Does anyone know which website(s) are the most accurate for measuring how many calories you should take in? Food Focus, freedieting.com, mydailyplate, the LoseIt! iPhone app, etc.?
LoseIt tells me I should be limiting my calls to 977 to lose 2 lbs./week
freedieting.com tells me I should eat 1152 cals daily
and Food Focus tells me I should limit to 776 a day!
Those numbers are way too small for you to live on, so you would have to create a calorie deficit through exercise while maintaining the basic amount of calories you're body needs to function.
I agree that those numbers look really low. Be sure that you're not putting in an overly ambitious weight loss goal, like losing more than 1 - 2 pounds a week.
Generally speaking, it's hard to get adequate nutrition at a calorie level less than 1200 per day. I'd suggest you pick a number like 1400, try it out for a couple of weeks, and see what your results are. Then you can tweak if necessary.
I like Sparkpeople - if you put in a startweight/goalweight/timespan that gives you something as unhealthy as those numbers you posted, it just won't let you do it.
