I believe this to be true. To put it onto perspective: To lose 2 lbs of fat per week you must strip 7000 calories from your person. That might mean, on average, eating 500 calories less than you usually do each day, and excercizing to burn 500 calories each day for 7 days. This is why it's hard to lose much more than 2 lbs per week and keep it off!!
