Sean, RE: trainer. I didn't have one but when I see them at the gym with people starting their journey's I envy them. I can say for sure that diet will ultimately determine how things go for someone. And not "Diet" with a capital D, but diet as in just paying attention to what you eat. I didn't. I didn't give it a thought. I didn't put it together back then - maybe didn't want to. I liked drinking bourbon and eating what I wanted. Loved it even.
But enough is enough after a while, like you say. I didn't want to end up in a hospital with something I could've avoided.
I did try weight watchers years ago and lost like 15 pounds -- hit a plateau, got frustrated and put it right back on.
What ended up working for me, regarding eating, was learning to account for intake vs. output. It really is as simple as understanding the energy/caloric value of what I was packing away in relation to what and when I was exerting the energy. I found a logging site (free) that I thought was handy and you can join up with friends for support and make groups, etc. It made it fun. There are a number of them online, but I stuck with this one because it played nice with my heart rate monitor, Runkeeper app and some other fitness apps I use. Super slick and really made losing the initial weight easier than I would've imagined. But more importantly, it made me more aware of how to eat. I know that sounds stupid but I just never gave a thought to what a 'portion' or a 'serving' was. It turns out that stuff's actually important. heh.
It's called
http://www.myfitnesspal.com/ -- It's self-explanatory when you see it. And like I said, there's a bunch of apps like this and I'm sure they all work well. I just liked this one because it's free and it works and thought their food database and search function was top of the heap. Been using it for over a year and it just works. Exercise -- is a whole other game. I've got some fun stories with that over the past year as well. Maybe later. Entering my first sprint triathlon this fall, and I have my first Tough Mudder in MA in June. Can't wait.
Edit: The companion app for myfitness pal is another nice free one called Endomondo at endomondo.com, if you like tracking your workout progress mileage/stats/pace/cals/HR. Pretty complete if you like looking at your numbers.
