The problem with Chex Mix is that although it may contain 60% less fat than potato chips, it still contains fat, and is still not the most healthy food around.
Back in the day (college), I was way more strict with myself about food. I wouldn't buy chips (although I did go through a pita chip phase during grad school). I would limit myself to one sweet thing a day. This lasted until a very stressful phase in grad school where I dropped to 124 lbs., and my doctor commanded me to eat more per day (this is when the pita chip obsession began - also my love of bagels with a TON of cream cheese on them). I ended up gaining back the weight, due to my wonderful husband's love, not the food. But I never went back to my strict policies with myself.
Which is unfortunate, because, while at a game night two weekends ago, the hosts offered us Chex Mix. Never before have I enjoyed Chex Mix so much. And now a bag of it is sitting in the pantry, calling to me, singing me its siren snacking song.
