Your derm sounds amazing. I guess it's where I live, but all of mine push "safe" tanning and shit since I'm so pale.   I will never be able to understand fat logic. I was raised in a house with a shitty mentality about food, but I'm no fucking fool so I figured shit out on my own. It isn't hard. Nearly everything has calories. If you're not sure, look it up. There's no excuse with modern tech.
