That's not really close to true, at all. As someone standing at 180cm, my basal metabolic rate is about ~1,300 calories[0]. That's assuming I weighed 40kg. A healthy weight for me would be considered to be between 60kg and 80kg, which would put my basal metabolic rate at 1,600-1,800kcal.

Not everyone can be 5'3".

I am 173cm (5'8.5"), 65kg. I also run three 8km's and two 5km's a week with a 4:20-5:00/km pace. I do this on at or about 1200-1500 calories. And I still have fat. I am not a flat bellied skinny person either.
