My Big Fat Gut

Well, it's come to this. Trying to find motivation to reduce my waist size, I've been reduced to blogging. Not sure if this is the cure, but I'm going to give it a try.
A little about me...I'm a male approaching the big 50, about 5'8" and checking in at roughly 195lbs. According to my scale, it says I have about 28% body fat. Now I know this isn't what many would consider obese, but it is overweight.
 My occupation is that of a facilities maintenance mechanic. I make a living building, repairing, and modifying equipment and building related items. That folks is what bothers me. I've noticed a drastic decline in motivation and stamina over the last few years. But most importantly, I just feel like a slug. Having a job that requires physical exertion and being able to work off of a ladder as well as work on the floor, having a big fat gut makes it much more difficult. I definitely don't need any added obstacles.
Anyway, I'm going to try and lose my big fat gut and the purpose of this blog is to keep me accountable. If anyone out there has any suggestions or pointers for me, feel free to comment.
