agree with qfk.
I am near 6'2" and was up to 387lbs about 3 years ago. I'm 47 btw.
Discipline in good nutrition + workout every time = results.
That goes for us all of course.
I've been under the knife too, and even one surgery can cause problems with your entire body and your mind.
Personally, I suggest adopting a pure "never give up" attitude about your body if you haven't already, and it IS yours so it's up to you how it looks.
Avoid the "latest crazes" like gluten free (still?), Adkin's, etc. Read up on nutrition here because the articles are golden.
Finally, set your goal(s) for body composition, plan how to achieve it and execute. It's easy to do the first two but the last is where the rubber meets the road.
Ask questions in this forum because I'm pretty sure the guys here can offer better advice for those of us who are "seasoned."
I recommend looking at articles here by Christian Thibideau. There's a forum for him as well....he gives advice from a longevity perspective too.
I've just started his program titled, "The Best Damn Workout Plan for Natural Lifters" and it makes a ton of sense. Six days a week at about 35 mins per day, covers all the muscles.
Best of luck and keep us posted.
