What should my calorie and kilojoule intake be in order to lose at least 1kg /2.204lbs per week along with exercise?

2 pounds ~ 7000 cal. So to lose two pounds per week, you need to create a caloric deficit of 1000 calories daily through calorie restriction and increase in exercise. With cardiovascular exercise daily, you can burn the majority of this amount, and a reduction in calories of a few hundred daily will make up the rest. Don't over-restrict calories, add exercise instead to stay healthy and energetic.
I need your height. The whole calculation is based on your height. A good nutrionist can help with that calculation.
