Fasting Update 2

Okay, I’ve been doing some fasting over the last two weeks. Monday and Tuesday each week I ate bugger all, and on each Wednesday did not eat till the evening one week and the afternoon the next, so effectively 72 hours and 68. I also fasted on the Thursday of the first week and on the second ate late in the day. In between times I was eating less than my (supposed) base metabolic rate (BMR).

Here’s some stuff I’ve learned: It made no difference to my ability to exercise. Water loss could be lot and cause large variations in weight. Ketosis was variable but certainly kicked in more on the second week; ketosis is also not a good measure since it too varies with exercise or hydration. Drinking an electrolyte consisting of salts of sodium, potassium and magnesium certainly makes one feel better, it also kills hunger somewhat. At the end of this time my ‘fed’ weight was a minimum of 6lbs lower.

Over the weekend I ate plenty on the principle that my body needed materials to rebuild itself, also because constant dieting is not good for insulin resistance. I did eat nasty carbs (crumpets in the mornings) but that was about all. The rest of the food was veggies, salad and protein. I noticed over the weekend a delay in weight loss. On Saturday morning I was 182.6lbs yet, on Sunday morning after eating on Saturday, I was down to 181.6. On Sunday I ate a lot, finishing off in the evening with rather a lot of preserved sausage (I shouldn’t have) and this morning my weight was 184.4lbs.

I hit the gym early then came home prepared for another day’s fasting. I abruptly felt very tired and light headed and ended up having a snooze at 9.00AM. But then I didn’t sleep well the night before, getting just five hours. Even after I woke I still felt light headed and weak. I checked if I was in ketosis and found I wasn’t. A half litre of electrolyte and a cup of oxo gradually pulled me out of this. I did my 2,000 words.

I’m now interested to find out how much I’ll weigh tomorrow morning.
