Just diagnosed with Type 2 Diabetes

I'm 48, and I was just diagnosed with Type 2 Diabetes. I'm 6' and weigh about 212 pounds. I put on 20 pounds in the last year. I've been prediabetic for around 14 or 15 years, and my A1C levels finally eclipsed the threshold and came back at 6.6. My doctor left it up to me as to whether or not I'd be prescribed medication (Ozempic), or if I wanted to wait 6 months and see if I can get my A1C levels down on my own. I chose to try on my own.

With that being said, I'm reading up as much as I can on a proper diet. My doctor mentioned Keto, and it seems that any of the low carb diets would benefit me. Are any of you going through this as well, and if so, how do you plan your meals out? What do your meals typically look like? I'll search through some of the threads here for more info, but please chime in.

As for working out, I injured my calf about 2 months ago and couldn't run. I injured it again about a month ago, but I've finally been able to run (slowly) a couple times without reinjuring it. That used to be my only workout, and I'd run 4 to 5 times a week. Now I'm cutting that down to 2-3 times a week and doing weight training 2-3 times a week. I just started this but since I can work out during lunchtime at work, it's easy to stick with. I'd like to get the A1C under control without meds, so I'm hopeful.

TLDR Version - 48 years old, A1C levels of 6.6. Offered Ozempic but would like to lower A1C with diet and exercise. What does your typical daily meal plan look like? Thanks!
