    I haven't paid any attention to that number, as I keep my own projections. But, I wonder if it's based on the weekly average net calories, so a rolling average to the particular day you're logging, rather than a single day. To me that's a reasonable way to approximate it, but maybe there's just flat out a bug in their algorithm.
    Yeah that's what I was wondering. I love math so it looks like I have some reading and research to do. ☺️

    I wish it were accurate I would have been at my goal 6 months ago! Lol

    No. It's just based on the day. It is based on your net for the day. So unless you aren't entering your exercises, something does seem off. Can you open your diary?

    Oh. Also, you CANNOT go back and look at a previous day and see results based on that days weight. So if you go back 5 weeks, MFP will estimate what you would weigh based on TODAY's weight and your deficit for that day. So If I go back to last September when I started, it tells me I would weigh 238 in 5 weeks. Last September I was 320 lbs or so.

    I started noting the 5 week number in the notes after I closed a day.

    The "you would weigh X in five weeks" is simply an algorithm based on what you ate THAT DAY. People have mixed reactions to it - some find it motivating, some find it completely irrelevant to their progress and in fact, get frustrated with it because it is not accurate - weight loss is not linear and cant be predicted that accurately.

    Personally, I ignore it. It is not possible to eat exactly the same thing in the same amounts every day, so its really meaningless.
    Im one of those that get motivated when i see .. " you'll weigh x in 5 weeks"

    I can open my diary if you promise not to judge
