CLA could be promising. For example, I was reading this study, which showed that:
"The addition of a thermogenic, CLA, protein, and a multi-vitamin to a three-week low-calorie diet improved weight loss, total fat loss and subcutaneous fat loss, compared to diet alone."

Anyone try it? What was your experience?
