As a thin person, you might have to learn to live with sexual urges that you cannot act on, on violent urges you cannot act on, on urges to scream at your boss for being a moron or better yet just walk out and never go back to work that you cannot act on.
Some of those urges may be stronger for some people than for others.
The same way that urges of hunger can be experienced differently by differently people (at both a signaling hormone / chemical level as well as a psychological/willpower equipment level).
Are you suggesting that the feeling of hunger experienced by overweight and obese people is universally a higher standard than any other discomfort or natural drive humans experience?
