Although it's variable, the figure I've heard as being healthy and reasonable seems to be 1-2 lbs/week. I've lost more some weeks, and always lost at least a pound, but I'm not young anymore and I think that may make a difference. I wish I could count on more, and I do have goals in mind, but it's important to never lose sight of the fact that 1 lb is better than zero, and there may be weeks where no weight is lost, or weeks where there are inches lost and no weight, or weeks where you lose more. IMHO, to be sustainable, it has to be more about eating well and being active for a healthy lifestyle for forever. And hope the pounds drop off over the long term.
Gosh, I wish that I could just get this weight off in a few weeks, but that isn't realistic. I normally eat 1300-1600 cals/day never less than 1200 and never more than 1800 with the low and high counts maybe once a week each. I normally exercise 1/2 hour to an hour 6-7 days a week.
I started my plan on Feb. 20 and have lost 23 lbs as of last Sunday, which is probably pretty good. I lost 10 lbs the first week, but that often happens to people when they first start.
Hope that helps. It's good to have goals, but make sure you don't beat yourself up, and especially don't give up if you are not exactly in the time frame you set for yourself. It isn't all or nothing, it's a steady downward trend that counts in the end!
GOTTA GET OUTTA THE 180'S THIS TIME!
