In articles and write ups there is an argument for and against carbs when
following a workout plan and diet while hitting ones macros.

Though it seems that some recommend taking an approach where they consume
little to no carbs (as much as they realistically can) and others recommend 
balancing carbs and fats while keeping the intake of protein constant.

In the latter, either higher carbs and low fat or high fat and low carbs depending on the individuals preference.

Is it advantageous to completely cut out carbs or is the balanced approach best
for someone aiming to lose fat and build muscle over a 12 week exercise plan?
