Healthy measures: Feasibility study of a moderate carbohydrate weight management intervention.

ABSTRACT

BACKGROUND: People of all weights need to prevent changes that could lead to obesity, a leading public health issue. OBJECTIVE: To assess the feasibility of Healthy Measures, a moderate carbohydrate (160-300 g/d) nutrition education and behavioral intervention. DESIGN: An uncontrolled intervention feasibility study including in-person group meetings every 2 weeks for 3 months. SAMPLE Fifteen participants of normal and overweight BMI. MEASUREMENTS We assessed feasibility of recruitment, attendance, retention and satisfaction as well as anthropometric measures and social cognitive variables with Healthy Measures, a nutrition-focused intervention with moderate carbohydrate portions that also emphasizes self-monitoring of anthropometric measurements. An intent-to-treat analysis was used. RESULTS: Healthy Measures was feasible, with 13 participants (86.7%) completing pre- and post-intervention assessments. Eight participants lost or maintained weight (53.3%); four gained weight. Healthy eating self-efficacy increased overall (t = -2.54, p = .024). Increased protein and fat intake was associated with weight loss, while reduced protein, carbohydrate, and fat intake resulted in weight gain. CONCLUSIONS: Healthy Measures shows promise for prevention of weight gain, with evidence of feasibility and positive outcomes. Further research is needed to establish efficacy relative to alternative approaches.
