Hi Joe and welcome!!!
I went to the dr back in April and he put me on 1700 calories, exercise at least 150 min a week, Vitamin D and magnesium supplements. About mid May I started walking 2-3 miles per day and held my calories to about 1550 -1650 calories... not on purpose really was just not as hungry... since starting this I have lost 55 pounds with this lifestyle plan and 72 overall down from my highest weight of 390... I eat what I like and I do not deprive myself... mind you if I feel weak at a particular time then I just wont go around the food... ie work or whatever... when I feel strong I allow myself a small portion of whatever it is that would normally make me weak just so I do not feel deprived... I mean I have to learn to live with this stuff right?... the main thing I do is that I count every bite as best I can... and if necessary I compensate by eating a lighter dinner or walking more if I have had more than I should have... There have only been 2-3 times since April that I have come out on the wrong end of the calories... I also never beat myself up over too much of anything... and will start right back the next day eating on plan... (this is the first time in my life that I have been able to do this with any amount of success)...
that is my plan in a nutshell... I know you have to explore and do what works for you... something I eat on my plan might be a trigger food for you... I will say this... my plan would probably bore some people... but it is fairly balanced...
I wish you all the best and hope you will hang out on the boards especially when you need motivation or just someone to listen to you...
