No, Medical sites and doctors statements are not enough - I want concrete scientific proof that obesity causes diabetes and low testosterone. This is something I requested and you cannot give me. Because it doesn't exist. People (Doctors included) have been assuming that being overweight causes these things, but the scientific research does not support this. Look into it and get back to me when you find some recent studies.
The only people claiming otherwise are fat people. At the same time they have diabetes, low testosterone, heart problems, etc. Yet they just continue to stuff their fat face, breed more fat children, and speak non-sense.
It's like me saying to provide concrete evidence that being overweight does not cause these things. You can't so technically you cannot disprove our "theory".
Here, right from your sciencedaily site which you admire so greatly.
