The "paleo diet" -- which supposedly mimics what our caveman ancestors ate -- has become a new health craze. But many scientists doubt that this hunter-gatherer cuisine of meat, veggies and fruit is as healthy as advertised, or even historically correct.
There are a growing number of people dedicated to the world of healthy food and starvation diets. Sometimes they try to convince their fellow human beings to join them in their strict approach to eating, advising friends and partners to cut down on beer consumption or give up bratwurst.
But now Tom Jones has come to the rescue of lovers of hearty food. The singer ("It's Not Unusual") was once considered a sex symbol. But Jones, who is about 1.80 meters (5'11") tall, had put on weight over the years, reaching more than 100 kilograms (220 lbs.). When Jones decided that it was time to lose weight, he chose a decidedly masculine method. The singer adhered to the diet of people who lived in the Paleolithic Age, which meant eating primarily meat.
