No, you just don't know science. Let's just say for example Choji and Hiruzen both weigh 140 lbs hypothetically. For Choji, who starting off in the series was 4'9 ft and 5'1 ft by the end of part 1, he would need to take in about 1900 calories a day with no exercise to maintain his weight. Hiruzen in his prime would need about 1800 calories with no exercise. So they both have around the same amount of calories intake a day. Therefore Hiruzen has enough calories to perform the same jutsu that Choji could perform.
