Brief summary
The investigators examined feasibility and acceptability of a non-restrictive diet focused on increasing dietary fiber and lean protein for weight loss. Fifteen obese adults enrolled in a 12-week assessment which included 6 bi-weekly individual dietary counseling sessions to attain a daily goal of higher fiber (\>35 g/day) and lean protein (0.8 g per kilogram/day of individual's ideal body weight).
Detailed description
Participants were instructed to increase both their dietary fiber intake to 35 g/day and protein intake to 0.8 g per kilogram/day of their ideal body weight. Loss of 5% of their body weight are considered to achieve the weight-loss goal. The intervention included 6 bi-weekly, 30-minute individual dietary counseling sessions over 12-weeks. Behavioral strategies including self-monitoring, problem solving, goal setting, stimulus control, food substitution, and relapse prevention were taught to assist participants in meeting their fiber and protein goals.
Interventions
