Programs that had professionals frequently interact with participants , regardless if the interactions were done daily , weekly , or monthly , led to a change in body composition .
Additionally , programs that incorporated a motivation theory and provided content relevant to participants ' needs result ed in a change in body composition .
Conclusion Evidence supports that future worksite wellness programs that are design ed using a motivational theory and content that is created relevant to participants ' needs and that has frequent interactions with participants may result in a change in body composition
Background Adult obesity is globally recognized as a public health concern .
As adults spend most of their weekdays at work , worksite wellness programs may include topics of nutrition education and physical activity to improve an employee 's body composition .
However , results are inconsistent with the impact they have on employees ' body composition .
Objective The purpose of this systematic review was to evaluate  worksite wellness nutrition and physical activity programs and their subsequent impact on participants ' body composition .
Eight-Year Weight Losses with an Intensive Lifestyle Intervention: The Look AHEAD Study
Objective To evaluate 8-year weight losses achieved with intensive lifestyle intervention ( ILI ) in the Look AHEAD ( Action for Health in Diabetes ) study . Design and Methods Look AHEAD assessed the effects of intentional weight loss on cardiovascular morbidity and mortality in 5,145 overweight/obese adults with type 2 diabetes , r and omly assigned to ILI or usual care ( i.e. , diabetes support and education [ DSE ] ) .  The ILI provided comprehensive behavioral weight loss counseling over 8 years ; DSE participants received periodic group education only . Results All participants had the opportunity to complete 8 years of intervention before Look AHEAD was halted in September 2012 ; ≥88 % of both groups completed the 8-year outcomes assessment . ILI  and DSE participants  lost ( mean±SE ) 4.7±0.2 % and 2.1±0.2 % of initial weight , respectively ( p<0.001 ) at year 8 ; 50.3 % and 35.7 % , respectively , lost ≥5 % ( p<0.001 ) , and 26.9 % and 17.2 % , respectively , lost ≥10 % ( p<0.001 ) . Across the 8 years ILI participants , compared with DSE , reported greater practice of several key weight-control behaviors . These behaviors also distinguished ILI participants who lost ≥10 % and kept it off from those who lost but regained . Conclusions Look AHEAD ’s ILI produced clinical ly meaningful weight loss ( ≥5 % ) at year 8 in 50 % of patients with type 2 diabetes and can be used to manage other obesity-related co-morbid conditions .
