Welcome, hewmon. There's a whole bunch of us 50+ lifters here that, like you, have spent a lot of time doing other things until starting this path in our late 40's or early 50's.
At 52, don't feel that you need to adhere to the GOMAD concept, even if you're using heavy cream. Robert Santana talks about that here. If you were 145lbs, that might be a different story. And eventually you'll find that low carb won't quite cut it. That has happened to most of us who came into this eating that way. You'll have to start adding in carbs as the weights get heavy. There's really just no way around it. Check out the Nutrition & Recovery forum for plenty of threads on that; plus, Robert is the moderator, so he can answer any questions you might have.
Stick to the program. It works!
