Results Based on consistent evidence from studies that were rated as moderate or strong , there is good evidence that military weight management interventions are effective in improving body composition for duration s of up to 12 months .
Effective interventions are more likely to be high intensity ( have a greater number of sessions ) , are more often delivered by specialists , and use theoretical base/behavioral change techniques and a st and ardized guideline .
Dietary interventions can potentially reduce total fat and saturated fat intake .
Dietary interventions that target the kitchen staff and /or increase the availability of healthy food are more likely to be effective in the short term .
The results regarding military physical fitness interventions were inconclusive .
Conclusion Despite limitations such as the diversity and heterogeneity of the included interventions , outcome measurements , and follow-up duration , this systematic review found good evidence that weight management interventions are effective , especially in terms of weight loss .
Background Research has been conducted to assess the effectiveness of weight management , dietary and physical activity interventions in military setting s. However , a recent and comprehensive overview is lacking .
The aim of this systematic review is to examine the evidence and describe key components of effective interventions in terms of improving body composition , dietary behaviors , and physical activity among active-duty military personnel .
Efficacy of orlistat 60 mg on weight loss and body fat mass in US Army soldiers.
A higher body mass index is associated with exercise-related injuries and increased risk for musculoskeletal and connective tissue disorders , which are relevant to military personnel . Studies show the efficacy of orlistat 60 mg for promoting weight and body fat loss in civilians ; however , its efficacy among predominantly young , male soldiers is unknown . This study 's objective was to examine the effect of a 6-month , st and ard education-based weight-management program with and without orlistat 60 mg on changes in weight and body fat in overweight soldiers . Data were collected for this r and omized , controlled trial from March 2008 to November 2010 at Fort Bragg , NC . Participants were enrolled in an education-based weight management program ( n=435 ; 75 % men ) and were r and omized to placebo or orlistat 60 mg , three capsules daily with meals . All participants were recommended to maintain a reduced-energy , low-fat diet . Among study completers ( 14 % retention rate ; placebo n=22 , orlistat n=35 ) members of both groups lost significant weight from baseline  ( placebo -3.0±5.2 kg ; orlistat -3.2±4.7 kg ; P<0.01 ) , but only the orlistat group lost fat mass ( -2.5±3.9 kg ; P<0.001 ) , whereas the placebo group lost lean mass ( -1.4±2.7 kg ; P < 0.01 ) . An intent-to-treat analysis ( ? 1 follow-up body weight measure ) demonstrated that the orlistat group lost more fat mass vs the placebo group ( -1.3±2.9 kg vs ? 0.6±1.8 kg , respectively ; P<0.05 ) , but less lean mass ( -0.2±2.0 kg vs -0.8±1.8 kg , respectively ; P<0.01 ) . Orlistat 60 mg may be an effective adjunct to an education-based weight management program in a mostly young , male soldier population
