<human>: So I had been lurking /r/loseit for a little while when I decided about a month ago I was going to finally start my own regimen, and joined myfitnesspal and a local gym as well.  I've been counting calories and doing occasional small workouts, and I've always managed to end my days entry with less than my goal, although the last week or so, I've had days where I started to feel hungry at the end of the day, and ended up snacking and coming quite close to going over.  Yesterday of course being Thanksgiving, I figured what the heck, I would just go crazy and go over anyway (you have to some cheat days, and what better excuse than a holiday about eating?).  I went over by about 500 calories.  I completed my entry, dreading the "In five weeks you would weigh..." number, since I assumed it would show a gain in weight.  Turns out, even when I went over by such a margin, mfp still projected me to be losing weight!  It was only down 4lbs in 5 weeks, so basically no change, but I was so surprised...  I suppose it shouldn't have been a surprise, and maybe this just makes me look stupid.  But knowing that there's that much forgiveness built in right now, it makes it easier.  Of course, I still plan to try to stay under as much as I can, but now I won't agonize over those end-of-the-day hunger pangs.

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: Myfitnesspal has a buffer in terms of calories, helps with guilt issues if you come close to going over.
