4. A slender and restricted diet is always dangerous in chronic diseases, and also in acute diseases, where it is not requisite. And again, a diet brought to the extreme point of attenuation is dangerous; and repletion, when in the extreme, is also dangerous. 5. In a restricted diet, patients who transgress are thereby more hurt (than in any other?); for every such transgression, whatever it may be, is followed by greater consequences than in a diet somewhat more generous. On this account, a very slender, regulated, and restricted diet is dangerous to persons in health, because they bear transgressions of it more difficultly. For this reason, a slender and restricted diet is generally more dangerous than one a little more liberal. 6. For extreme diseases, extreme methods of cure, as to restriction, are most suitable. 7. When the disease is very acute, it is attended with extremely severe symptoms in its first stage; and therefore an extremely attenuating diet must be used. When this is not the case, but it is allowable to give a more generous diet, we may depart as far from the severity of regimen as the disease, by its mildness, is removed from the extreme. 8. When the disease is at its height, it will then be necessary to use the most slender diet.
