It does sound a bit on a weird side- 8 blackberries? As a snack or what? Or it just mean that you know exactly (to the last berry) what you're eating?

The 50 lbs weight fluctuation ARE important. They could be caused by eating habits (there goes the ED) and/or health problems, stress, medication...But they are unhealthy for your body and need to be dealt with. As much as I agree that the overweight person could be much more healthier than a thin person (actually some doctors agree that being slightly overweight is better for your body than being slightly underweight), weight fluctuations are causing great stress on your whole body (heart, joints...). So I would look into the reasons behind them. And I repeat ED is only one of many.

However, even if he thinks that you may suffer from some kind of ED it surely doesn't mean that he also thinks that you're huge and disgusting.
