The shakes in the morning are either as soon as I get out of bed or after I've had my shower (which on week days is immediately after waking). That's why I've been having a few almonds to try and keep me going until I can get breakfast. May be I should try something with a small amount of carbs. I don't seem to spike after Aldi Milk and cereal breakfast biscuits. I might try just one as I wake and see if it helps.
I really need to get a grip of this and make some headway, as its really affecting my day to day life. I take my hat off to you all that have been dealing with it for years, especially without a diagnosis and support from the medical profession.
From what you are saying, your trigger may involve physical activity after being at rest.
(that is just speculation)
If that is the case, you may find full keto adaptation (the kind that happens after 4-6 weeks of seriously consistent keto eating, and no carb/bg swings) as an amazingly liberating experience. It happens when the body properly switches to ketones as fuel, and the ketones become your default setting. It is
not the same as just 'being in ketosis' and 'having ketones'.
Phinney explains it very well in some of his you tube videos - using his experiences of working with keto adapted endurance athletes.
He explains it as running on ketones gives you many thousands of calories of fuel at your disposal - effectively as a bottomless fuel tank. while running on glucose, your readily available fuel reserves are your current blood glucose and glycogen stores - which are tiny in comparison.
Some of his athletes run 100 mile races, never hitting 'the wall' becase they are running on fat, not glucose, so they just have endless ketones, and endless energy. I am, of course, paraphrasing.
