Karen - My goal is 10 pounds by the end of the month, too. I'm going back to counting calories. When deciding on how many calories, you have to look at how much exercise you're doing and your own personal metabolic rate. If you're one who loses easily with minimal exercise, you can eat more calories each day. I can lose, when I stick with it and exercise at least 5 times a week (at least 30 minutes a day), but it doesn't have to be hard core exercise (I couldn't run a mile to save my @$$). Anyway, I was eating 1600 calories/day. The main goal is to burn more calories than you consume. Good luck figuring that out exactly. I know there are charts out there that tell you how many calories are burned from a certain activity. Maybe this will help...
