ImpactModerate impact

Abstract in brief

  • The 27-year-old male fasted safely for 382 days under supervision, maintaining his normal weight and showing normal blood glucose and insulin responses, even after a long period of fasting.
  • During the fast, his blood glucose stayed around 30 mg/100 ml, and despite some fluctuations in electrolytes like potassium, magnesium, and calcium, he remained healthy with no significant health issues, and these levels normalized after refeeding.
  • The study suggests that extended fasting can be done without harm if properly monitored, as observed with this patient, who experienced temporary electrolyte imbalances that corrected over time and showed no long-term negative effects.]

@MobileTap @leadlagreport 3/3 Therefore, it’s highly misleading to use that medical experiment as a reference for how solo (ie without medical supervision) fasting can be done healthily, esp as that experiment was rather targeted “low calorie eating”. https://t.co/WLZ8vD0lFG https://t.co/7p5XeBr2sz

Nippelitietoa siitä pitäville. Yksi pisimmistä paastoista kesti 382 päivää. Valvotusti suoritetun paaston aikana potilas joi vettä ja sai hivenainelisiä. Paino tippui 207 kg -> 86 kg.

Tämä ei ole suositus, mutta "täysi syömättömyys" onnistuu kyllä. Aikanaan pisin paasto oli 382 päivää, jonka aikana potilas sai vain hivenainelisiä. Ammattilaisten valvomana suoritettu.

@katebernie0707 They can yes :-), the longest fast ever recorded was for 382 days. They did end up taking vitamin and mineral supplements while water fasting. Other Centers can also supervise a water fast for up to 40 days. Youtube also has lots of docuseries on these https://t.co/I6dOoU9Cmd
