Check out this article on MSN today: The exerpt I was most interested in: Dietitians have long recommended regular mealtimes for their patients. Satchidananda Panda, an assistant professor at the Salk Institute for Biological
Panda let one group of mice eat freely throughout the 24-hour day while another group was fed on a rigid schedule. The second group fasted for 16 hours a day, but both groups of mice ate the same amount of calories for two weeks. Then he did gene scans on the mice to see what was going on in their livers.
In the mice on the uncontrolled feeding schedules, food metabolism genes in the liver were chaotic because the mice were frequently eating and nibbling. Overall, nearly 3,000 liver genes involving in burning fat and sugar were expressed in the freely-eating mice throughout the day.
While it might seem advantageous to have thousands of calorie-burning genes running throughout the day, this makes metabolism less efficient and can create a byproduct that attacks and breaks down DNA, Panda says.
By contrast, the mice on a controlled feeding schedule had a much more consistent pattern of liver gene expression. When feeding, the mice burned sugar, but fat-burning didn't occur until several hours after they had begun fasting.
Anyway, just sharing. Happy Monday everyone!
