What not to eat in rants

I was listening to a health channel last night as I was falling asleep - if I followed all the instructions on what not to eat, I’d lose weight for sure - there’d be NOTHING on my plate.

No wheat - actually no grains at all; no dairy (cheese is no good anyway as it irritates the arthritis); no nightshade veggies - potatoes, tomatoes, peppers, eggplant (they all irritate arthritis); no sugar (limited fruit); no processed foods.

Gee, I guess fresh fish and greens. Over and over again. Yikes.
