I think it's pretty sustainable. You should approach it as a lifestyle change, though, not a diet. That means don't make any tradeoffs in the process you're not willing to live with for the rest of your life. For me, that means find the occasional space for pie, and chocolate, and pizza . . . But once you've got the initial engineering figured out, it's just a case of knowing what things cost in unusual circumstances. A little mental effort for a healthy body weight is a tradeoff I'll gladly make for the rest of my life.
