100 calorie packs have their place. But if your choice happens to be a food trigger, eating a 100 calorie pack will likely lead to a binge and you eating multiple 100 calorie packs.
The best use, imo, of 100 calorie packs is to meet a need using a non-triger food.
Say you have a sweet tooth, need a sweet treat daily mid-afternoon. Here's where your 100 calorie non-trigger food can do a world of good.
I almost always desire something sweet after lunch. Enter the Hostess Cupcake 100 calorie pack. Three miniature Hostess cakes plus a cup of Earl Grey with splash of skim milk. Totally satisfying.
Because Hostess cupcakes are not a trigger food for me I am not tempted to eat beyond one pack. As a plus the Hostess 100 calorie packs have a good bit of fiber--4 grams--which is a benefit to stave off hunger.
100 calorie packs can be your friend or a foe. Choose wisely.
