I came to this after researching nutritional guidance for a friend with advanced osteoporosis. She won't take my advice. She's a beautiful, bird-like vegan with many food intolerances and food dislikes. She has never eaten a fully-balanced diet.
That led me to become interested in women's (often unconscious) attitudes to food. I found many, many women who automatically give the larger protein portion to the men. I found, of course, thousands of women with long-term eating disorders. I also noticed that, amongst the smaller-portion women, there were many who snack later: this may well be due to protein insufficiency but a yoghurt, crisps or chocolate bar won't compensate nutritionally.
I'm just throwing this out there in case anyone's interested.
