At my place of work as a student trainee, my attention was called to a patient who has suffered badly from secondary diseases.

  • He has a Body Mass Index of 42, obese.
  • He also suffers from Type 1 Diabetes (Insulin dependent)
  • His blood vessel walls have become narrow, causing an increase in blood pressure (Hypertension)
  • He has Chronic Kidney diseases: bowman capsules are not able to filter his blood properly because of the pressure.

Can this Patient be helped by a diet? We would have to place him on:

  • little carbohydrates because of his obese stature and diabetes
  • low salt because he is hypertensive
  • low protein because of his Kidney disease

Yet what's left to eat if valid nutrients are not to be put up for consumption?

  • Well, low salt still means sufficient salt to live, but nothing more. Same goes for carbohydrates - you won't starve an obese patient to death! – Narusan Sep 30 '18 at 21:18
  • @Narusan - Yes, actually, you can. In the absence of food, life threatening starvation occurs around 40-50% of weight lost. Fatal in 8-12 weeks with no food intake. Less if no water intake – JohnP Oct 1 '18 at 17:00
  • @JohnP Sorry for that misunderstanding: I meant that any diet for patients - no matter how severe the obesity - will still have to cover the bare minimum. That’s what I meant by „low salt still means sufficient salts to live“. Likewise, low calorie intake should never be starve them to death. Therefore, even on a low carbs diet, they can still it carbohydrates, albeit maybe just the bare minimum. – Narusan Oct 1 '18 at 19:21
