Are you able to get a referral to a dietitian, who sees you at least once or twice a month? That would be one of the best ways, it helped my husband and I the most. Bet she puts you on a 1,500 cal per day plan, that 1,200 is gonna get too low for you, because you have to be realistic, and think more "lifetime", you won't last on 1,200, especially if you begin to exercise every day, you don't need to run or do laps right away. Also, our dietitian told us anything we drink counts, no need to force down those water numbers, unless you love plain water. That water business stops some people from continuing right there, another excuse. Do a little exercise each day, if that's all the time you have, it's hard when you have a family to look after. And with a desk job, it makes it harder. Get in what you can, and if you can't, move ON, next day, keep at it.
