its not age im in my 20's! i like the sound of water fasting although does taking medication count as eating? im also anaemic so it might not be such a good idea? and if i lost as much as weight as people are claiming can be lost through these fasts i would fall under the underweight category i just googled ketosis, i eat normally alhamdulillah i don't think its that i do sometimes have low bp it could be that i suppose, there isnt much that can be done about that apparently, my doc said you just have to wait until your artieries get all clogged and then ur BP will rise automatically
