The diets are aimed at people who usually eat badly; too much processed carbohydrates, sugar and ready meals and not sufficient fruit and veg.
However odd or quirky they sound and of course the quirkier they are the more people sign up for them. All these diets do is break the cycle of a poor diet to move people to a healthier eating pattern - and of course they feel the benefit. But if they then return to their previous poor eating habits the advantage will have gone in a week.
It is boring but 'Eat well, not too much, most of it plants' - and avoid processed food and you will not need to read these diet of the day articles which are more to titillate the interest of those feeling guilty because they eat badly and get a virtue rush when they try another quirky diet promising health benefits.
Most of us have items of food that do not agree with us and other food items we really dislike. Fresh milk and yoghourt make me nauseous and worse, and I truly loathe goats cheese, while loving cow and sheep's cheese. I doubt any diet whether it 'rests my gut', 'detoxs my digestion' or whatever the current promise is, will alter that.
