I have to admit, I actually do eat fruit every day. The problem with fruits, according to the Atkins diet, is the amount of sugar in them. This sugar can cause spikes in your blood-sugar level, which causes you to produce insulin and gain weight. Also, when I said "most fruits" I was taking into consideration fruits like tomatos and cucumbers, which are low sugar fruits. Bananas are pretty much nothing but sugar.
The Western diet is high in grains and starches. It is hard to find a single restaurant that doesn't serve French Fries with more than half of its meals. I have nothing against that diet, personally, except that it allowed me to gain a lot of weight without realizing it.
Atkins allows any kind of seafood, beef, chicken, pork, eggs, most cheeses, most vegetables, many seeds and nuts, and a few fruits.
I was quite skeptical of this diet before I tried it, but I can actually feel a big difference in my energy level. I can eat an entire rack of ribs or a huge steak or a hundred clams and not gain any weight.
I have been able to stay up later at night, and get up in the morning more easily. And my allergies are minimal. (My allergies were not food allergies, except milk. I am allergic to dust, animal dander, pollen, and smoke. These things have minimal effect on me now.)
