LONDON, England -- Forget what the bride will wear or who the guest list may include, the new buzz about Kate Middleton and Prince William's wedding is the diet.
Both Kate and her mother are reportedly on The Royal Diet which has been taken by storm on this side of the pond thanks to a new book.
The Dukan Diet by Dr. Pierre Dukan is yet another carb-hating protein-loving weight-loss plan. And plenty of American women are trying it. The book hit shelves on the April 19 and jumped to the top position on Amazon.com's Top 100 Bestseller List the next day.
Anything that the royals do, other people want to do. And it turns out that s not just limited to fashion, it includes diet fads, said Providence cardiologist Dr, James Beckerman. Beckerman is the author of his own diet book, The Flex Diet-. He notes everyone should be skeptical of a quick fix.
Any calorie restriction will work well initially, but it s a question of how you maintain it, Beckerman said.
The diet, broken down into four phases, promises you'll lose seven to 10 pounds in the first week:
Phase one: Attack Phase
Similar to the Atkins Diet, you stick to lean protein like chicken, lean beef, and seafood for the first week. Oat bran and low-fat cottage cheese are your only reprieve.
Phase Two: Cruise Phase
Protein-only days are alternated with days of protein and veggies like lettuce, cucumbers, and tomatoes. On this stage you should lose about 2 pounds a week.
Phase Three: Consolidation Phase
Starts only when you've reached your goal weight. Now you are allowed one portion of fruit and two slices of whole-grain bread each day. Once a week, you can also have one serving of pasta.
Phase Four: Stabilization Phase
You can eat what you want as long as you have a protein-only day once a week.
If you limit yourself to lean protein, you consume less food overall and fewer calories overall, said Dr. Beckerman, who also points out it doesn't it doesn't mean it is healthy.
One thing that lean protein has is potentially a lot of sodium and not a lot of fiber, Dr. Beckerman said.
The French Health Administration slammed the diet for those exact reasons. And in Britain it was named one of the top 5 worst diets of the year.
It just doesn t seem like a diet that s geared towards making people healthier. It's just towards people losing a lot of weight in a few days. Research shows that people who yo yo diet, who lose a lot of weight suddenly, tend to gain all of it back, plus extra, he points out.
The diet also includes drinking lots and lots of water and exercise.
