Lowering you carbohydrates will decrease the vascularity in many. The hormone insulin, necessary to partition carbohydrates from the blood to muscles, brain, fat, wherever, has a vasodialtive effect and will expand blood vessels and bring out vascularity. You'll notice the most vascularity after a meal that is pretty much simple sugar (such as desert, candy, etc) because the insulinogenic effect is greatest. Hope this helps you! As you lose fat, you will notice vascularity more and more and if it's really important to you, I'm sure a good nitric oxide product may be worth it. Once you achieve your goals, maybe you can incorporate more carbohydrates into your diet and utilize some Na-R-ALA before the carb containing meals. Na-R-ALA gives roadmap vascularity with continued daily use as well. It helps me take in more carbs without getting fat.
