ISKCON gurus consume too much sugar and ghee and they do not get enough physical activity.
Srila Prabhupada requested that ISKCON use raw sugar if possible, but ISKCON continued to use processed white sugar and too much ghee and butter in the diets of the devotees.
ISKCON gurus could use a little yoga discipline and a lighter diet than is offered the deities.
If devotees want to eat like the deities, then they will eat too much sugar and ghee.
The lifestyle of ISKCON gurus is too relaxed and lazy.
They need some physical exertion.
I heard a narration about Srila Prabhupada walking through Balboa Park in San Diego with some disciples when they came upon some yogi type doing yoga exercises.
The disciples sort of snickered and scoffed at this individual and expected Srila Prabhupada to criticise this yogi, but Srila Prabhupada acknowledged this yogi and said "this is good health".
So, yoga as a process of self-realization might be terribly deficient in this age, but yoga as a healthful discipline is very good.
