BlubberPatrol has a section where you can enter the foods you normally eat, so you can just check off the ones you ate that day and have it total them up for you. Most diet gurus will tell you not to weigh yourself each day, but that's not a good idea. Your weight can vary by a few pounds from day to day from water retention and dehydration. If one day, you eat some pizza, with lots of salty cheese on it, your weight will probably go up substantially the next day as your body retains water. Or if you have a lot of caffeine or alcohol one day, your weight will probably drop substantially the next day since both are diuretics.
Water is very heavy.
So, if you are only weighing yourself every Monday morning, one Monday, you may be lighter due to dehydration, and the next Monday you may be retaining water because of the pizza you ate on the previous Sunday. So, even if you dieted all week, and really did lose some fat, you may actually weigh more. The best way to deal with this is to weigh yourself every day and then compare your average weight . This is the principle around which BlubberPatrol is designed. If you take a minute to enter your weight each day, BlubberPatrol will show you graphs with your average weight over periods of a week, month, quarter, or year.
