RESUMO
Objective To discuss the effects of different exercise frequency and diet guidance for fat loss on obese patients, and to develop a safe and effective multidisciplinary intervention program for obese patients. Methods A total of 140 members of Ningbo Slimming Club were recruited, with the age between 18-60 years, body mass index (BMI) greater than 28 kg/m2, and they were randomly assigned to low frequency group and high frequency group. In low frequency group, the intervention was complete 100 minutes aerobic exercise and 3 times a week. In high frequency group, the intervention was complete 50 minutes of aerobic exercise and 6 times a week. Each group followed the same diet weight loss program. By comparing each index before and after the intervention, the effect of fat loss was evaluated. Results After intervention, systolic blood pressure, diastolic blood pressure, body weight, BMI, waist circumference, body fat percentage, triglyceride, low density lipoprotein and total cholesterol in two groups were decreased, and high density lipoprotein were increased (P<0.05) . Compared between the low frequency and high frequency exercise group, there were no significant difference for the systolic blood pressure, diastolic blood pressure, body weight, waist circumference, BMI, triglyceride, high density lipoprotein, low density lipoprotein and total cholesterol levels (P>0.05), but body fat percentage in low frequency exercise group decreased significantly (P< 0.05) . Conclusion Diet intervention combined with exercise has a significant effect of fat loss on obese patients. Based on the same weekly aerobic exercise time, obese patients with low frequency of exercise had better fat loss than obese patients with high frequency of exercise.
