I admit it: I used tomato paste for my sandwiches instead of butter, because it was low fat. No butter. how sad. 
Do you remember 0.1% fat yogurt? No matter how much ground vanilla or cinnamon you threw in there, it still tasted like nothing.
Or dried fruit, because it’s a “healthy snack”. Who decided that dried fruit is healthy (and acceptable as a treat?).
This kept the wheel spinning on and on and worsened my wrong eating patterns.
Another one: low fat sausage! Unreasonably expensive and full of crap. They sticked to the pan, so you had to cook them in water. The heated thing only tasted like the Ketchup you needed to have with it.
