People can argue until they're blue in the face but if you eat less calories than you burn you will lose weight. The problem is people with trauma plus a food addiction are not able to do this.
Is there any research around where you live and propensity for morbid obesity - especially living by the sea? I could only find one study which did support this theory but it was in the UK. I live in Bondi Beach where socialising is essentially exercising - surfing, swimming, kayaking etc etc and anecdotally I don't think I've ever seen a morbidly obese person in over 30 years (I know this sounds ridiculous and maybe it's because they never leave the house but it's true).
