If you consume one 12 ounce can of regular (sugar) soda per day, the excess calories will amount to about 15 pounds per year. One ounce provide 12 calories, thus 12 ounces will have 144 calories. 1 year has 365 days; thus there will be 365 × 144 = 52560 calories in a year. However, 1 pound is equivalent to 3500 calories; hence; 52560/3500 = 15.017 pounds
