Well it's unhealthy ? especially since your body probably burns that off from just simple daily activities.
The fuck if I know I'm not a dietitian. All I know is girls need like 1,000-1,200 calories a day. So..
Within a healthy balanced diet, a man needs around 10,500kJ (2,500kcal) a day to maintain his weight. For a woman, that figure is around 8,400kJ (2,000kcal) a day.These values can vary depending on age, metabolism and levels of physical activity, among other things.
