Behavior modification in the treatment of obesity.

Seventy obese subjects with a body mass index greater than 25 kg/m2 received a behavioral modification and a daily log self management program for weight loss during an 8-wk treatment period. The program included eating habits, exercise, attitudes, social relationships and nutrition. The results indicated that after 8 wks, cumulative weight loss (mean +/- SEM) was 4.3 +/- 0.4 kgs. The decrease in their body weight was due to the loss of their fat store evidenced by the significant decrease in triceps skinfold thickness. (P < 0.0001) The subjects showed significant decrease in total calories, carbohydrate and fat after 4 wks (P < 0.001, 0.001, and 0.008) through 8 wks (P < 0.007, 0.013 and 0.015). The activities in daily life changed significantly from rest level to light exercise level (P < 0.001). It was concluded that behavior modification program for short term showed improved eating habits and daily exercise. But we need time in order to identify variables responsible for maintenance of weight loss over the long term.
