RESUMEN
This study compared treatment outcomes for a new weight loss program that emphasized reducing unhealthy relationships with food, body image dissatisfaction, and internalized weight bias (New Perspectives) to a weight loss program that emphasizes environmental modification and habit formation and disruption (Transforming Your Life). Fifty-nine overweight and obese adults (body mass index ≥ 27 kg/m(2)) were randomly assigned to either a 12-week New Perspectives or Transforming Your Life intervention. Despite equivalent outcomes at the end of treatment, the Transforming Your Life participants were significantly more effective at maintaining their weight loss than New Perspectives participants during the 6-month no-treatment follow-up period.

BACKGROUND: In a stepped-down approach, patients begin with a more intensive treatment and are stepped down to a less intensive treatment based on achieving treatment goals. This study compared a standard behavioural weight loss programme (BWLP) to a stepped-down approach to treatment. METHODS: Fifty-two overweight/obese adults (Age: M = 47 years, SD = 13.5; female = 67%) participated in an 18-week BWLP. Half of them were randomly assigned to be stepped down from weekly group meetings based on completion of weight loss goals (3%) every 6 weeks, while the other half remained in their groups regardless of weight loss. RESULTS: There was a significant difference favouring the BWLP in the proportion of participants who met or exceeded their 3% weight loss goal during the first six weeks. While not statistically significant by the end of treatment, the BWLP participants lost nearly 3% more body weight than stepped-down participants (SC = 4.9% vs. BWLP = 7.8%; p = .10). Greater self-monitoring was associated with increased likelihood of stepped-care eligibility and higher percent weight loss at the end of treatment (p < .01). CONCLUSION: There was little evidence to support the efficacy of the stepped-down approach for behavioural weight loss treatment employed in this investigation.
