I don't think anyone can survive on celery and lettuce alone.
If anything, if they tried, after a while, they'll get so malnourished that their cravings are likely to go overboard, and get them into overeating mode, jsut as their bodies prepare for the starvation operiod and their metabolisam slows down.
But, let's stick to more realistic examples.
Extreme cases really don't do much to describe a general rule.
