As you can see from the graph, weight loss was rather startling, I think I’ve lost 1.5kg of water weight and a further 1kg of fat, which together produced a frightening drop in scale weight.
My appetite’s been pretty much non-existent. There’s a pot of delicious stew on the stove and I’m not much interested, and I’m having trouble finishing mugs of coffee and cream even though they taste fine at first.
I’m usually against counting calories, but I can tell you exactly what I’ve eaten this week: 1500ml of double cream (7005kcal), 1kg of 80/20 beef (2730kcal), 1 packet of butter (1862kcal), and various vegetables that don’t add up to much.
That’s 11597kcal in total (+/- 10% because food labels are rubbish), or 1656kcal/day.
I’d say I’m moderately active, walking and cycling everywhere but nothing on top of that, and I’m 55 years old, 5’10” (178cm) tall, 95kg.
ChatGPT uses some made-up formula to translate that to 2780kcal/day, and that means I’m in a 1124kcal/day calorie deficit.
7868kcal deficit over the week translates almost exactly to 1kg of fat loss.
See, it’s all just CICO!
I notice that I am not confused. Weight-wise everything went exactly as predicted and in accordance with the laws of physics, which as a rational man I am morally obliged to obey.1
Other predictions:
> Mild headaches on ketosis entry, so a few days of keto-electrolytes to moderate this ‘keto flu’.
I did get a sort of ghost of a headache on the first day, which reminded me to take the electrolytes, and then it went away, so apparently I can go into ketosis with hardly any trouble these days.
> Non-existent appetite, rapid weight loss
Spot on. Haven’t been hungry all week. Mainly eating because I thought I ought to.
> excellent mental clarity,
Generally speaking yes, but on the third day I felt sluggish and fatigued, and took a nap at 1630 for two hours, after which I felt fine.
And then on the fifth day I was either sluggish or underslept (kept up till 0130 the night before by bad fluffies) and also a bit virusy. So I went to bed at 1630 again feeling shagged, but it didn’t work and I got up about half-an-hour later with full keto-clarity restored and stayed up late singing with a friend from choir (which is where the whisky I forgot about earlier came in).
> the “two fuels” problem where I can get my mind tired while still having plenty of physical energy.
Didn’t happen. The two times I felt tired it was body and mind together, I didn’t get the weird feeling where my mind was tired but my body was full of energy.
> If any of these things don’t happen I’ll be surprised.
I am in fact surprised. My ‘glycolysis is blocked’ idea implies that if I don’t have any carbs to burn I should feel fine all the time, whereas actually although I mainly felt all bouncy and energetic and full of keto-clarity, on two days I felt tired, and that shouldn’t have happened since I dumped all my carbs over the first few days.
I can make excuses in retrospect, but I’m not going to. It’s important to notice when your predictions don’t work out. I notice that I am at least somewhat confused, although not enough to change my mind about any of the things.
Still, ex150ish worked again, so that’s now nine times out of ten, Laplace tells me I should now have 10:2 odds or 83% confidence that it will work for me in future.
I could happily carry on with this for another week, but I’m not going to, my most recent weekly organic veg bag contains some nice-looking apples, and the plan was to change to ex150+fruit at some point, to check that that still works, so I’ll do it now. As well as the apples I’m going to restore my usual breakfast of defrosted frozen red fruit, which I’ve been missing, only with cream instead of the usual yoghurt.
I expect this to work, to lose another kilo of fat over the next week. At about 66% confidence since it’s worked for me once and never failed.
Water-weight wise I’m not sure what happens, there’s probably not enough carbs in that (about 30g/day) to take me out of ketosis so I’ll probably keep the water weight off, not sure what it will do to the mental clarity thing, although since that wasn’t reliably working anyway who knows?
Time will tell…
I also reckon I’ve got room to push my thyroid dose a little higher, my waking temperatures are now about 36.7C, still a smidge low according to Barnes, and the point where I top out, the graph looks clipped, and I start overheating seems to be about 36.8C these days, so I might try putting the dose up a tiny bit and seeing what happens.
Oh and four double whiskies, now I come to think about it, which is actually 560kcal, oh well.... close enough for government work... CICO is true, always and forever, but it is not useful, partly because it is impossible to measure all the things, and partly because you may be able to starve yourself thin but you can’t starve your lipostat back into working order.
I would expect that you have an easier time getting in and out of ketosis the more you do it. That happens to most ketoers. At this point, I barely notice a difference either way, except hunger (or lack thereof).
Very cool with the weight loss. Interesting that it works in parallel to my own recently, which has been the best in .. 3 years or so? But in my case, I think it's the ACV heh. Almost no appetite at all..
Wonder too if this is just going to work better and better the longer we avoid PUFAs.
