Hi Joey,
You have found a great forum for information and support. As you see, it supports all kinds of low carb plans. But since you said you read Atkins and know that one, you can start with this summary at the top of the Atkins sub-forum. http://forum.lowcarber.org/showthread.php?t=236482
You can stay on this "induction" plan as long as you like if you wish, or move to phase two. The Ketogenic Diet, a stricter version of Atkins if you will, is all the rage now. A good beginners guide here, another website filled with information, videos, etc. https://www.dietdoctor.com/low-carb/keto
All the best,
