Walking, Spontaneous Physical Activity and Lipid Oxidation After Dietary Treatment of Obesity

Influence of Walking on Spontaneous Physical Activity and on Lipid Oxidation Following Dietary Treatment of Obesity

The purpose of this study is to determine whether walking exercise after dietary treatment of obesity is associated with a decrease of the daily spontaneous physical activity and\or with an increase of the time spent in sedentary activities. Our hypothesis is that the practice of walking as an exercise during the phase of weight stability following the dietary treatment of obesity leads to a reduction of spontaneous physical activity and\or to an increase in the time spent in sedentary activities.

The subjects of this study will be randomised in 2 groups:

A group with usual follow-up and a group with usual follow-up associated with recommendations to introduce a program of walking achieving gradually 2000-2500 kcal/week.

Inclusion Criteria:

• Women from 18 to 50 year-old
• In phase of weight stability
• BMI<40kg/m²

Exclusion Criteria:

• History of bariatric surgery
• Diabetes
• Suspicion of obstructive sleep apnea syndrome
