Here's a website I found that is a great resource. it's free, but there's a lot of ads.
http://www.fitday.com/?404;http://fd-wi ... t/Home.aspYou can keep a food log [it tracks the nutritional value], and an exercise log [it tracks calories burned] in addition to keeping a running weight graph.
Several years ago I lost about 60 lbs by following a low-carb [South Beach] diet. I was still 20 lbs short of my goal weight when my adult grandson came to live with me 2 1/2 yrs ago, and I was forced to consider his preferences [not just my own] and bring bread and potatoes and other similar previously banished stuff back into my house. I had already regained some of my lost weight and then I quit smoking 3 months ago. I'm now up to 20 lbs regained in addition to those 20 I never lost in the first place, so I need to lose 40 lbs. I'm going back to my low-carb eating regimen.
To add a little perspective, I now weigh almost exactly what I weighed 42 years ago - when I was 8 months and 3 weeks pregnant with my 2nd child. Except it's not "baby weight" I'm carrying now!
