Wow, I just stumbled upon this as I rarely frequent this forum. I just started a 'lifestyle change' for this exact same reason. I am 52, overweight, and 'newly' prediabetic. My plan is simple - eat right (paying attention to sugar/carb intake) and exercise at least 5 times a week. I've only been at it 2 weeks and at the very least, feel better. I am avoiding the counting/tracking since I had done that years ago on Weight Watchers, and don't want to spend that amount of time in the weeds. Don't take that the wrong way, I certainly care what and how much I eat on a daily basis, it's just I'm at the point where I know what's right and what's wrong. My numbers were/are high enough where medication was offered as an option. I declined them 6 months ago with the promise to myself that I would diet/exercise and bring them down on my own. I failed. Fast forward to today, my numbers are higher than before and I, based on advice from 2 doctors, am starting Metformin. My intent is to get the numbers down, drop the Metformin, and continue monitoring closely. If you can, don't fail like I did - get your numbers down on your own. To give you an idea of who/what I am, I'm 52 years old and at least 120 lbs overweight. Diabetes does not run in my direct family, but I have cousins who have it. My lab results from 6 months ago had my A1C at 6.1 (not horrible, but an early warning sign) and my latest home tests of blood glucose has been between 126 and 154. Time for me to get serious. That said, good luck to you. The lifestyle change has been tough at times, but, I have to deal.
