A lot of those here who eat high carb (myself included) don't have weight to lose. I am a thin, active 23-year-old male. I have the most energy and feel best when I include lots of carbohydrate in my diet. I've been eating a paleo-ish diet for about 3 years, and I've made small tweaks and adjustments according to how I feel and what I can afford. The general consensus on things like white rice, sprouted grains, refined sugar, etc. is that they make viable options if they're helping you reach your goals and you have no negative side effects.
But dude, if low carb is helping you lose weight or reach your goals, do it until it no longer works for you. That could be 3 months, a year, or three years from now, or it might work for you indefinitely. If and when it does stop working, make tweaks to your diet/lifestyle until you're satisfied.
