This is only an application, not granted (yet).

I think that "method" patents don't get enough scrutiny by the public. If you read claim one, what they are preventing is: anyone identifying someone with diabetes and then putting that person on a calorie restricted diet.

It's not clear to me why the government should grant a monopoly on this technique, even from a theoretical standpoint.

It granted, indeed. Albeit with a slightly narrower claim scope. See my analysis of the issued independent claim.
