I usually eat alot of food, most of it healthy, some of it not so (but nothing that is terrible for you).
My skin is pretty much clear but I still get a bit of mild acne here and there depending on my diet.
However, the sport that I do requires me to stay within certain weight limits, so whenever I have a competition coming up I end up reducing my food intake drastically, I'll eat enough to keep my body going and to get all the right nutrients I need but compared to my usual diet its much much less calories.....mainly coming from vegetables, with a small amount of grain based carbs to keep my body fuelled.
Ive noticed that everytime I do this, my skin pretty much goes perfectly clear, my mild acne clears right up, its like magic! And it starts to kick in after about 4 or 5 days of the reduced calorie diet.
Just thought I'd throw this one out there! Like I say I usually eat healthy anyhow, but I just consume ALOT of calories, and although my skin doesnt trouble me too much its enough to give me mild acne, sometimes slightly moderate depending on how much Ive eaten.
But just to reiterate, everytime I go on this reduced calorie diet, I literally clear up 100%, granted I avoid my food intolerances of course, which I do anyway.
Hope this helps anyone out there who is wondering. I guess its not much use if you are trying to gain weight though!
