I have 2 weaknesses when it comes to food, brownies and potato chips!!
If brownies are in the room, I can't resist, AND I can't just eat one! I will actually eat them for breakfast, lunch and dinner until they are gone.
Potato chips are a bit different. As long as I don't try one, I CAN resist them. However, once I take that first bite, I keep going back for more. The hot spicy chips are my favorite.
The key to avoiding my food trap is simply NOT to have them in my house! If I don't have access to it, I can't eat it. What is your food weakness?
