Welcome! Wishing you all the best with your new job. Schedules can definitely help, just don't let yourself get too hungry. They can also be exhausting. More doctors are starting to get on the low carb wagon, it's actually cool that yours is. I wouldn't focus too much on the fact that your doctor recommended a 15 carb/day diet, that's pretty close to impossible. But definitely look into it, read Dr.Atkins and Dr. Bernstein, and there are so many others. There are tons of videos on YouTube that can motivate a low carb diet. Anything by Drs Phinney and Volek, and more.
Give it a go
