low carb will melt fat like nothing else but it comes with a price, MUSCLE LOSS, unless you're on gear.. My approach is carb cycling, nothing even compares to it in terms of fat loss and maintaining or even gaining muscle, with carb cycling your body will not get used to insulin, so your insulin sensitivity will be high since you cycle carbs, its very effective but its hard to keep up with, and you have to be very accurate or else it wont work.
