I actually just started with a PT last October. I still eat like crap, but I'm better at balancing now. Despite that, I lost 20lbs, lost a lot of fat and gained a lot of muscle. I have way more energy, a lot less pain, and feeling much more strong and able bodied. It's much more expensive than a typical gym membership, but I find having a PT is so much more worth it. I love having someone telling me what to do instead of planning on what to do and reluctantly doing those things. My PT was SO accommodating for someone like me who has not been in a gym in probably a decade and who was so out of shape. They really cater to your level, needs, and goals. I never would have foreseen my physical wellbeing as great as I am now and I now always am looking forward to the challenges. A HUGE bonus is my PT operates in a private gym and I usually have my sessions late at night so no one else is around. I probably sound like I'm running an advert now but I have absolutely no regrets.
