Gwyneth's on 5:2 regime, so maybe it will work for me
Today is D-Day for me. Diet day, death of the purge day, call it what you will. After years of fighting fad diets and fending off all food trends, I've decided to cave in and try the 5:2 diet.
For a variety of reasons, this seems to be the most appealing one to hit mainstream markets in the last decade, and the fact that Gwyneth Paltrow, who was recently voted the Most Beautiful Woman in the World, is also said to be a fan only underscores my dedication.
I'm 5'8" and a size 12, making me 'normal' for my build. I don't need to lose weight, but my figure is a little more Marilyn Monroe than Miranda Kerr.
The 5:2 diet sounds rather reasonable. For five days, you eat as normal. In my case, I'll consume the recommended 2,000 calories daily as set out by the World Health Organisation (WHO). Then, for 48 hours, I will be taking part in 'fast days', restricting my calorie intake to just 500.
Why would I endure a life of feast and famine? Other than a willingness to try anything once, the reported benefits, including reducing the risk of heart disease and cancer, appeal to me more than simply dropping a dress size.
While I'm lucky that I've been blessed with strong will power, I have a debilitating condition called laziness.
I work in an unpredictable work environment, meaning that fitting in three consistent meals, all of which are packed with essential nutrients, is a challenge at the best of times.
There are online and in-person support groups for dieters who need a pick-me-up on their fast days. And I feel that if it's good enough for the most beautiful woman in the world, it's certainly worth a shot.
