Tamāla Kṛṣṇa: when one has no energy, when one has no strength, then it's hard to be active. But then the other thing is true, that when one is active, he gets appetite automatically.
Prabhupāda: Therefore those who are physically active, they can eat more.
Tamāla Kṛṣṇa: Yeah, it's true.
Prabhupāda: But those who are not physically active, they cannot eat.
Tamāla Kṛṣṇa: No. That's the difference between the Bengalis and the Punjabis. Punjabis work very hard.
Prabhupāda: No, they eat also.
Tamāla Kṛṣṇa: And they eat very nicely.
Prabhupāda: They are healthy men.
Tamāla Kṛṣṇa: The Bengalis, they do a lot of clerical jobs, sitting in one place.
Prabhupāda: They get diabetes.
Tamāla Kṛṣṇa: Really?
Prabhupāda: No, no, not the Bengalis. Anyone who cannot physically work, they eat sitting, and it is not digested, and therefore the diabetes. Diabetes is caused by eating more which is not digested. They say it is medically proven, and that's a fact. And tuberculosis is the wasting disease. As much food he requires, he'll not get.
Tamāla Kṛṣṇa: What is that about tuberculosis?
Prabhupāda: As much food he requires, he does not get.
Tamāla Kṛṣṇa: Starving.
Prabhupāda: People do not get nowadays proper nutritious food.
Tamāla Kṛṣṇa: Tuberculosis. And diabetes, getting the food but not digesting.
Prabhupāda: So if we remain nice, then digest; or anyone who works, brain work, that is nice.
