I recommend the following vitamin c powder. If you are up for it you can do also a vitamin c cleanse: https://www.perque.com/product/perque-potent-c-guard-powder/
Catabolysis and heart damage is also possible. The body will consume fat first, so this is an avoidable outcome. I added the multivitamin and calcium/magnesium/zinc supplement to help avoid damage as well. Damaging my heart is my largest concern with this diet.
If you're fat, you shouldn't ever be hungry, but eating food actually makes you go through cycles of hunger.
Stop eating altogether you get a steady hormonal state that is never hungry (until your fat reserves deplete).
Feeling "full" means overeating.
I read a comment on reddit once: "hunger" is telling you when to eat, not how much to eat.
It's very dangerous, and I wouldn't recommend it to anyone who hasn't put their body through extreme circumstances in the past and knows their actual (not percieved) limits. I haven't pooped in a week, and my last bowel movement was gnarly.
A safer rate of weight-loss should not be more than 2 pounds a week, or approximately a 1,000 calorie defecit per day. An online search for a basal metabolic rate calculator should be a starting point.
Advice to others, no matter what process you take: I recommend not weighing yourself more than once a week - it's a mental thing.
