68-Hour Fast again

[S11m]

I have just completed my regular 68-hour fast. I fit fasts in between scheduled meals - and I have an Age Concern meal alternate Fridays - so I have been fasting every four weeks.

Once you have exhausted your glycogen reserves (about 2,000 calories) you can only exercise at the power determined by the rate at which you can assimilate energy from fat less your Basal Metabolic rate. When you exercise you might get a bit hypoglycaemic and need to slow down or rest - but I would have thought that one's blood glucose levels would have been topped up overnight - but I am not feeling very energetic this morning. I broke my fast with 500ml of full-fat live yoghurt as usual, as it is carbohydrate-free and will re-populate my gut biome.

Last time I think I exercised too much in hot weather 48 hours into the fast - so I exercised less this time. Every time I fast there has been some complication - like two heatwaves and the hot weather yesterday. On Wednesday I had my flu jab and shingles vaccination - and I am wondering if that is significant.

I ate a bit more last week, and got three pounds above my target weight - and the morning I was two ponds below - so I think I am on target. Last time I fasted Thursday to Sunday I was back stable at my target weight by the Tuesday.

How are you all getting on with your fasting?

Hi

I'm getting on well thanks. I have done 2 v long runs (2hrs 45) in a fasted state now. I also, inspired by your longer fasts, tried my first 24hr fast for 28yrs last Friday. I was very pleased with how it went and hope to repeat it.

Like your age-concern meal, I have quite a few things which get in the way of longer fasts, mostly we try for our 4 small boys to always eat with one of their adults (ideally both!) so it takes a bit of juggling as you can imagine!

Great, Stoozie

I have difficulty running across the road - fasting or not!

You were fasting 28 years ago! I would sometimes not eat for a day or two if I had gastric flu. I am glad your 24hr fast went well.

My one "small boy" is 41 now - so I think you might be younger than me!

I am feeling great today, and my HRV (which quantifies potential longevity) is way up.

Yay!

If I do not eat, my blood pressure goes in my boots,twice I have collapsed and ended up in hospital. So I do not think this would work for me.
