Following Wishnofsky's model, how many calories daily would an individual have to be in a deficit of daily to lose a pound per week?

To lose one pound of body weight, an individual must create a calorie deficit of approximately 3,500 calories. According to Wishnofsky's model, if someone aims to lose one pound in a week, they would need to establish a daily calorie deficit. By dividing 3,500 calories by 7 days, the calculation results in a daily deficit of about 500 calories.

This information underscores the importance of understanding how daily caloric intake and expenditure influence weight management. A deficit of 500 calories each day can lead to steady, sustainable weight loss, making it a common recommendation in dietary and fitness planning for those targeting a one-pound loss per week.
