calories in/ calories out is the formula for weight loss/ gain. I agree with your assessment, the average person you come across has no rhyme or reason to what they are eating and in what quantities as well as lack of any physical activity/ training and sitting at a desk all day. In addition to all the other factors you listed I would add poor sleep and social media creating depression and unrealistic standards for achievable health goals among many other things. Lack of any of these healthy habits and the understanding of proper nutrition/ training is probably the leading factor for obesity, not that this iron thing couldn't be a contributor as well but probably not as big, I'll admit I haven't looked into it much.
