Don't listen to anyone - have your own opinion based on personal experience. Test 5 daily weekly fasting (if you are not sick - nothing will happen to you!), Observe yourself and draw your conclusion.
Once a week, 1 day is worth starving - do not eat anything for a day, take my word for it, nothing terrible will happen, but you will correct your health, how much food a person eats all day today - this is * , so go ahead, better on YouTube sometimes - there are a lot of raw foodists and low-food eaters, they will better explain to you😎😎😎 (I spent a ski train on starvation, dashed off 20 km - ease and freedom!)
There are much better ways to make yourself healthy for example: Sports, healthy eating, active lifestyle, blood donation (moderate), Rest in sanatoriums. Will be more effective than a hunger strike. From personal experience, my grandmother was starving and it did not bring anything good. Only depletion of the body
