Connecting the dots: https://yellowstonebearworld.com/how-long-do-bears-hibernate https://yellowstonebearworld.com/how-long-do-bears-hibernate "Grizzly bears typically hibernate between five to seven months" https://en.wikipedia.org/wiki/Angus_Barbieri%27s_fast https://en.wikipedia.org/wiki/Angus_Barbieri%27s_fast "Scottish man Angus Barbieri (1939 – 7 September 1990) fasted for 382 days (...) 207 kg to 82 kg" That's 327g per day so a modern human need about 59kg of added fat to survive 6 monthes without eating or hibernating , while being fully able and functionnal in case some additional food can be found during the time. As an anecdote my longest fast was 8 days, and I recorded between 300 and 400g of weight loss per day. I was walking a few hours per day without any trouble, so no loss of physical energy.

> For 382 days ending on 11 July 1966, he consumed only vitamins, electrolytes, and zero-calorie beverages such as tea, coffee, and sparkling water, although he occasionally consumed small amounts of milk and/or sugar with the beverages, especially during the final weeks of the fast. That's an apples to oranges comparison with hibernation. Your body needs some vitamins to process body fat into energy.

  It's unclear wether vitamins and electrolytes supplements were necessary or not during this fast. If you read the paper: https://pmj.bmj.com/content/postgradmedj/49/569/203.full.pdf https://pmj.bmj.com/content/postgradmedj/49/569/203.full.pdf It looks like supplements were not given continuously. I'm not an expert but some doctors on youtube point to studies which show stable levels of many things during extended fasting: https://pubmed.ncbi.nlm.nih.gov/9374844/ https://pubmed.ncbi.nlm.nih.gov/9374844/ https://thefastingmethod.com/vitamins-and-calcium/ https://thefastingmethod.com/vitamins-and-calcium/ Fat, liver, kidney store lots of useful things. Some things like salt are easy to find all year anyway, they don't run away :).

Wow a man lost 276 pounds by eating nothing for a year. It's amazing what the human body can do. He's also living proof that you really can't go wrong with dieting, if you're obese. Eating nothing is theoretically the worst diet possible (aside from maybe eating poison) so it's like it's like whatever crazy thing works for you, just do it.
