I love pizza. It somehow fills all the other voids in my life...sigh. Anyway when you get your pizza grab a side salad. Drink a large glass of water and slowly eat your salad with whatever dressing you like. This kills that shark attack first hunger kind of munching. Then sit back and nom your pizza. If you eat it all, great you were hungry. If you don't even better, it lasts 3 days in the fridge. I love Caesar salads the most, got that whole cheese on toast celebration thing going on. Cheese is psychologically addictive it releases a feel good chemical in your brain. ( L-Tyrosine supplement can help overcome this ) The other thing is it could be a sign of calcium deficiency as your body craves what, it thinks, gives it what it needs. ( pop a calcium supplement or eat more leafy greens/chickpeas ) Hope some of that is useful

Pizza is also my Kryptonite, along with cake, burgers, kebabs, pies, biscuits, chocolate and pop

Oh and ice cream. Have fun and good luck.
( Goodfellas do a low fat low calorie pizza that's not too bad ) Littlefellas chicken pizza, 325cals ish and 5.6g of fat per pizza although for more fun make your own.
