I totally disagree.. even though I wish what you've written could be true! I think that fat and happy are mutually exclusive and can't co-exist. Happiness and well-being are sort of chemical reaction in our bodies, you can't be full of toxins and be happy, toxins are poisoning you. If you are healthy and happy, you just won't be fat.
Not that skinny means happy and healthy - you can be skinny and still be full of toxins and have all sorts of deficiencies..
"Accept your own body completely and give a middle finger to the weight loss brigade. Practice healthy eating and workout routines and maintain a healthy lifestyle." - if you really can do that, you just won't be fat.
