@ChuckKnock is right that comparing the number of weight people gain on certain stuff is not a fair comparison.
There are just WAY too many variables that come into play. Genetics, workout, diet, etc. For example, someone could eat junk food and gain A LOT while others could gain only a few lbs but all lean muscle and in the end, the latter receives more results because he managed to gain muscles, but the first one managed to gain only fat, for example. Also, there are people who are 250 lbs naturally, but there are others who can barely get over 170 lbs naturally.
