MFP weightloss predictions unrealistic?

I find it pretty accurate, I did say I was going to weight 165 in a month and a month has gone by and I just happen to weigh 165 .

Honestly, I turned off the "notify my news feed that I've completed my diary for the day" about 4 months ago.

Wow, I never knew you could do this.

How do you do that?!?

Yes I sure do agree...It depends on how you log that day. If you log less than allotted calories or more than your allotted calories. It is very unrealistic :noway:

Pretty unrealistic, but can be quite amusing if your intake varies day to day because you pay more attention to your weekly average.

One day last week I was using the phone app and managed to hit the complete button by mistake for the following day before even logging any food for that day. MFP still told me what I would weigh in 5 weeks' time - so now I know that if I ate nothing at all for 5 weeks I would weigh about 20lbs less...

I ate exactly the same for 2 days with no exercise but the little prediction box told me 2 different weights, after that I stopped taking notice...

if you log less calories or more calories than your goal, the number will be way off, but the number is not "unrealistic", it is based on MATH. If you "eat like this EVERY DAY, in 5 weeks you will weigh..."

this means if you log a low day and click it, it runs the numbers based on that amount of calories every day for 5 weeks, or if you eat OVER your calories, it can show you gain weight in 5 weeks, because its based on eating that SAME EXACT AMOUNT every day.

It is only a "fun fact" and a cute little thing that some people like to click for shits and giggles, it is in no way meant to be accurate or used as a tool to judge your progress.

I get a big kick of seeing what MFP predictions are every day. It motivates me. But at the same time… I realize they are only "accurate" if EVERY day was exactly like that day (every day my calorie intake and burn was exactly the same and that everyday I weighed the exact same amount). And that accuracy also presumes that my food logs and and calorie burns are 100% accurate. So, while I love seeing their number, but it's not like I hold any degree of confidence by it or really pay any real attention to it. It's not like I'm marking my calendar and every time I get to the "5 week" mark I compare my results to whatever MFP told me it would be.

MFP is working fine for me, in fact I reached my weightloss goal today (yeah!) though I may reset it five pounds lighter. We'll see. I just wanted to know if others had a similar feeling...

Haha - I must learn how to do this!! But, YAY!!! and Woohoo!!! Congratulations on reaching your goal!!!

I found it to be pretty accurate.

Right. So it'd theoretically be correct assuming these things:

1- You ate that amount every day for 5 weeks.
2- Your deficit logged is accurate (so your intake tracking is accurate and your burn estimates are accurate)
3- You lose only fat, no significant water gain/loss (or other)

Personally i love the possibility it shows me 5 weeks away,,,, keeps me looking forward. On days when i have not really achieved much defitict it shows my weight loss will be slower, so quite motivating.....

Congrats on your weight loss, awesome job.
