You are correct, sir.  However, your numbers are based on your weight (I assume), and as such does not compute to hambeasts.  In order to lose 5 kg (get with the rest of the world and Lincoln Chafee and use the goddamn metric system) you need to have a calorie deficiency of 35 000 kcal (that is correct on your part). If you weigh 140kg (308 lbs), are 177cm tall and are 35 yo. you have a base kcal consumption of about 2631kcal. In order to lose 35 000 kcal you have many options. You can consume 1800kcal a day and burn 831kcal a day, getting you to your goal in about 43 days. This involves you being hungry most of the time. Suck it the fuck up.
