when i first started paleo-eating around a year ago it followed a rather scary blood panel where i learned my fasting blood sugar was over 300 after a 24-hour fast... this was following being a very strict gluten free vegan for a while (peer-pressure driven to thinking this was the way to go!) it also took me around 3 months to see any results after changing to a very strict "whole 30 all the time" style diet. but I did feel better after only a few weeks.
one big change-- the strongest driver of all for me-- was cutting out ALL SWEET TASTES. no sugar or artificial sweeteners or even fruit. I find now that even almonds and carrots are "sweet" to me-- a slice or two of beet is like what a candy was before. but i am shocked at how "tolerant" my system was to the sweetness taste. however, this may not be everyone's experience.
in my opinion everyone has very different blood glucose responses to foods and food combinations. my husband can eat fruit and bread all day and have low blood sugar. i look in the general direction of a packet of splenda and find myself feeling manic. don't even get me near a lara bar-- dates destroy me. however, downing a pound or more of cooked chicken doesn't phase my blood glucose, despite the fact that a large protein bolus is "supposed to" cause a spike (or so I have heard). i don't know why this is this way for me, but i go with it because it's my personal experience. unfortunately reading too much internet often spurs me to try alternate approaches which are never as useful to me as just going with what i've figured out through self-tracking and discovery.
you are doing a good thing by tracking this with your mom-- if you both have the time or energy, i would also track exactly which foods and in what amount were consumed, and how long the break between eating periods. it's annoying and data intensive, but to best understand how to progress you need to first understand what you're working with!
