If a person only drinks water and eats glucose, how long could they survive before getting any symptoms? When would the damage become irreversible? When would that person die from lack of minerals, proteins and vitamins? Also, can this "process" be sped up by drinking distilled (pure) water?

  • $\begingroup$ You may want to look at so called "Muselmann" created in german concentration camps, becasue their diet consisted of nothing but carbohydrates(vegetable broth and bread) and water. Protein deficiency seems to be the most important factor. $\endgroup$

    $\begingroup$ According to WP, symptoms of vitamin C deficiency (scurvy) will appear after 1 month. $\endgroup$

  • $\begingroup$ @John Actually there's at least one study I'm familiar with where a 27yo male fasted for 382 days with no ill effects (ncbi.nlm.nih.gov/pmc/articles/PMC2495396). He had vitamin and nutrient supplements but no protein. I'm pretty sure the cause of death will be related to a vitamin deficiency. $\endgroup$

  • $\begingroup$ What about vitamin deficiencies that weaken your immune system and tend to lead to death from infection? Would those count? $\endgroup$

    $\begingroup$ The type of sugar matters a lot in this case, since muscovado, jaggery or other non-centrifugal cane sugars contain vitamins and minerals (en.wikipedia.org/wiki/Muscovado#Nutrition). $\endgroup$
