Shouldnt large people be jacked just from simply moving around with the extra weight? Im talking about muscle mass here and not fat content. Thanks

In absolute terms they’ll have more muscle mass, yes.
A lean, athletic 65kg person who consists of 42% muscles has 27kg of muscle mass. A fat 120kg person is going to have something like 35% muscles, even when sedentary. That’s 42kg of muscle mass. That’s why heavier people can generally lift more weight (again, in absolute terms. And keep in mind that training can improve the efficiency of muscles a lot). However, while the 65kg person probably has something like 10% body fat (6.5kg) the fat person will have something like 40% body fat (48kg). That’s why they still look very fat and it’s still unhealthy.
