Yes indeed, the egg diet.
One is always on a diet of some sort in this household
...... and they do work, more or less
. But whilst every diet is often successful the first time you do it, it's less so thereafter, I find, especially for ostriches.
What is interesting is that one of the most successful diets I've ever done was the 7-day GM (General Motors of America) diet, which involved at least one set day on nothing but bananas and milk
. Over the years, this has been roundly rubbished by nutritionists and dieticians, so on, as a quack diet .... however, it was interesting to see it heavily promoted in a Times supplement a couple of weeks back as the "go-to" diet of 2017 if you want to get your body toned up for the beach!
What goes around, comes around, I guess, especially if it's a fad ...
