This diet is super healthy and does allow plenty of choices: meat, fish, vegetables (peas & green beans are fine), nuts (not peanuts which are a legume), fruit, «safe starches» (rice pasta,
sweet / white potatoes and white rice),
wine (which I like but don't drink
due to Rx), healthy fat like lard, butter, cream, olive oil and coconut oil, dairy, chocolate, eggs, fermented vegetables and some safe sweeteners such as rice syrup.
