EDIT November 2014:
I no longer endorse Ketosis for the long term, over the long term ketosis threw my body into complete disarray, my hormones and cortisol is really out of whack and I'm working really hard these days to get my natural energy and sleep balance back. Please do your research and if something doesn't feel right then make sure you question it.
Hey guys, I have dipped in and out of ketosis for close to 5 years, I don't always stay in ketosis 100% of the time, we all know that I love to have indulgences every now and then and I like my treats, however the majority of the time I spend in ketosis is because it helps the myriad of health issues I have struggled with all my life and I feel my very best in ketosis.
I've posted this video to help those of you that also may struggle with these issues. Please don't think you have to achieve nutritional ketosis to get the same benefits as I have, we are all very unique and you need to treat your body with the respect it deserves. Ketosis is a stress on the body much like exercise and calorie restriction (not always a bad thing) but if you are living a stressful life and already exercising and dieting then doing a ketogenic version of a primal or paleo diet may not be what is right for YOU! I cannot figure that out for you so please use a diary like I suggest to find your right version of Primal/Paleo.
If you have only been doing low carb for less than 6 weeks then you might be disappointed in the results if you buy one of these machines as you may not be keto-adapted yet. It can take 1-6 weeks to achieve ketosis. See more information below.
When it comes to eating real food I believe that most people will experience some significant health and weight loss results without having to go on a ketogenic diet.
