I was plant based for years but finally switched back to an omni diet for health reasons. Animal protein is more nutrient dense, bioavailable and delivers protein at lower calories and with far less starch than say beans and rice.
I got diagnosed with PCOS (typically driven by insulin resistance or chronically high insulin levels) while plant based and I also started losing hair. It was just too much starch for me, even with distance running. I also was not a big fan of a lot of the protein sources being highly processed and full of seed oils.
My health is a lot better now, joints are even more stable, so no more sprains. Lean mass has increased and no more concerning signs re: bone density. My fasting insulin is back down in single digits, most of my PCOS symptoms have reversed and my hair grew back. Far less brain fog with less starch and choline from eggs and reactive hypos are no longer an issue. They used to feel like panic attacks and I'd get light headed in public, just miserable and upsetting.
If there are medical reasons for the recommendation, I'd consider them. I buy a lot of meat, eggs and dairy at the farmer's market so feel good ethically about that both re: animals and re: supporting local businesses and family farms. They tend to have regenerative practices. YMMV.
