It's all about calories.@Daywalker - Low-fat/fat free foods, especially the dairy type are a huge trap. Stuff like "I can't believe it's not butter" seem to be healthy on the surface but you are often times much better served eating full fat butter, milk, cheese and etc. Fat-free products are extremely processed (how the #### do you make butter fat free?), less satiating and can be counter-productive when said products would instead be providing you with the healthy, monosaturated fats that lead to a leaner waste. Even saturated fats aren't bad for you when eaten in moderation.
Eating five pieces of toast with I can't believe it's not butter and sugar free strawberry preserve at 250 calories fills me up. Satiated.
