Even though ketogenic diets are not new, they are gaining more and more attention and use. Lots of benefits here to be found if you want to slim down and experience greater health.
Here are a couple of sites to explore where you can begin to learn about these diets, the foods that are good to eat, and some of the benefits you can experience from these dietary choices.
I find this a good background of information and have developed my own nutritional regime that really works for me based on this information as well as information shared on the previous post on the Blood Type Diet.
Have fun exploring and being super healthy!
