If a person burns approximately 500 kcal per 45-minute jogging session, how many such sessions per week are required to produce a 3,500 kcal weekly deficit (approximate 1 lb/week) solely via jogging?

• A. 14 sessions per week since you must double sessions to account for post-exercise compensatory hunger and the inefficiency of exercise for weight loss
• B. 0 sessions because exercise never contributes meaningfully to energy deficit and only diet matters
• C. 7 sessions per week (about one 45-minute jog each day)
• D. 3 sessions per week because the body continues to burn calories after exercise indefinitely and multiplies daily deficit

Answer: (C)
