potato chips ... never really cared for them, unhealthy, and not delicious, so don't eat at all now.
grilled cheese sandwich ... was the ONLY thing my little brother would eat for about 10 years ... got so sick of them by the time he was 4 years old that I vowed never to eat one again.
French Fries ... these things are tasty, but also horrible for me. I still eat them from time to time, but, I don't eat them on a regular basis, and I now stick to a smaller size... so my consumption is probably down about 90%
Pop ... I used to drink like 2-3 liters of mountain dew or RC cola daily. Now, I consume maybe 1 liter per 2 months. I like how they taste, and I like the caffeine, but just not worth it from a calorie perspective, and diet pop tastes like crap, so I stick to coffee/tea/water now. (no sugar, no cream!!! And not that garbage powdered 'tea' from a can with all kinds of sugar and other contaminants.)
