mono saturated and mono unsaturated fats are healthy, but they have to be done in balance. A smaller amount of poly unsaturated or poly saturated fats might be fine. I heard too much poly unsaturated fats could cause cancer. Too much poly unsaturated fats cause havoc on my body and cause weight loss. Healthy fats have a combination of different types of saturated and unsaturated fats. Really, its about balance.

Trans/hydrogenated fats are always to be avoided no matter what the goal is.
