I understand importance of viewing our bodies positively. If we replace healthy lifestyles with body positivity thinking, however, we are living hypocritically. It is by doing everything we can to live healthy that body positivity thinking becomes life enhancing as opposed to the brave face people put on for dealing with a hostile society.
I lost at least 30 pounds over two years simply by doing my best to live healthy. I have kept the weight off for at least 18 months because the lifestyle changes are my choices, as such the weight loss is sustained and sustainable.
Living hypocritically with respect to our bodies is worse than having bodies we would like to change in some favorable sense.
