I had surgery (bypass) on Mar 5. I have steadily lost .8lb each day. I have written down every calorie and every gram of protein. My question is On Thurs I ate 400 calories and 75g of protein walked for 25min. On Fri I copied everything to a tee from the day before except 1 sugar free popcisle at night and my exercise was doubled but I gained 3.8lbs. Anyone explain the abrupt weight gain? Sat I went down 1.5lb (same) food intake but less exercise only 45min. I know alot of ppl stall at 3wks but this wasnt a stall it was a gain....

that wouldn't be a true weight gain. Could be constipation, water retention, or hormones. It'll probably be gone in a day or two.

yes i lost 1.5 lbs the next day. "1 step forward, 2 steps back"
