Pizza describes /hides a multitude of sins.
Pizza is not one thing.
For instance, I only have thin n crisy, as I just can't manage all the dough on any others. I only choose those that I can see actual tomatoes on (so not processed), and generally if I want pepperoni type meat, I will slice my own and add sufficient, as I do tend to avoid heavy meat products with nitrates sulphates in.
That's not me denying myself, I really don't like all the other overly fatty and doughy stuff. Is this what you mean cleomummy ?
It's my habit, if you like,. I like the fresh taste of the tomatoes and unprocessed foods, so it might have spinach and basil and mozzarella.
It won't have any of those processed chicken, spicy beef, or anything on. That discounts a lot of pizzas from my options.
I also think its possible to alter your tastes, and switch off your natural stop valve, or increase your tolerance for fats and stodge, through over-eating a lot, which also expands your stomach. I did this at Christmas, and it was horrible, I just felt so uncomfortable for so long. To get morbidly obese I would consider it would be necessary to continue to ignore my capacity as the sheer volume that I've seen very overweight people eat, and the type of food, turns my stomach and I find it really off-putting.
I don't eat burgers for instance, don't keep a selection of biscuits or crisps or chocolates in. They are just not part of my daily life, or part of my normal shopping. From what I've seen around me, that's certainly not always the case.
I don't really eat pies, or pastry things.
Different lifestyles I think. I would be morbidly obese if I liked burgers and chips I think, but I don't. If I buy fish, I can't manage chips as well, its too much to eat for me.
