Day 11
Down 2.2lbs overnight - definitely water loss with reduced insulin. Ketones at 1.3 and morning glucose of 80 = 3.4GKI… This is my normal keto state.
Stress is the same. Sleep is the same. Carbs were the same (if not a little higher) last night. The only difference is my protein intake is down from 160g (& much higher) to a strict 100g. I wasn’t hungry - the clotted cream made sure of that!
This reinforces my view that excess protein will not just be lost. It will be de-aminated to remove the nitrogen and the remaining molecules will be converted to glucose. If the insulin spike stays longer, that glucose will be stored as fat. This is not gluconeogenesis (GNG) due to low glucose (which demand driven). This is GNG due to excess supply that must be captured by the body.
So - all else the same - 160g protein spikes my blood glucose and 100g does not… this is on a weekday with weightlifting and sauna.
If I look at this from the glucagon-prime perspective, the energy intake macros served the need without requiring much glucagon to boost glucose. There’s an abundance of dietary fat too and that metabolism should make sufficient glucose. So neither glucagon nor insulin are needed in abundance to manage the energy balance.
