Gary Brecka & Rose Ferguson Live Q&A on Diet, Nutrition and Eating for Longevity | TUH #213

About this video

A live London Q&A with nutritionist Rose Ferguson covering protein supplementation, rosacea drivers, supplements for a teenager at boarding school, hair loss and alopecia, keto and keto flu, and heavy-metal detox testing. Brecka repeats his central claims about folic acid and cyanocobalamin — arguing, in his view, they are synthetic forms the body handles poorly and that folic acid in pregnancy is linked to postpartum depression — while Ferguson stresses finding the driver of a symptom and giving a diet change long enough to judge.

Key takeaways

• Brecka claims methylated B vitamins should be the default choice, in his view
• Ferguson argues skin and hair issues should be traced to a driver such as thyroid, stress or gut health
• Brecka claims keto flu is driven by sharply increased sodium needs in ketosis, as he explains it
• Ferguson advises trialling a diet properly rather than judging it after a few days
