May face ultimate defeat,
When their attempts to limit meals
Succumb to culinary zeal.
But now scientists at CalTech
Have discovered, quite by chance,
A bunch of neurons, just a speck,
That dieters' goals may advance:
In the amigdala, in the brain,
When subjected to pure blue light,
A group of neurons is contained
That suppress the appetite.
So far, it only works with mice,
But if 't is effective for Man's mind,
Wouldn't it be very nice?
But what if one is color blind?...
