Unfortunately, the more we think about food, the more we want to eat it. No, it's not weakness. We are programmed to see food and want to eat it. It's a survival mechanism sewn into our DNA so that we don't starve in times of food scarcity. When food was actually scarce, this ability to eat anytime was probably a lifesaver, but now, everywhere we look food is calling to us saying EAT ME, EAT ME.
