"Am i the only one who doesnt understand it?"
The issue is that those things there that you've mentioned aren't how it works...so, um, yes you don't understand it.
It makes perfect nutritional sense, it's a low calorie, low fat eating plan.
1/3 of every portion should be very low calorie veg or fruit...and you're supposed to eat until you're comfortably full. So it's not unlimited pasta, it's 1/3 of a plate of veg, preferably some sort of protein and your carbs, until you're full, paying attention to you being full and the veg control the portion size.
Muller lights are only unlimited if they're of a similar calorie content (and fat and sugar) as plain zero fat yoghurt and fruit - and technically they're not unlimited as again, you ideally want to be having something with it (fruits like raspberries or melon rather than veg) and again paying attention to how much actually satisfies you.
Smash is rank and easily avoided, but if you want to eat that instead of actual potatoes, again, it's similar in calorie content to potatoes and part of a filling meal.
Oh and it'd work fine for you because you can't skip meals and eat junk very well while you're following it, I know that because that was why I was overweight.
The basis of it is that you're eating lean protein, fresh fruit, veg and carbs then limited amounts of bread, milk or cheese and small amounts of the high calorie not filling stuff.
