I just found MFP and I've been reading the community forums. Very helpful! But I need help. I'm a 45 yo female, 190 lbs. I have been tracking VERY CAREFULLY (every single thing weighed and measured) for 4 weeks now. I am down 9 lbs, which I know is a decent number for 4 weeks. The problem is, I lost all of that in the first two weeks of tracking and now, in the last two weeks I can't seem to lose ANYTHING. Every day the scale is within .2 of a pound from the day before (typically going UP) or at the exact same number as the day before. I'm at 1450 cals per day. I have a sedentary computer job all day but I do walk 3-4 miles a few times a week. What am I doing wrong? Could 1450 be my maintenance calories? It seems so low for maintenance. MFP tells me to eat 1380 per day for a loss of 1.5 lbs per week. But in the past I've always eaten at 1600-1800 to lose weight. Is it just because I'm older now? Or am I eating too low?
