She is referring to a diet called CKD. Basically eat low carb all week then carb up. Carb ups are usually short phases ranging from one meal to two days, where you increase calories from carbohydrate sources while decreasing fat calories at the same time. Or you could throw that "rule" out the window and do what most people do, eat what you want for one meal, but when you're satisfied resume low carb. As for taking ALA to induce ketosis, it will work, and personally I think it will be in the order of 200-300 mg spread over three of your first meals. As for using it during carb-ups, that really depends on how much you pig out, and how long you have been doing low carb. The longer you've been on, the less effective your cells are to insulin and you will have to rely on greater dosages to get the same effect as when you first started CKD.

Hope this helps.
