Fortunately, they aren't part of my diet. My diet is actually quite simple. I eat just "whole" foods. Basically just meat, fish, vegetables, fruits and nuts. For breakfast, I have a couple of hard boiled (sometimes fried) eggs. For lunch, I have a tin of sardines packed in olive oil or a banana. Dinner is pretty much whatever I want, so long as the food is "whole" and not processed junk. Since April 1, I haven't had any junk food or fast food whatsoever.
In addition to that, I walk everyday and like the article above states, I use a pedometer to ensure I walk 10,000 steps a day. In fact, I usually do 15,000 to 20,000 steps a day which amounts to 7-10 miles. I walk three miles every morning around my neighborhood at 5AM. Then I walk 4 miles during my lunch hour. These two walks supercharge my metabolism and is probably the biggest contributing factor in my weight loss. On weekends or other days when I don't have to work, I do one super long walk of at least 6-8 miles. In fact, I did a 10 mile walk yesterday morning.
As one who has been overweight for some 20 years, I don't buy the excuses everybody else has for being overweight. It's all about calories burned and calories taken in. If you burn more calories than you take in day after day, you will lose weight. Simple as that.
