@user_ch53e9c09 I am not a fan of any particular diet, per se. My focus is to eat whole, natural foods as much as possible. In particular I avoid preservatives, artificial sweeteners and most "fads". Based on my various diagnoses I limit: fats, carbs, dairy, oxalates, potassium, phosphates and fiber. What this means in reality is:
Drinks: No soda, rare alcoholic drinks (1/2 glass wine with holiday meals), a great deal of water. I drink a mixture of 18 oz. hot water with 2 oz. coffee. This is my daily indulgence.
Vegetables: All well cooked except cucumbers and some tomatoes. My favorite is roasted (spray pan with cooking oil, place cut vegetables on pan, spray vegetables with cooking oil, sprinkle with salt and bake at 375 degrees for 20 minutes), but I also steam and boil them. Nothing green and leafy. No root vegetables except carrots and an occasional turnip.
Fruits: Fresh fruit as much as possible. Frozen or canned without syrup occasionally. No juices (I find them to add a great deal of sugar without providing fullness). No berries except strawberries. I eat a banana every day, an or apple orange occasionally, peaches (fresh in season, frozen when not), strawberries fresh or frozen.
Meats: Chicken breasts or thighs, fish, and beef roasted, grilled or braised using herbs.
Carbohydrates: Boiled white rice, pasta, rice cakes, and occasionally white bread (as close to natural as possible, read ingredients).
Desserts: These are my indulgences, picked with consideration as "best" choices for me. Angel food cake, ginger cookies (baked as pan bars), spice cake, and vanilla ice cream.
I sometimes use Jiffy peanut butter for a protein boost.
I think of my diet as what I normally eat, not a list of foods that I eat or limit for a certain time and then "go back to normal".
I have heard good things about the Mayo Diet, so you might want to try that. I am not a fan at all of the keto diet I have had too many episodes of ketoacidosis as a diabetic to want anything to do with that "diet". I have heard that it may work if you use it intermittently with a good meal plan.
I hope you find what you need and do well. Blessings.
