Here you go, this is just the literature I found in 5 minutes on mechanisms for why people tend to return to their original weight after losing weight, but then stop gaining: https://academic.oup.com/edrv/article/38/4/267/3892397?login=false https://academic.oup.com/edrv/article/38/4/267/3892397?login... https://www.nature.com/articles/nature05026 https://www.nature.com/articles/nature05026 https://www.festiwalbiegowy.pl/sites/default/files/upload/regulaminy/otylosc https://www.festiwalbiegowy.pl/sites/default/files/upload/re... - zrodlo.pdf https://www.sciencedirect.com/science/article/pii/S1550413112002926 https://www.sciencedirect.com/science/article/pii/S155041311... Here’s a CDC study showing that there is a long term trend of people getting more exercise even as obesity rates rise: https://www.cdc.gov/nchs/data/nhis/earlyrelease/EarlyRelease201803.pdf https://www.cdc.gov/nchs/data/nhis/earlyrelease/EarlyRelease... My broader point is that, yes, external factors like low activity lifestyles and a diet that contains too much processed food are contributors. But what they are contributing to is an internal mechanism as well. Explain why some rail thin people get no exercise and eat nothing but garbage? Why do some fat people eat whole foods based diets and get daily exercise, but persist in being fat? When people regain weight, why do they tend to regress back to their original weight range, but not continue beyond that? Why has modern medicine been relatively unable to treat obesity until we started injecting GLP-1 hormone analogues? Why has saturated fat consumption been dropping as obesity has been rising? Why has refined sugar consumption been dropping with no effect on obesity? The science on root causes of obesity are evolving quite a bit. I would hope you are more open minded to hearing from your patients and experts in the field. Treat your obese patients with more dignity, and don’t treat their condition like it is a moral failing, or something entirely within their control. Talk to your patients about the level of effort some of them go towards losing weight. You might be shocked to learn the amount of literal blood, sweat and tears expended, and how much their efforts are seemingly in vain. Everyone, not just doctors, know that eat less, eat better, exercise more is the recommended way to lose weight. But it just doesn’t work in the long term.
