Interventions/Control_1

Control Group:
- Weight Loss Diet and No Supplementation or Exercise

Interventions/Control_2

Intervention Group 1 (CLA Supplementation):
- Weight Loss Diet
- Mixture of the two bioactive isomers in the form of a 1500 mg softgel -50% cis-9, trans-11 and 50% trans-10, cis-12- twice a day for 12 weeks

Interventions/Control_3

Intervention Group 2 (CLA Supplementation + Exercise):
- Weight Loss Diet
- Mixture of the two bioactive isomers in the form of a 1500 mg softgel -50% cis-9, trans-11 and 50% trans-10, cis-12- twice a day for 12 weeks
- Exercise as walking with the speed of 5.5-6 km/h for at least 160 minutes per week which the subjects had the choice to spare it into three or four times a week. Subjects kept track of walking speed and distance using treadmill or software installed on their cellphone, and recorded their exercise activity and provided it to the dietitian at each visit

Results

171 subjects completed their participation (Response Rate = 95%), and in comparison with the baseline body weight, Body Mass Index (BMI), Body Fat Mass (BFM), and waist to hip ratio of the CLA and CLA+E groups had a significant decrease (P < 0.05) with average BFM loss being 10.3% and 12% among CLA and CLA+E, respectively, compared to 2.7% among Control group. As for the biochemical analysis, the blood free fatty acid increased and high density lipoprotein decreased in CLA group which was an unfavorable effect of CLA supplementation. Although the supplementation alone appeared to have some non-desirable effects on the mentioned blood tests, this change did not occur among the exercise group.

As a conclusion, supplementation with conjugated linoleic acid among overweight Iranians for 12 weeks reduced the BFM with some adverse effects on blood profiles which can be controlled through a moderate-intense exercise.
