This actually proves my point. “Very little alcohol enters fat because of fat’s poor solubility.” Meaning alcohol doesn’t enter fat, so body fat doesn’t lower the concentration of alcohol in the bloodstream. It’s part of TIPS certification; a lot of bartenders are taught that body weight increases your ability to consume alcohol, so they see a heavy set guy and assume he can handle more alcohol, but fat doesn’t actually affect their tolerance. A 5’8" fat guy that weighs 250 is going to have a lower tolerance than a 6’2" lean guy that weighs 250.
