I agree with Mary,
1200 is probably too low for you at this time. Plus trying to do everything all at once is a recipe for failure.
Here's a suggestion: For a week or 2 eat as you would normally. Enter everything... I mean everything, good, bad, and indifferent into FitDay. If you can I would even suggest using the Moods and Journal tabs to log what was going on in your life at the time. Then use all of the tools available to look at the calorie balances, the nutrients, etc to analyze what and why you are over eating.
Then select 1 thing to change, just 1. Is it too much ice cream? or too much time at the pub? or is it too much snacking in front of the telly? Start with 1 thing for a week then add another after a while.
Me? I found that I was a lot more lonely than I ever suspected. I am married, I have lots of friends, but I am also a pretty high powered research professional with a need for a lot of time to reflect (my DH is quite similar). But I found out that all of these things were causing me to isolate myself too much and I was overeating in reaction to being alone too much. Now that is something I can change, so I did, with nice results.
So my dear Ms. cornycow. Take hold of your life. I totally admire your desision to do so - I was well along in years before I did
And we are here for you... good, bad, and indifferent.
