Discrimination is the action towards another of a certain group or category. It is not based off the person alone, but the group that someone categorizes them in.
In an article by USA today, weight discrimination is discussed. Weight discrimination especially in women is increasing and is nearly as common as racial discrimination.
“Reported discrimination based on weight has increased 66% in the past decade, up from about 7% to 12% of U.S. adults, says one study, in the journal Obesity. The other study, in the International Journal of Obesity, says such discrimination is common in both institutional and interpersonal situations — and in some cases is even more prevalent than rates of discrimination based on gender and race. (About 17% of men and 9% of women reported race discrimination.)”
