So how accurate is MFP when it tells you " you will weigh XXXX much on this date if...etc" ???

Ive been really gettin into this MFP thing (even though I told myself not to get too crazy but hey I dont have a lot going on right now anyways LOL) and entering my calories and all that. Im pretty diligent about measuring stuff out correctly. Im only trying to lose this extra 10-15 lbs I gained in the last few years and today MFP told me I "should weigh 117 in 5 weeks" ....Im a bit skeptical though since I feel like ive been trying to lose this stupid extra weight for a while and its only been a couple weeks and my weight hasnt budged much yet (SW 120-123).....

so how accurate is this?? I know it depends on a lot but i mean if every day WERE To be like today, is it really that accurate? haha

And sorry if this is a pretty stupid question ..... xD

It's not accurate. It's an estimate based on algorithms that estimate your calories out for the day and your inputted estimate of your calories in per day. Both vary and therefore results vary.

Its hard to get everyday at the same deficit, even when I was on a meal plan (1200 cal per day) and was weighing out all food and doing the same amount of exercise I got different deficits. I never got to the predicted weight in that 5 weeks. I kept a spreadsheet of my ins and out and then worked backwards to get a estimation that worked for me. Over 13 weeks I got pretty close to my re calculated loss projection, some weeks were still up and down due to hormones, salt etc.

I did however find I had medical condition during this period. MFP works on 3500 cals for each pound. I had to get a 9000 cal deficit to lose a kg (MFP would calculate 7,700 cal deficit to lose a kg).

Its a great motivator esp when you see a new low in the prediction. I would love to see it as a weekly thing so it had a better look at your average eating and movement (which is what I got my personal calculation to do).
