I used the website www.sparkpeople.com. I needed to lose 30 pounds, two babies and then junky eating.
When I used it, it was free, help you design a program for you, as far as calories and exercise. You put in how much you want to lose and in what time frame not more than 1.5 pounds a week.
Then you track your calories...they have every food known to man in their calorie data base. And they just count the calories apple or oreo they don't judge what you eat just tell you the calorie count and subtract it from your days number of calories.
You can also track your exercise if you do 30 minutes of cardio...plug it in...walk 10 minutes, put it in...it also rewards you will streamers and such for drinking 8 glasses of water a day as well...
There are great forums for book lovers, dog lovers, grief support groups, those that are losing the same amount of weight as you, etc etc etc...
I lost those 30 pounds and haven't looked back...good luck...oh, and it was all free...did I mention free??
