Quick measurements... 25yr 6'0 205lb 16% bf

Hey guys...I have been in the gym for a little over a year now. When I first started going I was around 220lb, slowly but surely I kept at it and I started losing weight. At my best, I dropped down to a slim 189lb haha I hadn't been under 200lbs in a long time. Anyways naturally I think I hit my plateau and my weight started to go back up. Of course I added a lot of muscle so I really didn't pay too much attention to numbers (weight). I took a couple of months off and really noticed a change in my body, I had dropped down to a 34 waist that were pretty loose, but had now kinda gotten snug. So two weeks ago I got back into the gym and have really set some goals for myself. For a week now, I have not had one meal from a fast food place or anything like that. My diet has been the real problem the whole time. Even when I started going to the gym over a year ago, I had a horrible diet. Now I am really focused and want to achieve some great results....

Any suggestions would be greatly appreciated. Ask away if you need to know any specifics...

I have changed my workout to a split routine, instead of full upper body workout and a full lower body workout.

You changed from a split to a split?

Welcome. Read the stickies...there's lots of good info there.

haha no. let me better clarify

I went from three days of full upper body stuff

to

you know, back/chest monday, shoulders/arms tuesday and so on...

That's a step backwards if you went from an upper/lower split to what you're doing now.

And if that's what Monday & Tuesday are, then you're wasting your time.

can you please explain?

If you were doing an upper/lower split, then I assume you were training both upper & lower twice every week. Now you're backing off to doing one body part per day per week...meaning there's less stimulus for growth if everything is trained only once per week.
