Hi and welcome.
No and no... sorry.
Make your mayo with GOOD olive oil, macadamia oil, or avocado would be good too but I haven't tried it.
Grains are not great, any grains. Forget about toast and cereal breakfasts and treat it the same as lunch or dinner. Have some fat, protein and veg. If you're stuck for time veg rosti or frittata are quick, easy and tasty, leftover dinner is also easy and quick.
