I am a recovering anorexic, and have been eating again for about two and a half months. I have been eating around 3500 calories a day, and I get about 100 grams of protein daily. I also eat a lot of fruits and veggies, and have been taking a vitamin. But after I shower, and I go to dry my legs, the tan color from my skin winds up on my towel. Do I still have a nutritional deficiency? There is also a possibility I have celiacs, and I have been trying to cut gluten. Could that cause it too? Any info would be great.
