She edited the question since I answered…
So my comment is answering something different
Okay, with the new question, it looks like swapping Huel for ham and eggs and milk:
Protein and fat (ie Ham and egg) actually is digested even slower than Huel.
It’s hard to say for sure - we are all different and our constitutions are better suited to different things.
Personally if I ate meat for breakfast I would feel like a slug for the rest of the day. My digestion can’t seem to cope with anything that isn’t porridge or Huel or cornflakes and plant milk for breakfast. A full English would wipe me out.
But I know plenty people who need protein for breakfast and find carbs in the morning makes them hungry by 10/11am
