1st I will give U a bit of my history. I started low-carbing 14 months ago. I reached my goal weight last sept. but cause I knew I would be quitting smoking I stayed between 132-134 for at least 3 months. I quit smoking 9 weeks ago using the patch and I weighed in this morning at 137. Several things can contribute to my weight gain.....1st metabolism, 2nd water, 3rd the fact I started doing resistance training 6 weeks ago. I may well gain a few more pounds being off the patch now however Im certain it wont be much AND my clothes fit the same as they did 2 months ago. NOW having said all that.....I looked at your profile. U are 5'6"...same height as me. How old are U? Im 37. I wonder if U were under weight for your height? Im thinking because U are a non-smoker your body has adjusted to a more healthy weight for U? Also I can see for certain U are starving yourself. 1000 calories a day is not nearly enough. U need to eat at least 10X your weight in calories a day and I think that is even way to low. I didnt change my eating habits much since quitting smoking. I hear the worst thing U can do is to cut back too much cause that isnt good for your metabolism. I use a site www.fitday.com and most often I am eating 1900-2700 calories a day. Also U may NOT be getting enough carbs. Too few carbs can cause a weight stall. Are U drinking lots of water? Takeing supplements? I hope my suggestions help and please feel free to ask if U need more help.
