Impact of a walking program of 10,000 steps per day and dietary counseling on health-related quality of life, energy expenditure and anthropometric parameters in obese subjects.
Study Goal
The researchers aimed to assess the impact of a physical activity program (10,000 steps/day) combined with monthly dietary counseling on body composition, biological parameters, resting energy expenditure, and health-related quality of life in obese individuals.
Results Summary
The intervention significantly improved anthropometric data (e.g., reduced body mass, BMI, fat mass), increased resting energy expenditure, and enhanced physical domains of health-related quality of life and anxiety. No significant changes were observed in biological parameters.
Population
35 obese adults (26 women; mean age 39.2 ± 13.4 years, mean BMI 38.3 ± 6.6 kg/m²).
Effective Dosage
Qualitative dietary advice (cookbook with low-calorie recipes and dietary advice) provided monthly.
Duration
6 months.
Interactions
None mentioned.

PURPOSE: The aim of this pilot study was to assess the impact of a physical activity program of walking 10,000 steps per day along with monthly dietary counseling on the body composition, biological parameters, resting energy expenditure (REE) and health-related quality of life (HRQoL) of obese individuals. METHODS: Thirty-five obese adults (26 women; age: 39.2 ± 13.4 years, body mass, BM: 104.1 ± 18.7 kg and body mass index, BMI: 38.3 ± 6.6 kg m-2) followed a walking program (instructions were provided so that the participants increase their walking distance by 1000 steps each week, until to perform at least 10,000 steps per day) and received qualitative dietary advice (cookbook presenting numerous recipes with low calories and dietary advices was provided) for 6 months. Before and after the intervention, anthropometric (BM, BMI, waist and hip circumferences, fat mass: FM and lean body mass: LBM) and biological data (total cholesterol, high-density lipoprotein, low-density lipoprotein, triglyceride and glucose concentrations), REE and HRQoL (including eight dimensions and two summaries) were assessed. RESULTS: After the intervention, BM (difference: 3.8 kg or 3.7 %), BMI (difference: 1.4 kg m-2 or 3.7 %), hip circumference (difference: 4.6 cm or 4.3 %), FM in kg (difference: 4.0 kg or 8.9 %) and FM in percentage of BM (difference: 1.6 kg or 6.1 %) were significantly decreased, whereas number of steps (difference: 7579 steps or 135 %), LBM in percentage of BM (difference: 2.6 kg or 4.5 %) and REE (difference: 78 kcal d-1 or 4.8 %) were significantly increased (p < 0.05). Moreover, two HRQoL subdimension scores (physical functioning and physical component summary; increase by 15.3 and 4.6, respectively, p < 0.05) and anxiety (reduction by 1.2, p < 0.05) were also significantly improved. Conversely, the biological data showed no significant change (p > 0.05). CONCLUSION: Walking 10,000 steps per day in association with dietary counseling improved anthropometric data, REE, the physical domains of HRQoL and anxiety in obese adults.
