I bought some c8/c10 MCT oil to help a friend with brain issues, but I wanted to verify it did the needful.

According to https://doi.org/10.3390/nu15051148 I should see a effect in 30m, but peak effect in 60m.

I took a 70g dose, 5 hours since I'd eaten anything

measured baseline ketones of 1.1

at 30m, I was only at 1.2

I started to wonder if I had fake mct oil.

at 60m, I had ketones of 1.7

This matches the paper's response curve well enough. A 0.6mmol/l rise in ketones for a 70g dose.

Obviously I would prefer my friend get into a ketogenic metabolism rather then loading up on exogenous ketones, but they are unable to change their eating pattern, so this is a harm reduction strategy

Downsides:

  • Extra fat in the body (not burning stored fat)
  • Oxidative stress from the oil
  • Plant Sterols in the oil (interfering with cholesterol)
  • expense
  • This isn't ketosis, it wont help with blood glucose and insulin

Upsides:

  • Energy for the brain that bypasses high insulin resistance
