35 days is about right for the awful "plateau" effect - on any weight loss plan. Counter-intuitive though it may be, a day or two at 1600 - 1700 calories might set you right. In fact one day a week of 1600 calories won't slow you down and may increase weight loss.
When I had over a hundred pounds to lose, I lost 21 pounds the first month. Subsequent to that the next few months were 13-14 pounds per month, then 7-8 pounds per month. Anytime my scale stalled for more than 10 days, I ate a nice healthy 1600 day, even if it wasn't one of my weekend 1600 calorie days.
