You weight 290 pounds and you want to lose 100 in six months how many calories do you need to burn per day?

It takes 3,500 calories burnt more than are consumed in a day. To lose 100 pounds, that means that 350,000 calories need to be burnt. The average month has 30 days in it, so 6 months is 180 days. That means that you would need to burn about 2,000 (1,944 calories, to be exact) a day more than what you consume. So if you eat 1,200 calories a day, you then need to burn off 3,200 calories every day.
