One gram of sugar has 4 calories, according to Santa Clara County Public Health, so 60 grams of sugar has 240 calories. To burn the calories from 60 grams of sugar, a 160-pound person can do low-impact aerobics for 40 minutes or high-impact aerobics for 30 minutes, according to Mayo Clinic.
Mayo Clinic points out that calorie expenditures vary with an individual's weight. Heavier people burn more calories, so they can burn the targeted 240 calories in less time. Choosing a particular workout or activity over another also affects calorie expenditure. Running burns more calories than walking, so a person needs to walk longer to burn 240 calories compared to a person who is running.
