Detox before surgery for preparing your liver for drugs overload

I had been conscously losing weight for 5 mths before surgery after cancellation due to covid. 1 lost 17kg but wanted just a little more. The weekend before I did a 2 day detox where I drank only coconut water for the 2 days. I lost 2.5kg and my surgeon said the extra loss of fat round my abdomin made her job easier. My recovery has been incredible with no pain and no gas pain either, and none of the expected side effects.. Then I discovered an article that said detoxing before surgery prepared liver and kidneys for the onslaught of anesthesia drugs and should make it easier to dispel the new toxins. I believe this worked for me, may not work for everyone but definitely worth a try. I also drank warm water with sliced lemons and fresh mint, that i took from home, from the time I was out of recovery. I believe this also helped dispel the gas. Hope this helps someone else.
