I completely understand where you're coming from. I came back from 5 days at the beach during which I ate like there was no tomorrow and was five pounds heavier as of last Monday when I weighed in
But now it is 10 days later and four of those five pounds are gone. So, first thing is to keep in mind that whatever the scale says over the next couple days is likely not all fat gain, but water and other yukkies that come with eating food you don't normally eat. Get back on a clean eating schedule and do your exercise; drink a lot, like you said, and tell yourself that you goofed, but move on. Don't let it be an excuse to go off the track.
If you look at the numbers, you may see that you didn't do all that much damage to begin with. I tried to access your food log with the link but it came up blank
. Anyway, how many calories did you burn yesterday? How many did you eat? And, how much over were you? You could try making up that excess by having a deficit over the rest of the days of the week, rather than trying to make it up all at once today.
Another thing...related to linusfuller's post: yes, everyone is different and all bodies react differently, but 1000 calories a day seems low. It does work for some folks; are you very petite or postmenopausal? Just keep in mind that the longer you maintain calories that low, the longer you are "training" your body to adapt to that level of calories, and who wants 1000 calories a day for the rest of their life? I really believe that calorie cycling (zig zag) is helpful because it keeps your metabolism guessing. If having 1000 a day works for you, great; but also be aware that it could backfire over time by slowing your metabolism down. That could be really important when you have slip up days...if your body is "used to" higher calorie fluctuations to begin with, it won't hoard the calories it gets on a bingey day.
Last but not least, you did great by coming on here and posting. This might be a good time to journal some thoughts about what happened, make a plan for next time, and forgive yourself and move on. Getting over the mental hurdle is sometimes harder than getting off the few ounces you might have ultimately gained. Good luck; eat well, exercise, and you will see over time that you really didn't do all that much damage in a night
