I’ve recently been playing around with a ketogenic diet, and it had an unexpected impact on my skin: I am the clearest I have been since I can remember.
The diet I am on is about 300 grams of fat/day, 200 grams of protein, and 20 grams of carbs. I am a 6’2, 195 pound extremely active male; these numbers should be decreased for most people but the ratios can stay the same.
Given everything written on this site, and the large number of studies showing that sugar consumption leads to acne, it is not surprising that an extremely low carb diet leads to better skin.
I plan to do further experimentation on the fat/protein ratios; I suspect that the primary reason this diet works is simply that carbohydrates cause acne, but there may be something to the high fat / medium protein intake as well.
Some keto friendly foods are: macademia nuts, walnuts, coconut oil, olive oil, chicken, steak, ghee, and the other usual suspects. You may notice that they are similar to the “acne friendly” foods you will see written about elsewhere. Note: cheese is a popular keto-friendly food, but dairy will trigger acne in many people.
