After tediously tracking calories and willfully shunning cravings, many a dieter has likely dreamt of a simple switch that, when thrown, could shut down hunger and melt away pounds—and scientists may have just found it.
The “it’s your own fault” view of obesity as a willpower issue does not hold up to logical scrutiny.
As far as I know, obesity is the only condition that has massively increased in humans, despite an overwhelmingly negative view of it by society, and shaming of sufferers. Look at smoking as an analog–despite how difficult it is to quit smoking, people have done so in huge numbers over the past few decades, while obesity has continued to rise, unabated, throughout the world. If it were a willpower issue, as smoking apparently is, we would most certainly not see this happening.
