It not how many calories are in something, but what your body does with the calories. When you keep your carbs low, your insulin levels stay low, so instead of storing calories as body fat, your body is free to use them to feed your starving cells. High levels of insulin mean that your body is storing fat, and starving your body cells which need the energy.
Think of it like having a job where all the money goes into the bank and you are only allowed to get out 5% because of a nasty bank guard named insulin. So despite the fact that you have a good job, you are homeless and starving on the street. So you get a second job, and the same thing happens. So you get a third job, and the process repeats. The 4th job helps a bit, but not much. It does not matter how hard you work (how much you eat) you are homeless and starving.
Cut the carbs, get ride of the fat guard and you can get the fat out of the fat bank.
I use to have to eat every few hours or I would have the shakes. I have not experienced that in years. If I am busy doing something, 5 or 6 hours can go buy without my even realizing it. A low carb diet isn't just about losing weight, it's about improving your overall health and well being.
