Having probably seen hundreds of diet fads come and go, I remember my mother and grandmother going on low carb diets as far back as the sixties. And here we are forty years later: The Atkins Co filed for bankruptcy today. Twenty years ago I was taught that we need high carb diets - high in complex carbs, that is. Today the stores were pulling the Atkins book displays down and replacing them with "The Three Hour Diet" - one which my aunt and uncle were on at least ten years ago. And they have probably each gained 50 lbs since. Set point theory, which claimed a natural set point based on activity levels, seemed logical, but I haven't even heard this mentioned in at least a decade. I did hear of twist on Set Point Theory that claimed that we all have a genetic set point, and that many people are just fighting a natural condition when they try to lose weight. But, after spending billions, we find more diet foods, and a nation heavier than ever before. It leaves a person feeling that no one really has a clue how to control weight.
