Well, there are so many ways to go depending on what you read and believe. I've recently done the same thing. I have decided to go gluten free and avoid night shades. My goal is to eliminate chronic inflammation and control autoimmune issues (Lupus). Weight loss would be an added benefit.
In all of my research, I have found articles to support avoiding: Gluten, dairy, meat, chicken, carbs, and night shades. That pretty much leaves you with just fruits, vegetables and fish. That might be a bit over board. If your goal is weight loss and lower blood pressure, there are so many diets to follow it makes your head spin. The one that makes the most sense to me is to limit salt, sugar, processed foods, carbs, breads, and desserts. Eat more vegetables and fish. Start juicing. Exercise.
That's my input.
