Exercise , particularly aerobic exercise , had a significant effect on serum leptin and a possible influence on adiponectin levels , suggesting its therapeutic implication
Previous reports have shown that exercise improves serum leptin and adiponectin abnormalities in overweight and obese individuals ; however , results to date are controversial .
Here we performed a systematic review and meta- analysis of the available r and omized controlled trials ( RCTs ) of the possible beneficial action of exercise on serum leptin and adiponectin levels in overweight and obese individuals .
Changes in Children’s Sleep Duration on Food Intake, Weight, and Leptin
OBJECTIVE : To examine the effect of experimental changes in  children ’s sleep duration on self-reported food intake , food reinforcement , appetite-regulating hormones , and measured weight . METHODS : Using a within-subjects , counterbalanced , crossover design , 37 children , 8 to 11 years of age ( 27 % overweight/obese ) completed a 3-week study . Children slept their typical amount at home for 1 week and were then r and omized to either increase or decrease their time in bed by 1.5 hours per night for 1 week , completing the alternate schedule on the third week . Primary outcomes were dietary intake as assessed by 24-hour dietary recalls , food reinforcement ( ie , points earned for a food reward ) , and fasting leptin and ghrelin . The secondary outcome was child weight . RESULTS : Participants achieved a 2 hour , 21 minute difference in the actigraph defined sleep period time between the increase and decrease sleep conditions ( P < .001 ) . Compared with the decrease sleep condition , during the increase condition , children reported consuming an average of 134 kcal/day less ( P < .05 ) , and exhibited lower fasting morning leptin values ( P < .05 ) . Measured weights were 0.22 kg lower during the increase sleep than the decrease sleep condition ( P < .001 ) . There were no differences in food reinforcement or in fasting ghrelin . CONCLUSIONS : Compared with decreased sleep , increased sleep duration in school-age children result ed in lower reported food intake , lower fasting leptin levels , and lower weight . The potential role of sleep duration in pediatric obesity prevention and treatment warrants further study
