It's a bit of a paradox for the artist, if he draws them accurately then fats get offended, he can only appease the hamplanets by drawing something less fat. This artist is also using a method called subtraction where he is drawing some parts of the body smaller (hands, waist, legs, neck) to exaggerate others (head, shoulders, hips). He is also using the same outline that a thin person would use to get a more human look instead of a realistic fatty one. Ironically the fat acceptance community won't accept realistic portrayals of fat people, so you probaby aren't going to see them making art like this any time soon.
