The statement is True.

Explanation:

If you want to lose a pound, you should aim to reduce calories from your diet over it. Such as in one week there should be a deficit of 3500 calories, which means you should take 500 less calories daily in order to lose one pound in a week. 3500 calories constitute one pound. If your calorie recommendation is 1500 calories per day, then you should take 1000 calories in a day in order to have a deficit of 500 calories from your recommended calorie intake. This will result in losing one pound in a week.
