Not sure I would classify if as any plan really, I just had a think and a bit of research about the chemists involved and it seemed obvious. It's practically impossible, and it seems quite dangerous to cut out all carbohydrates. So I probably end up eating about 25 -35 g a day in with the other stuff.
The way I worked it out was that if my lady bod ran low on carbs over a long period it would switch over to fat as a fuel.
I might be completely off my rocker, but for the time I have been on this I have eaten whatever I wanted whenever I wanted, so long as it's not carbs. I have paid no attention to how many calories I have taken in, just eaten whenever I was hungry.
I'm no expert, it just looked logical when I researched the effects of sugar, carbs etc on insulin resistance and fat.
Being doing this for over a month now and still feel like I have bundles of energy and haven't died, yet.
