I first bought Mr. Varrier's book about 4 years ago. I would read, then re-read it for a couple of years. A year ago I decided to do low sugar/carb. Automatically, I walk around 20-25 pounds less every day, than I had since about 2000/2001. First it was 10 lbs. pretty quickly, I was happy. Next, it was another 10 to 12, and I don't have much more to lose. It first started out as learning then a hobby, which it still is. I think the replacing is the most fun about it. What really got me interested at first was the history of sugar. I had heard about low-carb before, but now it was more than only science. It made more sense after looking at sugar being introduced centuries ago. Then, sugar and grain becoming part of our culture made the situation clear. The science behind all carbs breaking down to blood sugar is interesting. What is really easy for me to understand is that your body can't burn fat until all the sugar is burned up first. Get sugar and carbs out, then your body has no choice, simple. Then, in the book explaining how conditioning relates to calories I finally saw it's really all about diet. I competed and coach wrestling which burns a lot of calories. No workout can keep up with a huge amount of carbs and sugar intake.
Here is the last thing that sealed it for me a year ago: the low-fat 90's fad. I'm no conspiracy theorist, but replacing all the fat with sugar??! They had to know. I'm a little embarrassed that I bought into low-fat.
So, all possibilities with low carb/sugar keep me very interested, along with the clear, quick, obvious results. The only thing I haven't tried yet are the sugar free sweets, that's next.
