You all should really try Livestrong. com. It is a web site sponsed by Lance Armstrong, the cyclist. It has really helped me. It also moniters your diet if you are a diabetic.
I was at a funeral this week so I didn't eat my normal meals. But I preplanned what I would eat and I stayed under 1,600 calories each day. I also haven't been exercising because of the heat, it was 116 at 6 pm on Weds. and it has been running around 110 every night this week. I did go last night it was 109, when I left, but overcast. It is projected to go down tomorrow to right around 100 as a high.
