1%, 20.7%, respectively; for females: p<0.001 and R2  = 40.4%...

A reduction of visceral fat is important for improvement of metabolic risk. This study was designed to compare the effects of a web-based program alone or together with measurement and self-awareness of accumulated visceral fat in Japanese workers. A new noninvasive device to measure visceral fat accumulation was introduced, and efficacy on weight-loss and improvement of healthy behaviors were examined. This study was conducted according to Helsinki declaration and approved by the ethical committee of Japan Hospital Organization, National Kyoto Hospital. Two-hundred and sixteen overweight and obese males with BMI of more than 23 participated from 8 healthcare offices of 3 Japanese private companies. Subjects were randomly allocated into control group, Web-based weight-loss program (Web), or Web + Visceral fat measurement group (Web + VFA). Eighty-one percent of participants completed the study. Reductions of body weight, waist circumference, and BMI were the largest in Web + VFA group, and the differences between groups were significant by ANOVA. Improvements of healthy behaviors were the largest in Web + VFA group, and the differences of healthy eating improvement scores between Web + VFA and control groups were significant. Our findings suggest that measurement and awareness of visceral fat are effective in weight reduction in overweight and obese males in the workplace.

Obesity is related to high health care costs and lost productivity in the workplace. Employers are increasingly sponsoring weight loss and wellness programs to ameliorate these costs. We evaluated weight loss outcomes, treatment utilization, and health behavior change in a low intensity phone- and web-based, employer-sponsored weight loss program. The intervention included three proactive counseling phone calls with a registered dietician and a behavioral health coach as well as a comprehensive website. At six months, one third of those who responded to the follow-up survey had lost a clinically significant amount of weight (≥5% of body weight). Clinically significant weight loss was predicted by the use of both the counseling calls and the website. When examining specific features of the web site, the weight tracking tool was the most predictive of weight loss. Health behavior changes such as eating more fruits and vegetables, increasing physical activity, and reducing stress were all predictive of clinically significant weight loss. Although limited by the low follow-up rate, this evaluation suggests that even low intensity weight loss programs can lead to clinical weight loss for a significant number of participants.

The ability of obese people to reduce weight in the same treatment varied. Genetic make up as well as the behavioral changes are important for the successfulness of the program. One of the most proposed genetic variations that have been reported in many intervention studies was genes that control lipolysis process. This review summarizes studies that were done showing the influence of genetic polymorphisms in lipolysis pathway and weight loss in a weight loss treatment program. Some studies had shown that certain enzymes involved in this process were related to successfulness of weight loss program. Single Nucleotide Polymorphism (SNP) in PLIN (11482G>A) and ADRB3 (Trp64Arg) are the most studied polymorphisms that have effect on weight loss intervention. However, those studies were not conclusive because of limited number of subjects used and controversies in the results. Thus, replication and confirmation on the role of those genes in weight loss are important due to their potential to be used as predictors of the results of the program.

Human-robot interaction is now well enough understood to allow us to build useful systems that can function outside of the laboratory. This thesis defines sociable robot system in the context of long-term interaction, proposes guidelines for creating and evaluating such systems, and describes the implementation of a robot that has been designed to help individuals effect behavior change while dieting. The implemented system is a robotic weight loss coach, which is compared to a standalone computer and to a traditional paper log in a controlled study. A current challenge in weight loss is in getting individuals to keep off weight that is lost. The results of our study show that participants track their calorie consumption and exercise for nearly twice as long when using the robot than with the other methods and develop a closer relationship with the robot. Both of these are indicators of longer-term success at weight loss and maintenance.; by Cory David Kidd.; Thesis (Ph.

The objective of this study was to examine the effectiveness of a 12 week weight loss intervention in a commercial fitness centre on body mass index (BMI), moderate to vigorous physical activity (MVPA) and behavioural regulations consistent with Organismic Integration Theory (OIT, Deci & Ryan, 2002). The intervention group received weekly coaching sessions and bi-weekly seminars designed to increase MVPA and improve dietary intake. The results of the mixed model analyses of variance showed a significant within-subjects main effect for BMI (F = 3.57, p = .04). Changes in MVPA were not observed over time or between conditions. Changes in behavioural regulations congruent with OIT (Deci & Ryan, 2002) favoured the intervention condition. Study results indicate that 12 week weight loss challenges in commercial fitness centres may be effective to support the internalization process of exercise behavioural regulations but ineffective at producing sustainable weight loss or behavioural changes.

Objective: The well-documented finding that obese adults have a high likelihood of weight regain following participation in behavioural weight loss programs highlights the importance of developing more effective approaches for weight loss maintenance. One promising approach is to improve the quality of social support for effective weight control available to an obese individual by including support people in behavioural weight loss programs. This paper describes the rationale and design of a randomised controlled trial that evaluates the effectiveness of training support people to assist obese adults in their weight management. Design: The study entails a twoarm randomised controlled trial in which obese participants take part in a one-year (26-session) cognitive-behaviour therapy group weight management program including motivational interviewing strategies (CBT-MI). In one arm, participants receive CBT-MI alone, while in the second arm (CBT-MI-SP) participants also have a support person who attends 10 group sessions designed to teach effective skills for supporting an individual in healthy weight control. Assessments of anthropometric, medical, behavioural, psychological, and social functioning take place at pretreatment...

Background: Evidence that high-protein diets are an effective strategy for the maintenance of long-term weight loss is limited. Objective: The objective was to determine the efficacy of a higher protein intake on the maintenance of weight loss after 64 wk of follow-up. Design: Seventy-nine healthy women with a mean (±SD) age of 49 ± 9 y and a body mass index (in kg/m2) of 32.8 ± 3.5 completed an intensive 12-wk weight-loss program and 52 wk of follow-up to compare the effects on weight-loss maintenance of a high-protein (HP) diet (34% of energy) or a high-carbohydrate (HC) diet (64% of energy). Results: Mean (±SD) weight loss was not significantly different between groups: (HP: 4.6 ± 5.5 kg; HC: 4.4 ± 6.1 kg). Protein intake (g) from dietary records at 64 wk was directly related to weight loss (P < 0.0001), accounting for 15% of the variance. Protein intake as a percentage of energy was also related to weight change (P = 0.003), accounting for 10% of the variance. In the upper tertile (88 g protein/d), weight loss was 6.5 ± 7.5 and 3.4 ± 4.4 kg (P = 0.03) in the 2 lower tertiles, respectively. This difference did not translate to a difference in central fat loss between groups. Lipids, glucose, insulin, C-reactive protein...

OBJECTIVE: The objective of the present study was to elucidate the separate effects of energy restriction and weight loss on blood pressure (BP) and to assess the relationship between sodium intake, weight loss, and BP. METHODS: Two hundred and eight overweight and obese subjects (age: 52.4 +/- 0.8 yrs; BMI 33.6 +/- 0.3 kg/m(2)) completed a weight loss diet program consisting of 8-12 weeks of moderate energy restriction (ER; approximately 30% energy deficit, unrestricted salt intake) and four weeks of energy balance (EB). Body weight and BP were measured at baseline, the midpoint, and the end of ER and after EB. 24-hr Na+ excretion was measured at baseline and at the end of EB. RESULTS: Overall, body weight reduced progressively by 7.0 +/- 0.2 kg (7.5%; p < 0.001) with the hypocaloric diet. BP fell substantially during the first phase of ER (-5.7 +/- 0.7/-2.6 +/- 0.4 mmHg, p = 0.001), corresponding to a 4.5 +/- 0.2 kg weight reduction, with no further BP changes during the second phase of ER, despite further weight loss (2.4 +/- 0.1 kg). During EB, BP remained stable. The hypotensive effects of caloric restriction and weight loss were similar across clinical subgroups defined by age, sex, diabetes, insulin sensitivity, and hypertensive status. BP responses to weight loss were independent of 24-hr urinary Na+ excretion. 24-hr urinary Na+ excretion was similar at baseline and at the end of EB (146.5 +/- 5.3 vs. 146.9 +/- 5.3 mmol/24-hr). CONCLUSION: The hypotensive effects of caloric restriction do not rebound upon return to eucaloric intake at a reduced body weight...

Background: The purpose of this study was to examine the relationships between physical activity and healthy eating behaviour with the participant's motives and goals for each health behaviour. Methods: Participants (N 121; 93.2% female) enrolled in commercial weightloss programs at the time of data collection, completed self-reported instruments using a web-based interface that were in accordance with Deci and Ryan's (2002) Self-Determination Theory (SDT). Results: Multiple linear regression models revealed that motivation and goals collectively accounted for between 0.21 to 0.29 percent and 0.03 to 0.16 percent of the variance in physical and healthy eating behaviours in this sample. In general, goals regarding either behaviour did not appear to have strong predictive relationships with each health behaviour beyond the contributions of motives. Discussion: Overall, findings from this study suggest that motives seem to mattermore than goals for both physical activity and healthy eating behaviour in clientele of commercial weight-loss programs. Therefore commercial weight-loss program implementers may want to consider placing more attention on motives I than goals for their clientele when designing weight-loss and weight-maintenance initiatives.

Objective: The goals of this research was (1) to analyze the role of emotional eating behavior on weight-loss progression during a 30-week weight-loss program in 1,272 individuals from a large Mediterranean population and (2) to test for interaction between CLOCK 3111 T/C SNP and emotional eating behavior on the effectiveness of the weight-loss program. Design and Methods: A total of 1,272 overweight and obese participants (BMI: 31±5 kg/m2), aged 20 to 65 years, attending outpatient weight-loss clinics were recruited for this analysis. Emotional eating behavior was assessed by the Emotional Eating Questionnaire (EEQ), a questionnaire validated for overweight and obese Spanish subjects. Anthropometric measures, dietary intake and weight-loss progression were assessed and analyzed throughout the 30-week program. Multivariate analysis and linear regression models were performed to test for gene-environment interaction. Results: Weight-loss progression during the 30-week program differed significantly according to the degree of emotional eating behavior. Participants classified as ‘very emotional eaters’ experienced more irregular (P = 0.007) weight-loss, with a lower rate of weight decline (−0.002 vs. −0.003, P<0.05) in comparison with less emotional eaters. The percentage of weight-loss was also significantly higher in ‘non-emotional eaters’ (P = 0.009). Additionally...

Background: Obesity is the number one health risk facing Americans. The obesity epidemic in America is attributed to physical inactivity, unhealthy food choices, and excessive food intake. Structured weight loss programs have been successful in initiating behavior change and weight loss; however, weight is almost always regained over time. The rate of weight gain is highest immediately after cessation of a structured weight loss program. Thus, effective interventions are needed that can successfully be used following a structured weight loss program to sustain weight loss and prevent weight relapse. Due to low cost, ubiquity, and ease of use, healthcare communicated through mobile technology, or "mHealth", may be able to serve as an effective medium to reach a large number of people to facilitate weight loss behaviors. Short message service (SMS), also known as text messaging, is easy to use, ubiquitous, affordable, and can target people directly where they are regardless of geographic location, socioeconomic status, or demographic factors. A review of the literature demonstrated limited information regarding message content, timing and frequency of message delivery and only 3 of 14 SMS-related interventions reviewed demonstrated a statistically significant effect on weight loss...

The aim of this study was to investigate whether protein supplementation helps prevent the loss of fat-free mass during weight loss. The sample was composed of seventy-eight obese adult Japanese women, assigned into four different programs: diet-alone (D, n=24), diet-alone with protein supplementation (DP, n=16), diet-plusexercise (DE, n=17), and diet-plus-exercise with protein supplementation (DEP, n=21). All participants restricted their energy intakes to 1200 kcal/day, and participants in DE and DEP had the exercise session including aerobic exercise of approximately 90 min/day, 3 day/week. Participants enrolled in protein supplementation groups received an additional 14 g/day of protein. Measures on body composition were conducted before and after the program by DXA. All programs yielded significant weight (6.9 to 9.5 kg) and fat (4.1 to 7.6%) reduction. Total fat-free mass significantly decreased in D, DP and DE groups, whereas for DEP group the decrease was not significant. Regional fat-free mass lowered for D and DP groups in leg, arms and trunk. For those in DE group, fat-free mass in trunk was not significantly decreased, and for those in DEP group, fat-free mass in leg and trunk did not differ significantly after the program. However...
