This is claimed in Sweden's second-biggest newspaper.
My translation: "I have started to short-term fast.[...] The reason is that lots of world leading scientists that study aging and the brain has implanted in me that this is the best and cheapest method apart from exercise to maintain a good health."
The idea is to stop eating for 16-20 hours "a few times per week". Water is ok, no nutrition is allowed.
This is claimed to increase the brains production of BDNF. Decreasing overall intake of calories with 20-40% of current rates supposed to be beneficial against dementia, cancer and heart-disease. The reason is claimed to be that our cells go into survival mode when we lack energy, this in turn executes a bunch bodily functions that are beneficial to us.
They also claim nothing can go wrong because our ancestors did this for millions of years. And the reason nobody talks about this is that drug companies are evil and greedy.
They claim 700 scientific articles support the claim. No sources though.
Could someone point me to any scientific sources that support this claim?
