To lose 1 pound, you need to burn how many extra calories?

• A. 2,500
• B. 3,500
• C. 4,000
• D. 2,000

Answer: (B)

Weight loss happens when you burn more calories than you take in over time. A widely used estimate is that about three thousand five hundred calories equals one pound of body fat. So creating a total deficit of roughly three thousand five hundred calories will tend to produce about one pound of weight loss. Keep in mind it's an approximation—individuals vary due to metabolism, water changes, and how the body uses fat. For a practical plan, many aim for a daily deficit of around five hundred calories, which would lead to about a pound lost per week if kept up. The other numbers would imply faster or slower loss than this common rule of thumb. In short, the number used to estimate one pound is about three thousand five hundred calories.
