My road to health was gradual. I first started using raw goat dairy for the family when my youngest was about 4, as she can’t tolerate cows’ milk. (I can’t tolerate any dairy w-casein). Both she and her brother never needed braces, even though their prenatal nutrition was bad. The older kids did. I started with WAPF diet, but moved to GAPS due to issues with grains. I consider GAPS a subset of WAPF diet.
Between following GAPS, homeopathy, and supplements, I now no longer have constipation, which I was “born with”. My allergies & asthma are almost non-existent, and I used to have to wear a HEPA mask to work in my garden! Migraines stopped as soon as I stopped grains and sugar, as did brain fog. Even though I have MTHFR, I’m able to detox sufficiently now. I know this isn’t strictly a “WAPF” story, but as I said, I believe GAPS “counts”.
Regarding obstacles, I did not have it as hard as many Americans, in that for the first 15 years of married life, I lived in the UK, which at that time, had almost NO convenience foods. You bought meat, vegetables, etc, and you cooked them; no taco kits, open-and-serve, etc. So I was used to cooking. I also had always liked liver, so I was already eating that on a regular basis.
The biggest challenge is realizing that family members (my youngest is now 20) have to find their own ways, which sadly involves their bad choices. When they get sick enough, they may be motivated to change. Until then, I keep cooking good stuff, and keep my mouth shut. Nobody is convinced by being nagged.
