Apparently Jane has had both knees replaced, was never more than 40 lbs overweight, and takes statins and probably drugs for her osteoporosis since she follows conventional "wisdom". I suspect it was all her plant/grain/carb eating and avoidance of animal products that wore out her joints and raised her cholesterol. She has probably never been insulin resistant or had other metabolic problems like the rest of us. I followed her dogma in the 1980s and just got hungrier & fatter. I just looked up the full title of that book: Jane Brody's Good Food Book: Living the High-Carbohydrate Way; I remembered the first half, but the last half explains why it failed me.
