Feed you to death over a year. You watch your body run to ruin and die of sheer obesity.
Please, been there done that, and I'm still alive.
Starved to death for every single day you live, but fed just enough nutrients to continue living, and protected from disease and other ailments that would kill you due to a weaker immune system that has began to fail with your continued starvation, though whatever you are fed you don't feel it as it is so small over such a long time it feels empty the entire time. Restrained to this table of eternal starvation, you shall die a 'natural' death of old age, but for every day since your restraint (something like 50-70 years) you will experience a hunger that never ends, and a thirst never quenched, while wracked with non-lethal diseases that serve as annoyance's to your miserable existence.
Beat that!
