Effects of whey protein supplementation on adiposity, body weight, and glycemic parameters: A synthesis of evidence.

AIMS: The aim of this review was to analyze the evidence of whey protein supplementation on body weight, fat mass, lean mass and glycemic parameters in subjects with overweight or type 2 diabetes mellitus (T2DM) undergoing calorie restriction or with ad libitum intake. DATA SYNTHESIS: Overweight and obesity are considered risk factors for the development of chronic noncommunicable diseases such as T2DM. Calorie restriction is a dietary therapy that reduces weight and fat mass, promotes the improvement of glycemic parameters, and decreases muscle mass. The maintenance of muscle mass during weight loss is necessary in view of its implication in preventing chronic diseases and improving functional capacity and quality of life. The effects of increased protein consumption on attenuating muscle loss and reducing body fat during calorie restriction or ad libitum intake in overweight individuals are discussed. Some studies have demonstrated the positive effects of whey protein supplementation on improving satiety and postprandial glycemic control in short term; however, it remains unclear whether long-term whey protein supplementation can positively affect glycemic parameters. CONCLUSIONS: Although whey protein is considered to have a high nutritional quality, its effects in the treatment of overweight, obese individuals and those with T2DM undergoing calorie restriction or ad libitum intake are still inconclusive.

Impact of different sports on body mass of female university students / Impacto de distintos esportes sobre as massas corporais de universitárias / Impacto de diferentes deportes en la masa corporal de estudiantes universitarias

ABSTRACT Introduction A healthy body depends on several factors, and physical exercise is one of the main factors. Research results on the physical health of female university students show that although the general health status of Chinese female students is good, the quality of physical performance at university continues to show a slow downward trend. Objective To explore the effects of different exercises on the fat mass and lean weight indices of female university students. Methods 60 female students who participated in aerobics and ball games training in the Physical Education Department of a university were randomly divided into a control group and a training group, with 30 volunteers in each group. The experimental group performed intensive aerobics training and ball training. In contrast, no intervention was performed in the control group, and indicators were collected and analyzed according to current literature. Results After eight weeks of the intervention protocol, the body weight, body fat weight, lean weight, body surface area, and body fat ratio of the control group had no significant changes from the period before the experiment (P > 0.05). In the training group, fat weight decreased significantly (p<0.01), lean mass weight increased significantly (p<0.01), body fat ratio decreased (p<0.01), and body weight and body surface area had no significant changes (p>0.05). PTH and FSH in the training group were significantly higher than in the control group (P < 0.05). As the aerobic exercise level improved in the experimental group, the weight and abdominal skinfold thickness in the exercise group showed a downward trend. Conclusion There is a general correlation between BMI and body fat content and its body distribution in college women. Compared to men, BMI is better suited to describe the fat metabolism of college women. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.

Effects of aerobic exercise on body morphology in obese university students / Efeitos do exercício aeróbico na morfologia corporal de estudantes universitários obesos / Efectos del ejercicio aeróbico en la morfología corporal de estudiantes universitarios obesos

ABSTRACT Introduction The problem of obesity is relevant to the current social development model. In addition to the eminent physical health risks, obese university students also experience greater resistance to social development. Obese students participating in the national weight loss fitness program can perceive the benefits of aerobic exercise. Objective Explore the effect of aerobic exercise on body morphology in obese university students. Methods 60 obese university students were selected as study subjects and divided equally into a control and experimental group. The control group received no intervention, while the experimental group performed a battery of aerobic exercises of 60 minutes daily, four times a week for six weeks. Data before and after the experiment were compared. BMI, body fat rate, blood lipid monitoring, and blood glucose were also taken as body component monitoring indexes, and circumference measurements and proportions were taken as external body monitoring indexes. Results Aerobic exercise can effectively reduce the body weight, body mass index (BMI), body fat rate, and body circumference of college students, decrease body weight, make the body shape more symmetrical, and also improve lipid and glycemic components, thus reducing the complications caused by obesity. Conclusion University professors should perform aerobic training for university students to improve their physical fitness, regulate their physical function, and improve their physical appearance. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.

Understanding weight regain after a nutritional weight loss intervention: Systematic review and meta-analysis.

BACKGROUND & AIMS: The purpose of this systematic review was to analyze the effects of lifestyle interventions on long-term weight maintenance of weight loss. In addition, we seek to address which period is most susceptible to weight regain; and what is the time required for following-up weight maintenance after the intervention. METHODS: Articles published up to August 2020 were identified using the Medline (PubMed), Embase, Web of Science, CENTRAL and Scopus. RESULTS: After the selection process, 27 clinical trials involving 7236 individuals were included. The results showed that around 36 weeks after the end of the intervention, weight variation reduces, and a sign of continuous weight gain begin to occur with some patients (n = 208,209) presenting even a completely regain of the lost weight before one year (∼40-48 weeks). However, some strategies used during the weight loss intervention and maintenance period may impact the amount and when the weight regain happens, like intervention type;, intervention duration;, presence of dietitian on the care team;, and maintenance period with counseling by a health professional at least once a month. CONCLUSION: This systematic review and meta-analysis showed that lifestyle interventions remained effective in maintaining the mean weight (5% lower than baseline weight) after weight loss interventions were over. However, weight regain started 36 weeks after intervention conclusion. And, it turns out, some strategies used during the weight loss intervention and maintenance period may impact the amount and when the weight regain happens. Obesity complexity and chronicity should be considered, therefore constant and lifelong monitoring and support are important.

Maintenance Following a Randomized Trial of a Clinic and Home-based Behavioral Intervention of Obesity in Preschoolers.

OBJECTIVE: To assess maintenance of improved weight outcomes in preschoolers with obesity 6 and 12 months following a randomized clinical trial comparing a home- and clinic-based behavioral intervention (Learning about Activity and Understanding Nutrition for Child Health [LAUNCH]) to motivational interviewing and standard care. STUDY DESIGN: Randomized controlled trial with children between the ages of 2 and 5 years above the 95th percentile for body mass index for age and sex recruited from 27 pediatrician offices across 10 recruitment cycles between March 12, 2012, and June 8, 2015, were followed 6 and 12 months post-treatment. Child and caregiver weight, height, and caloric intake, child physical activity, and home environment were assessed. The primary outcome was maintenance of greater reduction of percent over the 50th percentile body mass index (BMI%50th) by LAUNCH compared with motivational interviewing and standard care at the 6- and 12-month follow-up. RESULTS: Significantly lower child BMI%50th was maintained for LAUNCH compared with motivational interviewing at 12-month follow-up and to standard care at the 6-month follow-up; however, the effect sizes were maintained for comparison with standard care at 12-month follow-up. LAUNCH had significantly lower daily caloric intake compared with motivational interviewing and standard care at both follow-ups and maintained significantly fewer high-calorie foods in the home compared with standard care at 6 and 12 months and compared with motivational interviewing at 12 months. However, caloric intake increased by 12% from post-treatment. LAUNCH caregivers did not maintain improved BMI at follow-up. CONCLUSIONS: LAUNCH showed success in reducing weight in preschoolers. However, maintaining treatment gains post-treatment is more difficult. Treatment may need to last longer than 6 months to achieve optimal results.

Long-term weight loss outcomes after banded Roux-en-Y gastric bypass: a prospective 10-year follow-up study.

OBJECTIVE: To evaluate the weight loss outcomes of banded Roux-en-Y gastric bypass (RYGB) during a 10-year follow-up. SETTING: Private health-providing service, Brazil. METHODS: A prospective study was conducted on 928 patients with obesity who underwent banded RYGB. Patients were divided into 2 groups according to their initial body mass index (BMI), morbid obesity (BMI 35-49.9 kg/m2) and super obesity (BMI ≥50 kg/m2). The percentages of excess weight loss (%EWL) and total weight loss (%TWL) at 18, 24, 36, 48, 60, 72, 84, 96, 108, and 120 months after surgery were assessed and compared, and the rates of surgical failure were also assessed. RESULTS: There were individuals who were lost to follow-up at each year, including 423 (45.6%) at 18 months, 431 (46.4%) at 24 months, 482 (51.9%) at 36 months, 568 (61.2%) at 48 months, 658 (70.9%) at 60 months, 725 (78.1%) at 72 months, 781 (84.2%) at 84 months, 819 (88.3%) at 96 months, 838 (90.3%) at 108 months, and 819 (88.3%) at 120 months. The maximal %EWL was achieved at 18 months (P<.001). After 10 years, there was no significant change in mean BMI (28.7 ± 4.1 versus 28.5 ± 3.6 kg/m2; P = .07) or %EWL (80.4 ± 19.1 versus 79.7 ± 23.4; P = .065), but the mean %TWL was significantly lower at 10 years (30.8 ± 8.5 versus 32.5 ± 8.1; P = .035) in the morbid obesity group, compared with the values observed over 5 years. In the super obesity group, the %EWL significantly decreased from 77.7 ± 16.5 kg/m2 at 24 months to 71.3 ± 18.1 kg/m2 at 72 months (P = .008); at 5 years, mean BMI (33.1 ± 5.8 kg/m2) did not differ from the one observed at 10 years (36.4 ± 5 kg/m2; P = .21), as well as the mean %TWL (40.1 ± 8.5 versus 34.8 ± 8.9; P = .334). CONCLUSION: Banded RYGB leads to significant and sustained weight loss in a 10-year follow-up. Despite a slight late weight regain evaluated by %TWL, RYGB leads to an optimal weight loss in the majority of the individuals.

Weight Loss Success Among Overweight and Obese Women of Mexican-Origin Living in Mexico and the United States: A Comparison of Two National Surveys.

We assessed variations in and correlates of weight-loss success (WLS) among overweight/obese women in Mexico (WIMX) and Mexican-American women (MA). We used cross-national data from 2006 ENSANUT (Mexico) and NHANES (2001-2008) to compare 5061 WIMX with 550 MA's without known metabolic conditions. WLS was defined as losing ≥5 % of body weight over 1 year. MA's were more likely to attain WLS (OR 1.31; 95 % CI 1.01-1.70). WLS among WIMX was higher in those with at least high school, a provider screen of overweight and a lower BMI. Among MA's, an incomplete high school versus primary education reduced the odds of WLS. Among women who lost ≥10 lbs, weight-loss strategies such as eating less were higher among MA's. MA women were more likely than WIMX to attain WLS. Understanding these disparities can help design customized public health interventions that curb the obesity epidemic in these women in both countries.

Efficacy of Healing meditation in reducing anxiety of individuals at the phase of weight loss maintenance: A randomized blinded clinical trial.

OBJECTIVE: To verify the efficacy of Healing Meditation in reducing anxiety levels in individuals on a weight loss maintenance program. DESIGN: A randomized, controlled, evaluator-blinded clinical trial, conducted between January and October 2014, with a follow-up of 12 weeks. SETTING: A weight loss secondary care facility in Salvador, Brazil., of 41 patients at the weight maintenance phase (Mean initial BMI 33.6±4.7kg/m2, who had attained a mean BMI of 24.5±1.6kg/m2 in a median period of 7 months). INTERVENTION: An 8-week Healing Meditation program (n=20), consisting of a 1h weekly meeting, or for a control group on the waiting list (n=21), in addition to the standard clinical program. MAIN OUTCOME MEASURES: Total anxiety was measured by the Hamilton Anxiety Scale (HAM-A), before and after the intervention. Secondary analyses included comparison of the effect of meditation on the somatic and psychic components of the scale. RESULTS: Through an intention to treat analysis, we detected a difference in the mean variation between the intervention and control groups in the total anxiety scores of 7.7 (95% CI 6.3-9.2; Cohen's d=3.41). Means and standard deviations for pre and post intervention anxiety scores were 15.5 (3.4) and 7.8 (2.0) for the intervention group and 14.8 (3.4) and 14.9 (3.4) for the control. CONCLUSION: Healing meditation significantly reduced the anxiety of obese individuals, in the phase of weight maintenance, suggesting this to be an effective auxiliary resource for weight loss maintenance.
