If by carb cycling you mean adjusting daily carbs based on activity levels, then I've had pretty good results with that. I go by "food as fuel," so if I'm just going to be around the house I stay away from simple starches as best I can. If I'm going to be doing some heavy lifting I might add some rice or other starch.
What I don't do is follow some complex bodybuilding carb cycling protocol. They won't help at this point and they're controversial even at elite bodybuilding levels - so I would stay away from them and focus on the basics.
1) eat real food - more vegetables, moderate meat, moderate fruits, less grains, less sugar, less vegetable oils.
2) exercise - moderate intensity cardio, sprinting, heavy lifting, dedicated stretching and mobility.
3) live - relax, de-stress, meditate.
