If an obese person attempts to lose weight and starts eating healthy, would the plaque on their arteries decrease and/or disappear over time?

I'm not obese myself, I'm just wondering.

Point of clarification, just being obese doesn't mean that there are plaques in arteries (arteriosclerosis). Being obese only raises the risk for developing plaques. 

That said, a healthier diet and weight loss in a person that does have plaques can slowly decrease the natural progression of the plaques.
