I'm the same age and I find her lacking in credibility and rather embarrassing.
She'll sometimes tack on a caveat at the end of one of her preachy rants but is usually very judgemental and prescriptive about her Way of Life, despite being a massive hypocrite.
It comes across as someone desperately looking for a purpose and structure in life. Up early, supplements, powders and potions at set times throughout the day and minimal food that will NOT provide all the essential nutrients (hence the truck load of pills). We're designed to consume actual food and haven't yet evolved to live on a Super Pill.

She loves to promote her very selective research. Arthritis and knee pain doing well, I see.
So easily distracted by the latest fad. Not long ago it was all HRT and everything was related to the menopause. Now that's all gone. Wonder what's coming next?
