Those are so lovely @Fullsteamahead
As I am off work here are my fasting notes so far @loveyouradvice
Fung and Ramos Facebook group suggest optimum for weightloss is 3 x42 or 2 x 48 a week!!! Each 42- 48 hour fast should be followed by at least 3 meals which are satisfying and nutritious with no snacks before starting the next fast. I don’t plan on doing more than 1 longer fast a week.
All the groups I am on seem to suggest it is best to vary fast lengths and not eat omad everyday for extended periods of time unless it is a pattern that works for you for long term maintenance. One work around is to alternate between 30 hours, then a meal, 16 hours, then a meal and repeat. Usually advice seems to be to have 1 day a week at least without fasting to keep body on its toes!
Fasts of 48 hours or less seem to be ok for unsupervised fasting but longer fasts brings more risks from refeeding syndrome etc and should be researched and prepared for - possibly with medical advice. 3- 5 day fasts should be restricted to a couple of times a year according to Mindy pelz. However 72 hour fasts are done weekly by a small number of people on the ramos fung group - or more commonly once a month.
fasts of over 24 hours can include a pinch of Himalayan salt every few hours. Do not supplement potassium unless included in pre prepared electrolytes suitable for fasting - I haven’t found out about these yet.
(Below mainly from mindy pelz and fasting apps- all these times vary from person to person)
4 hours - insulin drops
8 hours - blood sugar normalises
12 hours ketosis begins
13 -15 hours autophagy begins (reduces inflammation and stimulates cell renewal)
18 hours fat burning begins (once this starts hunger should reduce so for me I think it is approx 21 hours)
24 hours - beneficial for gut - triggers creation of intestinal stem cells
- in addition cell regeneration or autophagy is increasingly happening (helps with effects of ageing)
48 hours - growth hormone (muscle building) is 5x as high as at the start. This can promote wound healing
54 hours - increasingly insulin sensitive
72 hours - breaking down old cells and creating new ones
96 hours - metabolic reset (dr fung) can help undo the effects of previous low calorie diets
Dry fasting for 12 hours may be beneficial for the brain, lower inflammation etc can be helpful for arthritis (mindy pelz) don’t do this for longer than 24 hours.
