I expect it's because each one vies with the other to come out with some brand new theory or other about why we gain weight and why their diet plan is the only one to help us lose it. And the low fat, low calorie stuff has already been covered!
My problem with this new trend is that the diets all involve more counting and while basic maths was never a problem at school I don't want to use it at the dinner table to know what I can eat. And while counting calories is one thing (most of us are probably walking encyclopaedias by now with how many calories our usual choices contain) the new diets are so much more complex.
With the new diets we need to know carbohydrate counts and fat grams, GI index and all sorts. And sometimes it's not enough to have a straight count we have to work out our percentage of carbohydrates, proteins and fat (yes, follow one particular diet and you have to balance these at EVERY meal).
Somehow I think food was not meant to be eaten like this. It was meant to be enjoyed. Most of us know what is healthy and what is not. Most of us know we'd be better with an apple than a cream cake. Most of us know we need a good variety of all types of food to feel great.
The new diets will not last. More complex stuff will come along and it's sad because we could all lose weight with a few SIMPLE changes.
1. Make healthy choices for most of the food you eat
2. Vary your choices
3. Occasionally enjoy a small portion of whatever it is you love even if it's high in fat or sugar or whatever
4. Eat only when you're physically hungry
5. Stop when you're just satisfied, not stuffed
6. Fill half your plate at lunch and dinner with vegetables or salad, quarter carbs and a quarter protein.
If everyone who wanted to lose weight just followed these simple guidelines there would be many more successful dieters around and a lot less hassle in losing weight.
