I have been following the Atkins diet successfully for about 4 weeks now, however I am having problems trying to source some basic ingredients in Australia which pop up in your recipes.The most important of these is Soy Protein Isolate. All I keep getting offered are protein drinks which are way too expensive to use for cooking by the cupful, (especially since our dollar is so low compared to yours). Are protein drinks the only form that this ingredient can be purchased in? Is there something I can substitute for Soy protein isolate when cooking - (eg baking) that will give similar results? As we do not have manufactured low carb foods available, I basically have to make my own. Please help.
