I found this cool weight loss coach app called noom.
It has some cool things like it will use your phone's accelerometer as a pedometer (which, since I almost never have my phone in my pocket, it's that useful.) Let's you scan UPCs with the phones camera (had about a 50% hit rate. Though, really, chocolate frosted mini-wheats should not be "health cereal.") And has some interesting articles, fitness tracking and personal goals for each day. You can also set meal logging reminders.
Now, that being said, what I really found out is I just can't any more. I can't log my food. It makes me grumpy and angry. I need to find a way to change what I'm eating with out thinking so hard about it and with out being told that I can't eat any more today. I really makes me just want to never eat again, which isn't healthy and not something I can do. So sadly I'm going back to using fitocracy, which only logs exercise, because then I feel good entering in new exercise and even find myself doing something just so I CAN enter it.
I think I really do, especially this late in life with the genetics I'm fighting, just focus on being healthy, not being thin. Regular exercise, being active and mobile and moving and eating good things.
