Who here has trouble losing weight? Why I could not lose the weight baffled me. Well, it’s actually more complex than I thought. First, a lack of self-control is usually the knee-jerk assumption as to why you gain weight. This is based on the belief that weight loss is a simple matter of thermodynamics: one takes in more calories than one “burns”. That is true – but only to a point. I take a combination of psychiatric medications; the resulting weight gain is what the scientific literature calls “antipsychotic induced weight gain” (AIWG) (Lett et al., 2012, P. 242). Knowing mine is AIWG is frustrating: It is why my 900 calorie diet and exercise regimen do not work.
