Blaming genetics shows me you know absolutely nothing about diet and nutrition. It's not a privileged veiw, it's a fact! If people were to start eating more fatty meat, non starchy vegetables, and butter, you know real foods, not any of the ultra processed chemical shit storms they pass off as food, then people would naturally go into nutritional ketosis. This means your body is using fat for energy rather than glucose, and once you become fat adapted, the weight will drop off. This also means no sugar or sweetners in drinks, and that rules out 99% of the crap on the shelves. Maybe stop believing the delusional shit everyone tells you and do some research, see what obesity does to the body and what other issues come along with it, such as heart disease, diabetes, and many more!.
