In 6 weeks of Low carb using Atkins as a guide, I have come across so many inconsistencies!! The one I don't get is we are admonished not to cut down on fat if living on less tha 20g carbs a day but then also told to limit avo, olives, spinach????? (that's very odd) etc. So really you do have to count calories is the bottom line in addition to cutting carbs? An aside .... As we are a global village I really wish we could standardise measures, so confusing!! What is wrong with the metric system?????
