I'm not tracking macros anymore either. The first couple weeks I did, and now I have a feel for what keeps me around or under 50gm of carbs. It seems to be working, slower than I prefer, but I'm impatient.
I agree with Susan on the artificial stuff your gulping down. If it doesn't bother you then go for it. I am personally a little freaked out from what I've learned about our 'frankenfoods' so I am sticking to real food low carb eating.
For example: The Slimfasts have long list of artificially created ingredients, but it's the canola oil that stops me in my tracks. What I've learned about that so called healthy oil is pretty disturbing. I'm done with it.
The Atkins uses sunflower oil which is very similar in the processing but cranks up the rancid omega 6 fats I'm trying to avoid. Plenty of folks have great weight loss success with these types of products and 'foods', but I am as interested in long term health as weight loss in addition to trying to find my fuel locally, organic, and or sustainably produced.
I know a Canadian rape farmer pretty well. I'm just stunned by the sheer tonnage of insecticides he dumps on that crop. That's where your canola oil comes from.
