I have used Fitbit. I’ve got one and I’ll wear it every so often. But, for me, it’s more of a "Good To Know" type thing than it is an actual exercise meter. I do programs such as "Insanity" and "Les Mills Combat", so the steps I take during the day don’t really add anything after I do those routines.
I was right where you were. I am also a Military vet and I had 2 quadrupal layer neck fusion surgeries. I ended up with a total of 1 bracket, 2 rods, 12 clamps and 22 screws in my neck. After my second surgery and the miltary deeming me "medically disquailfied for continued miltary service" I was forced to retire at just under 18 years. I let myself go after that. In July 2012, I walked past the mirror and looked at myself. I was shocked. I got on the scale and weighed more than I ever had in my entire life. I decided right then and there I was going to make a change. I was going to get in much better shape, I was going to lose all the extra weight (plus some) and show those military quacks they didn’t know what I was capable of. Long story short, in the last 8 months, I was able to lose all the extra weight and drop 5 lbs below my goal weight. I have completed multiple fitness programs and I have even become a Beachbody Coach to try and help others get their fitness journey. One thing I have noticed, it’s not just a diet and exercise change, it’s a lifestyle change. And, it’s a good one.
So, congrats to you on deciding to better yourself by becoming fit. Good luck on your journey and, if the Fitbit helps keep you on track, by all means, use it everyday.. Also, in case you want to work on your nutritional habits, myfitnesspal.com is another free website out there that has been a HUGE help to may of us. I have nothing to do with the site, besides being a member. I just know it has been a great help to a lot of us.
