I am sorry if this is not being posted in the correct place,etc. BUT I am somewhat new to MFP use an iPad and iPhone so have never used the forums before due to the fact that they dont show up on the apps and someone suggested that I do so I am using a computer elsewhere to ask for your help. To make a long story short I lost 65 pounds in 2010 by eating better, I didnt excercise because I hate it lol...and since then I have put 20 back on. I am having the worst time trying to get these 20 pounds off and dont know what I am doing wrong. Before I was doing weight watchers and since they changed their program I switched to MFP and have been doing calorie counting and excercise finally...lol. I started out at the 1200 that MFP set for me and the scale didnt move down, then I went up to 1500 and the scale is going up...I am frustrated and not sure what to do. How do I know how many calories I need, if I eat my excercise calories back or not etc?? I need your help please! Thanks in advance! I need this weight to get off of me I worked to hard to let it come back on!
