Is there a guideline for how long obesity interventions should be to have an effect?5 answersThe optimal duration of obesity interventions to achieve significant effects remains uncertain. Research has shown that family-based behavioral treatments targeting children aged 8 to 12 years with intensive sessions over 6 months have effectively improved weight status. Guidelines recommend lifestyle interventions for sustained weight loss, with a 3% to 5% reduction considered clinically important, but specifics on intervention duration are lacking. A systematic review on childhood obesity interventions found no clear association between the duration of behavioral interventions and weight-related outcomes, indicating a wide variation in intervention lengths and intensities. Critiques of obesity prevention trials suggest that longer-term interventions extending over the first 1000 days, with improved outcome measures and a global focus, could provide more informative results. In the context of postpartum weight management, short and intensive interventions starting in the postpartum period have shown success, while the effectiveness of interventions starting in pregnancy remains inconclusive.
What is relation between self-determination framework in weight control behavior?5 answersSelf-determination theory (SDT) provides a framework for understanding motivation and behavior change in weight control. SDT posits that humans have three basic psychological needs: competence, relatedness, and autonomy. These needs influence individuals' motivation and self-governance in various behavioral contexts, including weight control. SDT suggests that the quality of support individuals receive from important others, such as autonomy support versus controlling behaviors, is a crucial predictor of psychological need satisfaction and engagement in health-conducive behaviors like physical activity and healthy eating. Interventions grounded in SDT have been shown to be effective in weight management, promoting autonomous forms of exercise regulation, intrinsic motivation, and facilitating exercise adherence, leading to clinically significant weight reduction. The specific dimensional parenting model related to SDT, which includes autonomy support, provision of structure, and parental positive involvement, can be applied to conceptually organize parenting practices relevant to children's obesity-related behaviors.
Is weight loss achieved by lifestyle interventions long-lasting?4 answersWeight loss achieved through lifestyle interventions is not always long-lasting. While a multimodal patient-centered approach that includes dietary changes, physical activity, and behavioral therapies is foundational for durable weight loss, studies have shown that only a small percentage of participants in lifestyle interventions are able to maintain significant weight loss in the long term. Repeated weight cycling and the removal of pharmacological interventions after acute weight loss have been associated with weight regain. Surgical procedures, on the other hand, have been reported to produce larger weight loss and have a more favorable impact on long-term weight loss maintenance. Frequent and sustained lifestyle interventions are necessary to achieve clinically significant weight loss. ICT-based interventions have also shown promise in supporting postpartum women to achieve weight loss, but challenges with adherence to the interventions over time have been reported.
What is the relationship between strength training and weight loss?5 answersStrength training has been shown to have a positive relationship with weight loss. Studies have found that strength training can effectively contribute to the weight loss process when combined with aerobic exercise training and diet. Strength training helps to increase or maintain the resting metabolic rate, leading to increased energy expenditure. It also contributes to energy expenditure during the activity itself. Additionally, strength training has been found to have an effect on excessive oxygen consumption after exercise, further contributing to weight loss. Furthermore, strength training has been shown to increase the capability for balance recovery, which can be beneficial for individuals with obesity who are at an increased risk of falls and injury. Overall, strength training plays a significant role in weight loss and can be an effective strategy when combined with other interventions such as aerobic exercise and diet.
What are the long-term effects of weight loss?5 answersWeight loss has long-term effects on biomarkers of angiogenesis, specifically VEGF and PEDF, in postmenopausal overweight/obese women. Participants who maintained weight loss through diet and/or exercise had significant reductions in VEGF levels at 30 months compared to those who gained weight or had no weight change. These reductions in VEGF were observed in participants randomized to diet, exercise, and diet + exercise arms, indicating the effectiveness of these interventions in achieving sustained weight loss. However, there were no statistically significant changes in PEDF levels in any intervention arm. These findings suggest that maintaining weight loss through diet and/or exercise can lead to long-term reductions in angiogenic factors, which may have implications for cancer prevention and treatment.
What is the benefits of superset method in resistance training?5 answersThe superset method in resistance training has several benefits. It has been shown to enhance muscular endurance, as observed in the bench press and barbell curl exercises. Additionally, superset training can provide a time-efficient strategy to achieve adaptations in muscle mass. It has also been found to increase training volume and total work, making it an effective method for increasing overall training intensity. Furthermore, superset training can lead to greater metabolic stress and muscle fatigue, which can contribute to muscle growth and development. Studies have also shown that superset training can reduce fat mass and increase muscle mass. Overall, the superset method in resistance training offers benefits such as improved muscular endurance, time efficiency, increased training intensity, and potential for muscle growth and fat loss.
