To assess the effectiveness of health literacyinterventions in achieving weight loss in adults withoverweight or obesity.

Studies were obtained from searches of 17 elec-tronic bibliographic databases, hand searching,relevant websites, and personal communication.

Intervention studies using experimental orquasi-experimental methods conducted in primaryhealthcare (PHC) or by a PHC professional outsidethe PHC setting with a minimum 6 months follow-up, published in the English language between1989 and June 2013 in one of the OECD membercountries. Studies where patients had any chronicdisease were excluded.

Three authors extracted data and one indepen-dently assessed trial quality.

Nineteen studies were included with 3747participants (71% females). Of these, 15 werepatient-focussed, one provider-focussed and threestudies addressed both. Three studies included ele-ments of functional, 15 of interactive and oneof critical health literacy. All targeted lifestyle(diet and physical activity). Fourteen studies wererandomised trials with nine showing significantbetween-group weight loss differences over aperiod of 6—12 month follow up. All five non-randomised trials showed significant weight lossesover a period of 6—18 month follow up.

Five studies included patients from a disadvan-taged background. Participants in 11 studies wereat a high risk of developing diabetes. Duration ofstudies was <6 month (5), 6—9 months (6) and >9months (8). The intervention was delivered indi-vidually (4), group sessions (9), mixed group andindividual (3), internet only (1), mixed telephoneand internet (1), and mixed telephone and individ-ual (1).

The intervention was delivered by diabetes edu-cators, dieticians, health promotion and internetcounsellors, lay leaders, medical practitioners,

nurses, physiotherapists, physical activity special-ists, psychologists, traditional wellness coordi-nators, and the Internet.

The results of this review show the effectivenessof a variety of health literacy-focussed lifestylemodification programs, incorporating physicalactivity and dietary changes, in achieving weightloss.

Context: A higher protein to carbohydrate ratioin the diet may potentiate weight loss, improvebody composition and cardiometabolic risk, includ-ing glucose homeostasis.

Objective: To determine the efficacy of twostructured lifestyle interventions, differing indietary protein and carbohydrate composition,on insulin sensitivity and body composition.We hypothesized that a moderate-carbohydrate,increased-protein diet would be more effective inimproving outcome measures in obese, insulin resis-tant adolescents.

Design: Randomised control trial, known asRESIST, in two hospitals in Sydney, Australia.
