31 weeks

I have been doing no sugar, no flour for 31 weeks now and have lost ten pounds. I also do intermittent fasting and have a five hour eating window. For the last 16 weeks I have been gaining and losing the same three pounds. I have done different trials for two weeks to try to see what’s going on including cutting out coffee, one meal a day, a meal and a snack, one joy meal a week, extending my eating window, two meals a day, etc. What am I doing wrong ? Please help.
