I think that we have lost all perspective on what healthy is, tbh.
Every study shows that if a level of activity and mostly a good diet is followed then being overweight doesn't impact on our overall health and lifespan.
Being overweight and obese are two different things, entirely, it is the difference of liking a social drink and being a raging alcoholic for 10 years.
I have Lupus, i attend my hospital for regular appointments, i took part in a trial which included disease screening and full bloods, my score for all major illnesses/disease was in the very low category, which surprised me as i was bordering on obese, at the time (i had just come off steroids and was recovering from blood clots through Pneumonia).
My consultants explained the effect of diet and lifestyle on the body. Weight only starts to matter when it reaches a certain level, which is more than having a stone to lose, if that person's general lifestyle was good.
I am Vegan at home and Vege when out (for practicality), reading through the cheap/healthy meal thread, i was amazed that pasta and cheap meat was considered healthy and veg was a "bulk-er" and not part of the real food ingredients.
I think we have lost all focus and relay on unsupported claims about health and weight via "Women's/health" articles/magazines.
If we held up Women from some African nations as an example to how we can all look, most of us would have to starve ourselves to death. If we held up other women who have well padded arses and thighs, then many would need fat injections. We come in different shapes and sizes.
