I’ve always wondered this… Does diet affect acne?

I’m a firm believer that your outter appearance is a pretty solid indication of what you are putting IN your body. Not just because of the countless studies I’ve read, but also through personal experience. I used to break out frequently and my hair was lackluster and wouldn’t grow. Once I started eating clean (lots of fish, veggies, healthy fats and complex carbs) and drinking a gallon of water a day, my skin cleared up and started glowing. My hair started getting compliments on its shininess! Besides also incorporating exercise, there really wasn’t much else that changed… so I attributed these improvements to my new eating habits. 
So back to the original question… “does diet affect acne?”

“Some say yes, others say no. A recent study found an improvement in acne when the men studied ate a low glycemic load diet. This means they ate a reasonable amount of protein and less high GI carbohydrate. The carbs they did eat were lower GI, so included more whole grains, pasta and fruit. The theory is that eating lots of white bread, cakes, refined cereal and other high GI foods increases insulin levels, which increases androgen (a male hormone) availability, which stimulates sebum production. So if you want the best skin you can, ditch the refined cereals and choose more whole grains, and fill up on vegetables and fruits rather than cake.”
