I love potato chips, in fact it is probably my cryptonite...especially with a coffee truck that swings by the office 3x a day it is especially tempting. I love to make kale chips to curb the craving. For me it is the crunchy feeling that gets me, so kale chips satisfy that craving. Wash a bunch of kale, break into small pcs in a bowl, toss in a bit of olive oil enough to coat and sprinkle a bit of salt, himalayan sea salt if you have it. Bake at 350 until you start seeing them crisp and dry up - make sure they don't burn because it tastes bitter when they get too brown.
Also when I have cravings for ice cream, I have frozen fruits ready in the freezer and blend that with some yogurt and milk. I do add a dollop of vanilla frozen yogurt for texture but the shake is a much healthier alternative!
Hope that helps a bit
