It definitely belies a level of privilege that some people must intentionally seek out discomfort or pain in order to begin to even approximate the agony others are inherently forced to live through. I don't believe privilege is itself a moral failing, or we're stuck with whole categories of 'original sin'. It's what objectives its used to enable that potentially indict those that possess it.
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?
That’s not a weight-loss plan though, that’s a fit-back-into-your-current-wardrobe plan. People with “weight problems” are generally on an upward slope and a point source puts a notch in the graph, it doesn’t zero the slope or take it negative. What it does say, if anything, is that there are factors we can control that moves the needle, but they are the journey not the destination.
There are some fat people for whom hunger is instant and incessant and a constant distraction, and perhaps losing 5 years of life at old age is worth it.
For other people, maybe someone who's 20 lbs overweight and would like to be able to play with their kids without running out of breath, maybe the annoyance of being hungry isn't actually that bad for them.
Pain is subjective. One person's excruciating pain - the same stimulus could be a mild annoyance to someone else. I've been tattooed for 6 hours and was able to easily distract myself and laugh while listening to a comedy podcast, other people can't handle holding their finger over a flame for more than a millisecond or can't eat a hot slice of pizza out of the oven.
Pain and annoyance and discomfort can also be acclimated to. What might be really difficult and distracting might become something you get used to and learn to tune out. But then again, to be fair - maybe not. Maybe for some people that hunger is not something they can learn to live with.
