Welcome to the family, ES15!!!
As you can tell reading Umpa's response to your post, in the beginning keep it as simple as possible.
As time goes along, you can add more things, change things up, etc..
But for now just focus on staying below 20 net carbs a day and NEVER allow yourself to get hungry.
When we get hungry, our body tries to stop the
weight loss process as a survival mechanism.
Don't worry too much about exercise.
It's good for overall health and to keep the metabolism going, so it's recommended.
But it really does little to lose pounds.
It takes a LOT of exercise to lose just 1 pound.
One other important thing... Drink LOTS of plain water EVERY day!
It flushes out "burned" fat and other toxins.
It also helps keep the skin elastic so excess flab from losing weight is less of a problem.
