Oh Honey, I just have to ask...How "little" was your "slip-up" on Saturday?
If you had a 3000 to 4000 calorie little slip up I can see eating a very low amount the next day, simply because who could be hungry after a big blow out like that? As far as the "starvation mode" comment (after one day of eating a low calorie amount)...No way. I don't know why people freak out if a person has one very low calorie day, after a very high calorie day. It's not like your body "resets" after a specific 24 hour period. Your body does not go by the clock. I have many, MANY times fixed damage by eating less for a few days after an over indulgence. I call it maintaince.
My Mother and Father-in-law who are in their upper 80's and have NEVER had a weight problem do it all the time. If they eat to much one day, (like Christmas or Thanksgiving) they cut way back the next, (because they are NOT hungry...and normal weight people do not eat when they are not hungry...) Over weight people eat when they are not hungry!!
Now, to the 1/2 pound gain. Well, how much did you poop? How salty was the "little slip up"? Was it mostly carbs, (that make you retain water) or protein?
A few weeks ago I had a little slip up. I ate fried chicken and ice cream...I estimated I went over my daily calories by about 2000 calories that day. IT took me an entire WEEK....yes, 7 days of 1200 to 1300 calories to get back to 140. I gained 6 pounds overnight, and it took 7 days to lose it. Whether it was bloat, water, sludge or fat, it took 7 days to lose it. Thankfully I learned my lesson for now.
