when your calories jump up for a day or two..

why is it that whenever I increase my caloric intake one day, I inevitable eat more calories the next? Iam 5'10, 170lbs and I am trying to maintain 1600 calories a day. I love working out and try to burn at least 400 cals a day at least 5 times a week. I find that I can maintain between 1600-1700 cals/day comfortably for about 4 days before my calories jump into the 2,000's for a day or two. After this day or 2 I get back on track. Why does this increase happen and what can I do to keep it down??

actually tahts the same with me - i do really well and then i feel i'm craving more after the same time period!  some insight will be good for me to...

getfit20 why not try to just eat extra high protien/fiber and keep the calories the same on thoes days where your calories would jump? 

consider it as zig-zaggin..That's what I would do..

thats what happens to me to,normally i would eat under 1000 calories and some days i would eat next to 1300 calories but would feel gulity about eating over 1000 calories so the next day i would make myself go no more than 800

no matter what level you are at... girlywhirly3000, you shouldn't be eating less than 1000 calories.. infact you shouldn't be eating less than 1200 calories... you are starving your body... thats why the tendency to overeat (hardly if you ask me.. its more like eating straight) occasionaly... i would suggest to up your calories to 1200-1500 and you will still lose weight provided you eat healthy... and exercise just a little bit.... and you wont crave so much either.
