In case you haven't seen it, a new book by a biochemist on managing spikes. She gave her 3 top tips on TV.
1 Have a savoury not a sweet breakfast - otherwise it starts cravings through the day.
2 Move around after meals - eg a walk or other activity after meals to reduce the spike.
3 Have vegetables before a meal - fibre lines the gut (I think) and means less absorbtion.
Her marketing is awful - is money a good enough reason to be known as the 'glucose goddess'? - and she has a 'plan' you can buy - all the usual stuff - but I like the top tips and will investigate further.
My friend who has sadly just gone type 1 diabetes following immunotherapy for cancer, so monitors his levels all day, says that tip 2 works.
