There's also an exercise component, and a gym membership is included in the plan membership fee. I haven't started that part of it yet; before I do anything, I need to meet with a trainer to discuss what I can and can't do. Back in 2000 I tore the cartilege in my right knee and underwent arthroscopic surgery, and I have a history of weak ankles, so I want to get some guidance about what kinds of activity is safe for me. That's on the docket for next week.
So far, the biggest adjustment has been cooking for myself. I never cook! It's not that I can't cook; I just don't like to. But now I have to, because eating frozen meals or in restaurants is strongly discouraged. That's going to take some getting used to, but if the first two days were any indication, I think I can handle it.
The other thing that will take some getting used to is eating breakfast. I don't normally bother, but now I have to. That means I have to get up earlier. I have been getting up somewhere between 5:45 and 6 AM, but now I'm setting the alarms for 5:30 AM so I can fit in a meal. Yuck. I need to start going to bed earlier.
So far, the plan seems to be working. As of last Thursday, I'm down 9.5 pounds. That may be water weight, of course, but nevertheless it's an encouraging start.
