"Prof. Martínez de Victoria insists that the best way to control body weight is to combine a limited food intake with regular physical exercise. In this sense, he states that with a 500 to 700 calorie deficit, depending on body weight, age and physical exercise, a person can gradually lose 6.5 lbs a month..."

This is a numerical impossibility. (see here and here)

Time to invade them again so they stop spouting this nonsense.
