Q: Are there any supplements i should be taking along with the diet and exercise ?

A: I wouldn't take any supplements. They're generally overhyped, overpriced, and many have nasty side-effects. Here's my answer to the same question from six years ago and nothing has changed since then: http://www.mikesfitness.com/content/diet-pills

Coffee is good "supp" for a little extra fat-burning and energy for workouts. You could also use plain whey protein powder if you are having trouble getting enough protein in your diet from everyday foods; but I wouldn't consider protein powder a supp -- it's really just a food.
