What is your SparkPeople recommended calorie range? How many pounds of weight loss per week have you set for your program? 1500-1700 calories could be a little low, depending on the range the program gives you.
I agree that no one needs to exercise for 1-2 hours a day unless they are training for some kind of endurance event. It can actually make weight loss more difficult if you're doing a ton of exercise. Quality is more important than quantity when it comes to your workout. As long as you are establishing habits you can live with forever, that's what matters most.
