And rogen rise is greater in those patients who lose more weight as well as in younger , non-diabetic subjects with a greater degree of obesity .
Body weight loss is also associated with a decrease in estradiol and an increase in gonadotropins levels .
These data show that weight loss is associated with an increase in both bound and unbound testosterone levels .
The normalization of sex hormones induced by body weight loss is a possible mechanism contributing to the beneficial effects of surgery in morbid obesity
OBJECTIVE Few r and omized clinical studies have evaluated the impact of diet and physical activity on testosterone levels in obese men with conflicting results .
Conversely , studies on bariatric surgery in men generally have shown an increase in testosterone levels .
The aim of this study is to perform a systematic review and meta- analysis of available trials on the effect of body weight loss on sex hormones levels .
Influence of exercise training on physiological and performance changes with weight loss in men.
PURPOSE The purpose of this study was to examine the physiological effects of a weight-loss dietary regimen with or without exercise . METHODS Thirty-five overweight men were matched and r and omly placed into either a control group ( C ; N = 6 ) or one of three dietary groups ; a diet-only group ( D ; N = 8) , a diet group that performed aerobic exercise three times per week ( DE ; N = 11 ) ; and a diet group that performed both aerobic and strength training three times per week ( DES ; N = 10 ) . RESULTS After 12 wk , D , DE , and DES demonstrated a similar and significant ( P < or = 0.05 ) reduction in body mass ( -9.64 , -8.99 , and -9.90 kg , respectively ) with fat mass comprising 69 , 78 , and 97 % of the total loss in body mass , respectively . The diet-only group also demonstrated a significant reduction in fat-free mass . Maximum strength , as determined by 1-RM testing in the bench press and squat exercise was significantly increased for DES in both the bench press ( + 19.6 % ) and squat exercise ( + 32.6 % ) . Absolute peak O2 consumption was significantly elevated in DE ( + 24.8 % ) and DES ( + 15.4 % ) . There were no differences in performance during a 30-s Wingate test for the DE and DES , whereas D demonstrated a significant decline in peak and mean power output . Resting metabolic rate ( RMR ) ( kcal x d(-1 ) ) was not significantly different for any of the groups except for the DE group . There were no significant changes in basal concentrations of serum glucose , BUN , cortisol , testosterone , and high density lipoprotein ( HDL ) cholesterol for any of the groups . Serum total cholesterol and low density lipoprotein ( LDL ) cholesterol were significantly decreased for all dietary groups . Serum triglycerides were significantly reduced for D and DES at week 6 and remained lower at week 12 for D , while triglycerides returned to baseline values for DES . CONCLUSIONS These data indicate that a weight-loss dietary regimen in conjunction with aerobic and resistance exercise prevents the normal decline in fat-free mass and muscular power and augments body composition , maximal strength , and maximum oxygen consumption compared with weight-loss induced by diet alone
